Newton Waterproofing Systems

As part of the Wandsworth regeneration programme to increase the number of affordable homes, Wates Residential were awarded the contract to build a new, six-storey block of apartments on the Shuttleworth Road.The structure included 59 concrete balconies, all requiring waterproofing with a product with a minimum fire rating of A2-s1-d0, tested to BS EN 13501-1.Not only were Newton able to recommend a product that had already been used on a similar project this year, they were also able to recommend the expert services of Newton Specialist Contractor Arti Structural Waterproofing.The minimum fire rating of A2-s1-d0 now precludes the polyurethane and polyurea products that were commonly used on balconies, so Newton recommended the cementitious and modified-polymer Newton 103-S membrane. As well as carrying the required fire rating, 103-S can resist extremely high positive and negative water pressure, forming a hard, durable coating with a degree of elasticity that makes it ideal for protecting concrete.Arti also used Newton 203-RM to create smoothing fillets, and Newton 912-RT to reinforce the 103-S over the joints, details and changes in direction.On site, Arti also needed to work flexibly, as the programme could not proceed without the waterproofing and fireproofing of the balcony upstands. However, due to the propping of the concrete formwork to the floors above, Arti had to execute their installation in two phases of efficient and detailed waterproofing.Thanks to a meticulous eye for detail, as well as careful planning and thorough preparation of the concrete balconies, Arti were able to complete the waterproofing of all 59 balconies in two stages. This was managed as well as delivering the required A2-s1-d0 fire rating, and the installation was completed quickly without compromising the programme of the build.

Built in 1855 as an Elizabethan School for local children, the historic and landmark Castle Club has also been a children’s hospital, youth club and private residence in its long history.Since being acquired by property developers Thackeray Group however, the Grade II Listed building is now to be converted and extended as a specialist care home.The work includes not only the restoration of the historic gothic structure, but also the building of a modern four-storey extension to the rear, including a 5,000-square-foot basement extension.

Newton System 500 fulfils all Listed Building requirements in this Georgian Manor House. Newton Pumping Systems installed to manage waste water, including two Newton Titan pumps and battery backup systems.

Leafy Windlesham in Surrey was the location for this 5-bedroom, £15,000,000 mansion by Searchfield Homes, complete with a 4-metre deep basement containing a swimming pool and spa pool, all of which needed to be protected from water ingress and ground gases.

To facilitiate their exciting BSc Paramedic Science course, the University of Surrey identified that they needed more practical training space for their students. By working alongside Scott Brownrigg Architects, Newton Specialist Contractor Advanced Basements, and the Newton Technical Team, an extensive existing undercroft was converted into three large, dry rooms that are ideal for the purpose.With an emphasis on practical elements, the exciting BSc Paramedic Science course at the University of Surrey needed a new, well-equipped training facility for its students at the Surrey Research Park, Guildford.Having identified a large existing undercroft for the purpose, the University consulted with Scott Brownrigg Architects, as well as the Newton Technical team and Advanced Basements in order to create a new, dry space.The extensive undercroft area was first separated into three large rooms, based on what each room was going to be used for. These were defined as:A live environment Paramedic Training room, with an existing concrete floor, concrete retaining walls, and blockwork internal wallsA storage area, requiring a new insulated floor, and with concrete retainng walls and blockwork internal wallsA plant room, requiring full internal waterproofing to the walls and floorConsidering that the existing structure was already quite robust, Newton and Advanced recommended an internal Type C Newton CDM System. This method of waterproofing is the most failsafe method, using membranes to capture the water, and sump chambers and pumps to collect and remove it. The pumps are also supported by a battery backup system for total security.Advanced Basements acted as the specialist waterproofing contractor and the waterproofing design specialist on this project, working alongside the architect and client to design the system, before providing a high quality installation.Furthermore, thanks to their early involvement, Advanced also took design liability for the project and guaranteed the installation for the client.

When HSP Architects and Price & Myers wanted to transform a listed commercial basement in Temple Fortune to create a new community centre, they needed to look no further than Newton Specialist Contractor Arti Construction to perform the waterproofing.ning three of the walls were either fully or partially below-ground and suffering from water penetration. Arti recommended the Newton CDM System, as it is the most safe and reliable form of waterproofing that would deliver a completely dry internal space and cause the minimal amount of disruption to the Listed structure.The basement, part of a four-storey Listed building, was built into a hillside, meaning that three of the walls were either fully or partially below-ground and suffering from water penetration. Arti Construction worked with the design team at an early stage to design a waterproofing solution.With existing Listed basements such as this one, Arti Construction were quick to recommend a Type C cavity drain waterproofing solution in the form of the Newton CDM System. Type C waterproofing is the safest and most reliable form of waterproofing that will deliver a completely dry internal space, whilst also causing the minimum amount of disruption to the Listed structure.Before Arti could proceed with the installation, they first had to re-level the existing concrete slab in order to provide a flat and stable floor.With the structure fully prepared, Arti could then proceed with installing a full cavity drain waterproofing system. This consisted of installing Newton 508 with minimal MultiPlug fixings to the walls and floors to capture the ingressing water. The water is then directed via Newton Basedrain channels to a Titan-Pro sump chamber, for removal by dual NP400 clean water pumps.The complex basement space included existing columns, windows and an internal staircase which all had to be factored into the waterproofing design.Regardless of this, Arti Construction completed the 280m2 installation within budget in just one week, delivering a reliable Type C structural waterproofing system that is also compliant with British Standard 8102:2009.

Newton Specialist Contractors ASF Waterproofing were called in to investigate why the Bridge Master’s Quarters at No.1 Tower Bridge was suffering from damp and proceeded to install multiple Newton products to resolve the issue.At the world-famous Tower Bridge, landscaping contractor Maylim was commissioned by the City of London Corporation to investigate why the Bridge Master's Quarters at No.1 Tower Bridge was suffering from damp.After excavating, they discovered that the structure had no effective damp proofing protection. Newton Specialist Contractor ASF Waterproofing were commissioned to install new damp proofing measures to solve the issue.ASF Waterproofing approached the project in two phases, using multiple products to effectively damp proof both inside and outside the building. At the start of phase one, ASF correctly prepared and cleaned the internal wall surfaces before installing a new damp-proof course by injecting Newton 804-DPC into the walls at regular intervals, then sealing the holes with Newton 313-WP. The walls were then smoothed with a new internal render, ready for Newton 103-S to be quickly and easily sprayed to provide a final barrier to water.For phase two, the ASF team turned to the external walls of the structure, preparing and cleaning the surface before applying a new external render coat. The wall was then thoroughly waterproofed with four coats of the flexible, resilient Newton 109-LM. To ensure that the building was completely protected externally, the waterproofing began at 1 metre below ground level and extended all the way up to the existing windowsills.Thanks to their meticulous attention to detail and high standard of installation, ASF Waterproofing were able to provide both the contractor and the client with a high-quality and comprehensive damp proofing solution. As a result, the City of London Corporation can now hand over the building to the new lease holder, safe in the knowledge that it is well protected from damp.

Newtons help defeat damp in this remarkable building using Newton System 800. Due to the age of the castle, there were significant rising and penetrating damp problems, for which Newton damp proof membranes were the ideal solution.

Newton System 800 used to damp proof a school in Brighton which required multiple damp proofing treatments as part of its refurbishment. Installed by Newton Specialist Basement Contractor CavityTech.

The King Edward VII Galleries is a Grade 1 listed structure and part of the iconic British Museum complex in London.Constructed between 1907 and 1914, the building sits above a series of tunnels and ventilation shafts, which serve to supply air to the gallery via an external ventilation unit.Due to water ingress in the tunnels, there was serious concern as to the quality of air supplied to the gallery, and the impact that this might have on the artefacts kept there.

Newton Specialist Contractor Garratt’s Damp and Timber provided their waterproofing expertise as part of the refurbishment of this high-end commercial property in the prestigious London Borough of Chelsea, as the basement area was experiencing high volumes of water ingress.

An impressive basement extension, housing a swimming pool and sauna, required a robust waterproofing solution at this large country home.Newton Specialist Contractor Stonehouse were brought onto this large residential project to waterproof an underground extension including a swimming pool and sauna. Set in a small village in Berkshire, the impressive countryside home was designed by architects Spratley and Partners.For the new below-ground structure, Stonehouse were required to install a failsafe and maintainable waterproofing system that would completely protect the luxurious basement from unwanted water ingress.Ensuring that the project was fully compliant with BS 8102:2009, Stonehouse recommended a combined waterproofing solution using a Type B reinforced and water-resistant concrete structure designed to BS EN 1992, combined with a full Type C internal cavity drain membrane system.As the most reliable and completely maintainable Type C waterproofing solution, the Newton CDM System was the ideal choice for this structure. Firstly, Newton 508 membrane was securely fixed to the internal walls of the basement using Newton's specialist MultiPlug fixings.Any water that is captured by the membrane is then drained away with Newton Basedrain channels, and pumped out of the property using a Titan-Pro sump chamber fitted with two NP400 pumps and supported by a failsafe battery back-up system.As an extremely experienced waterproofing contractor, Stonehouse were able to confidently recommend, design and install a comprehensive and truly failsafe waterproofing system that will protect the property from unwanted water ingress for many years to come. Stonehouse also provided complete peace of mind by offering a 10-year guarantee on the installation.

For this residential project on the Island of Jersey, a homeowner was building a private underground car garage with their own tennis court on top. To help ensure a completely dry basement, Rateavon Jersey installed Newton’s injection hose waterbars in the construction joints.

Newton Specialist Contractor Arti Structural Waterproofing are a leading expert in all forms of residential and commercial waterproofing, with a reputation for delivering high-quality waterproofing installations. For this project, Arti had to provide a reliable and watertight solution to a Listed basement with strict conservation guidelines.

Beneath the streets of Central London lies a network of Grade 2 Listed underground vaults. As Newton Specialist Contractors, Stonehouse were called in to waterproof four of these impressive structures and turn them into a completely dry commercial space. The four vaults were situated just North of the River Thames in Central London, a short walk from such famous landmarks as Smithfield Market and St Paul's Cathedral.The Grade II Listed structures are each over 4 metres in height, and form part of an impressive below-ground infrastructure network. Newton Specialist Contractor Stonehouse were asked to waterproof four of these impressive vaults for the multinational service provider KPMG, in order to turn them into useful commercial spaces.When waterproofing historic vaults such as these, the Newton CDM System provides the ideal solution as it is maintainable, requires minimal fixings and therefore avoids damaging the structure, and crucially is deemed as reversible should the structure need to be returned to its original condition in future.As an experienced contractor, Stonehouse proceeded with an expert installation of a full CDM System to the tricky vaults, including:508 Mesh membrane to the walls, for a direct plaster finish508 membrane and Fibran XPS 500-C insulation boards to the floor.Basedrain channels to direct any captured water towards two Titan-Pro sump chambers, each containing two NP400 pumps.Victron Inverter and a NorthStar battery for reliable backup power.Stonehouse completed an extremely complex and detailed cavity drain installation with precision, resulting in an exceptionally neat waterproofing system, and proving the benefits of using a specialist waterproofing contractor.

Considering the large size of the basement area and its proximity to the River Thames, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the structure.At this private property in South London, the plan was to build a new basement extending below the entire footprint of the house and into the rear garden, incorporating a swimming pool, recreational spaces and wine cellar.However, considering the close proximity to the River Thames and the high water table, Newton Specialist Contractor Stonehouse were called in to provide a complete waterproofing system for the entire structure.Considering the size of the basement area, the high water table, the geographical location close to the River Thames, and the fact that the structure was created using underpinning, the risk of water penetration in this basement was extremely high. Stonehouse recommended the most failsafe solution, the Newton CDM System.Firstly, they installed Newton 508 membrane to all internal walls and the floor, using Newton's ancillary products to fix the membrane securely and seal the system. Drainage channels were also created using Newton Basedrain, feeding into a sump chamber containing two NP750 pumps, a higher capacity model capable of dealing with large volumes of water.Finally, where the basement extended beyond the house's footprint, a liquid waterproofing membrane was used on the new external roof.Stonehouse is one of Newton's oldest and most experienced specialist contractors, and they showed their expertise here by delivering a dry, safe basement for the client that could then be transformed into a beautiful new part of their home. Furthermore, the installation was backed by Stonehouse's 10-year guarantee, for complete peace of mind.

This stunning new-build with floor-to-ceiling glass panels is built into the hillside and thus required a robust waterproofing solution for failsafe protection. After the original property on this site in Barnet was demolished, construction began for a new building that could take full advantage of the stunning location. With floor-to-ceiling glass panels on one side of the property , this new-build is the best place to admire the views over London.Built into the hillside, the property was therefore partially-retaining and required a full waterproofing system throughout to protect from unwanted water ingress. As such, Newton Specialist Contractor Stonehouse were called in to expertly install a robust waterproofing system to the entire structure.The client appointed Stonehouse's Richard Allen as the waterproofing design specialist on this project, to ensure a fully BS 8102:2009 compliant build.Due to the partially-retaining nature of the structure, Richard recommended a combination of Type A, B and C waterproofing systems to ensure a Grade 3 habitable environment. Relying on an effective Type B structure, Stonehouse then applied a cementitious coating of Type A Newton 107F to the external surface of the flat roof decks and to the internal area of the lower lift pit.Given the high risk from water, the failsafe Newton CDM System was also installed on both levels of the structure. Newton 508 membrane was securely fixed to the internal walls using Newton's ancillary products, with water from the upper level being bunded and piped down to the lower level, then drained via gravity fall using Newton Basedrain.As one of our most experienced specialist contractors, Stonehouse expertly recommended, designed and installed a truly failsafe waterproofing system that will continue to protect this contemporary home for many years to come. Furthermore, Stonehouse were able to provide a 10-year guarantee for the installation, for complete peace of mind.

At this new-build shopping centre in Shepherd's Bush, West London, the new underground car park was experiencing high levels of water ingress through two movement joints that had failed. Newton Specialist Contractor ASF Waterproofing, who are specialists in injection resins and structural repair work, was therefore called in order to provide a quick solution and fix the leaking joints.Following an initial investigation, the technical team from ASF decided to use the 5-part acrylic rubber sealing resin Newton 324-SR to seal the joint, as it reacts to form a very durable and flexible seal that exhibits exceptional adhesion, making it ideal for movement joints.ASF began by drilling holes at angle into the concrete, and at regular intervals for the 10mm injection packers above the joints. The injection packers were then fitted to each hole, and foam backing rod was used to temporarily block the joint and prevent uncured resin from escaping as it is injected.The five components of the PC 509 Rubber Acryl are mixed to make two solutions, whilst the curing time of the resin can also be adjusted by changing the quantity of initiator used. The resin was then injected through the packers and into the joint using a three-component stainless steel pump.Finally, once the resin was cured and the joints were effectively sealed, ASF ground back the surface of the concrete to either side of the joints and applied Newton 106 FlexProof, a flexible liquid waterproofing material, to provide a final protective seal and finish the job.With two leaking movement joints in a finished structure, the client required a swift resolution to get the area back into use quickly. With the benefit of Newton’s advanced resin and waterproofing products, ASF got to site and delivered the sealed joints within the client’s tight timeframe.

Installing a comprehensive internal and external structural waterproofing solution to prevent the ingress of ground water.

Fed up of renting in London, Joe and Lina decided to build their own on a tiny 38m² plot of land in East London. With a budget of just under £200k they set about delivering Joe’s innovative concept for a six half-floor house with floating concrete slab, designed to maximise the space into a 83m² home, all whilst being filmed by Channel 4’s Grand Designs. However, things soon went south…Within weeks of the project beginning in October 2015, rogue contractors had performed a disastrous basement excavation attempt contrary to the Structural Engineer’s instructions, leaving unsupported banks of earth falling in beneath the street and shutters bursting inwards under the weight of the concrete.This first attempt, described as “spectacularly shambolic” by Kevin McCloud, more than doubled Joe and Lina’s budget for the excavation from £48k to £100k, and caused months of delays in order to get the project back on track.Having already contacted Newton Waterproofing Systems to consult on the poor workmanship, Joe and Newton soon determined that if he were to save his home and get it out of the ground, he would need a specialist contractor to actively communicate, collaborate and listen to him as both the engineer and client.MJ Rooney Construction came on board as contractors in November 2015, and following discussions to determine exactly what was required, modelled the entire project in 4D to ensure that all potential difficulties were solved before work began.With the right lines of communication in place, work recommenced in late January 2016, with the first challenge being to make safe a 3.5 metre high bank of unsupported earth with sheet piles, before creating a new and waterproof structural shell of reinforced concrete.With the shell of the structure in place, Newton and MJ Rooney’s next challenge was a much more welcome one, as they created a bespoke waterproofing solution to accommodate Joe’s ingenious design for a suspended reinforced slab that acted as both a floor and a prop force against the lateral pressure from the basement walls.This entire slab rested on brackets designed by Joe and his structural engineer, insulating it from the external walls by ensuring minimal contact, and only making contact through insulated blocks with enough compressive strength to take the vertical loading. The design also created a cavity around the slab that can be fully insulated, allowing the slab to be used as a thermal mass inside the building without having to insulate the entire external envelope.Working closely with Joe, a solution was devised that enabled the continuity of the waterproofing behind the brackets without compromising the structural design.

Newton System 500 provides a complete waterproofing solution for a boathouse situated on the River Thames, installed by Newton Specialist Basement Contractor Stonehouse. Newton Waterproofing Systems were contacted to provide a solution for a delightful boat house on the River Thames.The property originally had a wet dock but this had been back filled and capped with a concrete floor. The client wished to use the ground floor as a bedroom, but during a recent flood the water level had reached 500mm internally.Newton System 500 provided the ideal solution, as it works by redirecting the water, rather than trying to hold water back – which would be impossible under such pressurised conditions. Newton 508 Mesh was chosen for the walls, Newton 520 to the floor with a Newton Basedrain ring around the perimeter. Two Newton Titan Pro pump systems were used, which included a battery back up system.Newton System 500 was installed to this property by Newton Specialist Basement Contractor Stonehouse BasementsRather than holding water pressure back, therefore, it was accepted that the river would penetrate the structure and would be pumped out. The system is designed so that ingressing water is depressurised by the Basedrain and then moved around the Basedrain ring to the two Titan sump chambers. The chambers each had 40mm discharge lines exiting the structure. Both pump systems had non-return valves so if the river rose over the level of the pipe the pumps would still be effective.The full waterproofing system was installed in a little over a week. The major test came when the River Thames rose against the property to a depth of over one metre! The Newton System 500 waterproofing system coped with the water ingress as designed. At the height of the flooding, all three pumps in each sump chamber were operational. The system proved to be fully successful.

Internally and externally waterproofing the below-ground developments of the extended Christian Dior store on New Bond Street, with Newton 403 HydroBond, Newton 107F and Newton System 500.New Bond Street has been one of the most prestigious retail streets in London since it’s 18th Century beginnings, and in 2011 was named as the second most expensive retail street in Europe after the Champs-Élysées in Paris. The Christian Dior name has also been synonymous with haute couture and luxury retail since its own inception in 1947.This project required both the internal and external waterproofing of the extended basement area of Christian Dior’s flagship London store. A significant extension of the existing floor space on this stretch of famous London road, the extensive basement area will be used as stock rooms, changing rooms, and staff and shop floor areas. It was therefore a crucial requirement to achieve a completely dry internal space.The property line construction between two existing buildings meant that there was a requirement for waterproofing both new and existing structural elements, including pile caps, underpinning, a new reinforced concrete slab, existing foundations, and also existing vaulted areas at the front of the building which extend below New Bond Street.Because a completely dry internal environment was required, (defined as Grade 3 by the BS 8102:2009 Code of Practice for The Protection of Below Ground Structures From Water From The Ground) the proposal put forward by design specialists G05, in consultation with Newton, was a combination of Type A and Type C waterproofing systems. Due to the fact that the build was between the flank walls of two existing structures, the Type A system comprised of a combination of the hydrophilic, fully-bonded Newton 403 Hydrobond membrane pre-applied below the new concrete slab, and was linked to the cementitious, flexible Newton 107F membrane, which was applied to the internal faces of the walls and the prepared internal areas of the vaults.Following the application of the Type A system, a Newton System 500 Cavity Drain membrane system (Type C) was applied to the internal wall and floor areas by Newton Specialist Basement Contractor Advanced Preservations Ltd, who also guaranteed the work. The system included perimeter drainage using Newton Basedrain, and two Newton Titan-Pro pumping systems. The under-pavement vaults were lined internally with the Newton 500 system.Not only was continuity achieved with the waterproofing systems across numerous below-ground building mediums and scenarios, but the waterproofing system also conformed to the recommendations of BS 8102:2009 for combined waterproofing protection, where even the slightest form of water ingress is unacceptable.The internal areas were also successful in achieving an environmental Grade 3 with regard to their degree of water tightness, meaning that they will be suitably fit for purpose and use by both Christian Dior’s staff and customers.

Newton was approached by the desperate client at this large terraced property in Notting Hill, having had a second basement level excavated beneath the existing basement and the front and rear gardens.Unfortunately, bad waterproofing design and workmanship meant the basement had flooded immediately upon completion – the builder ceased trading and, following a legal case, the architect and structural engineer were found culpable.We recommended our experienced specialist contractor Stonehouse in order to assess the failure and propose a comprehensive solution.The experts at Stonehouse identified a litany of issues, from the weak, permeable structure to the lack of continuous waterproofing between levels, the inadequate pumping system, the blocked cavity drain system, and the non-existent external deck waterproofing and drainage, amongst others.

This old Mill House in Cornwall has undergone a huge conversion and extension to become a luxurious five-bedroom home, protected by the failsafe Newton CDM System. Simon Williams purchased the 18th Century Water Mill in 2015 with a view to renovating, developing and extending the beautiful property, located in Blowinghouse just South of Perranporth, into his private residence.Once planning permission was gained for the required conversion and extension to transform the mill into a luxurious 5-bedroom family home, Simon liaised with CAD Architects on the design, which incorporated a waterproofing design specified by Newton.An additional large garage with charming two-bedroom ancillary accommodation was also added to the grounds of the property, which required specialist steel and concrete foundations, given the close proximity of the water.In order to restore the old mill and achieve a Grade 3 habitable environment, BS 8102:2009 recommends that a Type C internal cavity drain membrane system is one of the primary forms of waterproofing, as it is the most failsafe system that is least prone to defects and issues.The Newton CDM System is also completely maintainable, and was therefore ideal for the 18th Century structure, considering that Williams Creative Homes did not want to compromise the external appearance of the thick stone walls.The proximity of the river also meant that there was a high risk of water ingress, however, Newton's robust cavity drain waterproofing is designed to capture water using Newton 508 membrane on the walls, then drain it away via gravity using Newton Basedrain.Finished to an incredibly high standard by Williams Creative Homes, Simon has been living in the property ever since, whilst the Newton waterproofing system successfully ensures that his home is completely dry and protected.

Newton CWC (Cold Wall Coating) Eliminates Condensation on the Internal Walls. It was installed on the internal walls in this pantry and eliminated condensation completely. Contains unique mineral powders which raise the temperature of the wall.

Warwick Court, the former Goldman Sach's headquarters on Paternoster Square in London, is being redeveloped by Mace Group after they won the £60m project in 2020. Newton Specialist Contractor ASF Waterproofing specified a waterproof and hard-wearing coating system for the floor of the plant rooms. As a result, ASF Waterproofing designed and installed a watertight system utilising Newton 110 WATstop and Newton 701-HB. ASF Waterproofing provided a completely watertight solution following the guidelines set out in BS 9102:2009. The works were carried out to a high standard and delivered on time, despite the tight schedule.

Hammerson House will be a world-class, 116-bed residential centre for the elderly Jewish Community in Hampstead. Newton Specialist Contractor Cast Contracting Ltd (CCL) were approached during the planning stages to develop a comprehensive waterproofing solution for the extensive basement.CCL recommended the installation of a Newton CDM water management system to comprehensively waterproof the extensive basement. First, they employed the 8mm Newton 508 membrane to the concrete retaining walls of the basement. The 50mm thick Fibran XPS 500-C insulation was then installed beneath more 508 membrane across the entire concrete slab. Additionally, Basedrain drainage channel was installed around the perimeter, including inspection ports to provide a fully maintainable system.This entire system is served by a series of complete sump and pump systems, each consisting of primary and backup NP400 pumps, high water level alarms, and battery backup systems. These are all controlled by Newton’s advanced Control Panel-Pro to ensure a failsafe system, even during a power outage.Finally, Newton’s 107F cementitious waterproof membrane was spray applied to the concrete upstands of the lightwells and lift pits in order to complete the continuous watertight solution.

Newton Specialist Contractor Arti Construction got involved at an early stage in this new-build project in Golders Green, North West London, to construct an office basement and 4-storey dwelling containing 7 new flats.

Newton is proud to contribute to the transformation of the unique, Grade 1 listed Cambridge House in Piccadilly as it undergoes conversion into one of London's grandest hotels. The 18,000m2 scheme includes six adjacent Grade 2 listed residences, whilst a four-level basement will accommodate a spa as well as the back-of-house and servicing areas. In order to deliver a reliable, watertight solution for this £165m project, Newton worked closely with architects PDP London and leading enabling works contractor Deconstruct UK throughout the design and installation.

Newton and our Specialist Contractor Premier Contractors were called in to provide a complete waterproofing solution for this new Doctor’s surgery in Tavistock, Devon, after the main contractor found themselves struggling with the waterproofing design and installation on this unusual new building.

The EdCity development is a not-for-profit partnership between national education charity Ark and Hammersmith & Fulham Council. With £150m of investment, EdCity aims to build a place that will make a difference to local people in White City, including:Education and youth facilities: A state-of-the-art new primary school, as well as a nursery, adult community education centre, and a youth zone for young peopleAffordable housing and new community space: Providing 132 affordable homes for local people and key workersOffice space: 10-storey, 95,000 sq/ft net office buildingPublic realm: Public spaces and pedestrian and cycle routes, improving community transport and accessibilityPhase One of EdCity began in July 2021, starting with the primary school, residential, youth zone and office building.The primary school opened in Autumn 2023 and Phase Two also began on the nursery, adult education centre and affordable homes. The project is due to be completed in 2025.The project required a large service tunnel linking the energy centre to the other buildings within the EdCity development.The project engineers Mason Navarro Pledge and main contractor Bowmer & Kirkland developed a construction strategy that utilised precast tunnel sections. In-situ concrete elements were also cast into place where the tunnel adjoined the other buildings and at changes in direction.Finally, the boulevard above the tunnel is also used for pedestrian and emergency vehicle access. The design therefore had to allow for movement in the joints from settlement and future loading.Newton and our specialist contractor ASF Waterproofing Specialists worked together to develop a two-stage solution. The first created an integral seal in the joints using PC 509 Rubber Acryl, a highly elastic acrylic rubber injection resin that was contained within the joints using HydroCoat 203-RM repair mortar and backing rods. As with all bonded systems, substrate preparation was a key element of the installation.The second stage created an internal seal using HydroCoat Monoflex, a flexible waterproof bandage combined with a solvent-free epoxy adhesive. The result is a waterproof seal that is easy to install and has excellent adhesion over construction joints that are subject even to extreme movement.The technique and sequencing for the base, sides and roof of the tunnel were all different, but still needed to provide a continuous seal along, around and through the whole joint.Despite this, ASF were able to deliver an installation of Type A and Type B waterproofing to British Standard 8102:2022

Newton contractor Rymill Property Developments were approached by the owner of an old vineyard in Hampshire, in order to redevelop the site. As well as building an immaculate four-bedroom, four-bathroom Georgianhouse for the client, Rymill also took on the task of creating 3 brand new, modern properties, all with basements built into the existing sloping site. The large, partially retained basement areas would all house a stairwell, plantroom, storage room, cinema room, zen room, two ensuite double bedrooms and a garden room, and so required a completely dry internal environment.

Heavy rainfall on the Orkney Islands meant that the basement room of Kirkwall Air Traffic Control Tower suffered from frequent flooding, with water levels reaching 1.2m at their highest point. Newton Waterproofing and Specialist Contractor Wise Basement Systems were called in to remove the existing water and then waterproof the structure to protect it from future flooding, all in just one week.Kirkwall airport is located on the main island of the Orkneys, 10-miles off the North coast of Scotland. Presented with a logistically challenging location and a tight project timescale of just 1 week, Newton had no hesitation in recommending the expertise of Wise Basement Systems as the specialist contractor to Building Surveyor Pick Everard.Getting involved at the very start of the project, Wise were immediately able to design, advise on and install a system to remedy the 2 inches of water in the existing basement of the Air Traffic Control tower.Cavity Drain Waterproofing, or ‘Type C’ waterproofing as it is defined by BS 8102:2009 is often the most effective means of achieving a completely dry ‘Grade 3’ environment in an existing structure below ground. It was therefore no surprise that Wise Basement Systems designed a Newton CDM System for this existing basement area.To begin, Wise installed 120m2 of Newton 508 on the walls and 80m2 of the recycled Newton 520 eco to the floor, above the closed-cell Fibran XPS 500-C insulation. The drainage membranes were supplemented with a perimeter channel of Newton Basedrain, directed to a Titan-Pro sump chamber containing two NP400 Pumps to remove the water.Finally, to ensure that the system will continue to work in all eventualities, even in a complete power outage, Wise installed a backup system with dual Northstar batteries and a Victron Power Inverter.Even with a project located 10 miles from the mainland, and 1 week to waterproof a basement with only a 600mm wide access hatch, Wise Basement Systems delivered a completely dry space for the client that was also compliant with BS 8102:2009 and backed by their guarantee.

Located in Earls Court, London, the Lillie Square development will eventually stretch from Chelsea football ground to Kensington Olympia, and comprises of over 800 multi-million pound luxury dwellings. The development will also contain London’s largest private residents’ club, which boasts a lounge, library, private dining room, cinema, gym, spa facilities and 20 metre swimming pool with jacuzzi.Lillie Square Phase 1 required the formation of a watertight basement to house the luxury private residents club serving the entire property development. A large portion of this luxury clubhouse, including a swimming pool, spa, sauna, steam room, gym and function room, is below ground. The project therefore required robust waterproofing to protect the internal environment.Newton Specialist Contractor Stonehosue were consulted at an early stage to be part of the design team and provide a guaranteed waterproofing solution that would comply with the requirements of both BS 8102:2009 and any third-party warranty providers.The long-term partnership between Newton Waterproofing Systems and experienced Specialist Contractor Stonehouse has seen both companies partner on a vast portfolio of properties across the UK, and Stonehouse brought this experience to the table at Lillie Square.In order to provide the maximum level of protection, Stonehouse combined two Types of waterproofing in order to achieve a completely dry ‘Grade 3’ internal environment as per the recommendations of BS 8102:2009.The first of these products was the Type A, cementitious, liquid-applied waterproofing membrane Newton 107F, which was particularly suitable to this large-scale project due to the fact that it could be quickly spray-applied over large areas.The 107F was supported by the Type C Newton CDM System cavity drain waterproofing, installed throughout the basement area of the clubhouse, with four Titan-Pro sump chambers containing dual NP400 pumps, as well as Newton High Water Alarms, Inverters and Battery Back-Up protection creating a truly failsafe system.By working with Sir Robert McAlpine at the design stage it was possible to consider the lifetime performance of the structure as well as the cost in order to design and install thorough waterproofing protection.

Newton-trained contractor Structural Repairs are leading national specialists in renovating, strengthening and repairing commercial and domestic buildings. However, in 2020 it was their own requirements that were the focus of their efforts, as they sought to renovate a historic railway arch in Windsor in order to create a new head office for the business.

As part of their ongoing relationship with Imperial College London, Newton Specialist Contractor A.P. Gooch assessed and waterproofed 11 Victorian brick vaults beneath the streets of Kensington, London, after the existing competitor ‘waterproof render’ failed.Imperial College London is a world top ten university, and it's top-class educational facilities in Central London are constantly used by multidisciplinary students, including doctors, and nurses, for their studies. It was therefore crucial for AP. Gooch to perform the work whilst also creating minimum disruption to the college students.Following a full assessment of the vaults, A.P. Gooch decided that the best option was to install the tried and tested ‘failsafe’ Newton System 500 cavity drainage membrane solution in order to depressurise, capture and safely manage ingressing water away from the building. A.P. Gooch also committed to carrying out the entire installation at night in order to cause as little disruption as possible to the College’s students.By installing Newton 508 membrane with strategically placed Newton MultiPlug fixings, the system remained sympathetic to the historic structure beneath. Newton Basedrain was also installed in order to channel captured water to one of four Newton Titan-2 sump chambers, the compact size of which made them ideal for use in a structure with such tight size restrictions. Each chamber also contained primary and backup Newton CP400 pumps to ensure that there will always be a safe means of removing captured water from the building.Now fully protected by a maintainable system, compliant with waterproofing code of practice BS 8102:2009, all 11 vaults are now completely dry, providing safe and healthy individual study rooms for the medical students at Imperial College.
