This project in Brixton required waterproofing on shop roofs and residential walkways, so a quick-curing system was a must to keep any disruption to a minimum for the business owners and residents.Specification – Systems UsedThe contractor was looking for a long-lasting and quick-curing system with an aesthetically pleasing and seamless finish – even on the most detailed areas.Therefore, we specified our OptiFlex-Rapid PMMA liquid waterproofing system to meet all of their requirements. OptiFlex-Rapid is our fastest curing liquid system with a typical curing time of just 20 minutes – ideal for projects with limited timescales. This system is cold-applied, reinforced with 150gsm matting and is suitable for year-round application.Build-up & Life ExpectancyThe build-up specified for this project consisted of our:Self-Adhesive PrimerSelf-Adhesive VCL (Vapour Control Layer)OptiFlex-Rapid Liquid Base Layer150gsm MattingOptiFlex-Rapid Liquid Top LayerOverall, the system is estimated to have a life expectancy in excess of 25 years.Challenges PresentedThe only challenge usually presented during an installation such as this would be the amount of roof detailing required. However, using a liquid system such as OptiFlex-Rapid made this process far easier, as it can be applied using a roller or brush for a durable and precise finish, particularly on detailed roofs.ResultsAs with all of our projects, our OptiTec Approved Contractors ensured a professional installation with fantastic results!

One of our latest projects was for a school in Barking, East London. The school required new waterproofing on their roof and chose OptiTec because we have a range of suitable products to choose from, offering excellent durability and longevity at a great price.Specification – Systems UsedFor this project, a long-lasting system was required with a Broof T4 fire classification for safety. Our technical team advised the OptiPlan-FB (PVC Single Ply) system for this project as it met the brief safety-wise, but it’s also excellent value for money over a large area.The OptiPlan-FB system is a fibreglass reinforced, fleece-backed synthetic waterproofing membrane made from premium quality PVC-P, offering exceptional resistance to weather and UV rays. A great benefit of this system is that it can be installed year-round due to having excellent flexibility in cold temperatures.This system was installed by an OptiTec Approved Contractor to ensure the highest quality of fitting with the option for a labour and materials guarantee if required.Challenges PresentedThere were no real challenges presented during installation and everything ran smoothly. We have a technical team on hand at all times to provide support and advice where required so we can always overcome any challenges presented in the best way possible.ResultsThe results of this project are fantastic and the client has expressed their satisfaction with the professional installation of the system and the overall finish.

We have recently completed a 600m2 project in Westminster with installation by one of our main Approved Contractors, Ridgewell Flat Roofing.Specification – System UsedThis project called for extremely durable yet cost-effective waterproofing to be installed, which made the OptiTorch-Premium Bituminous Felt System the ideal choice. Having been used in the roofing industry for over 50 years, felt has been consistently developed and improved, and still remains one of the most popular systems available.OptiTorch-Premium bituminous felt is a high-performance waterproofing system that can be installed year-round, with excellent flexibility at temperatures as low as -25oC. This system provides long lasting resistance against UV rays and even contains special additives to protect against root growth.There was also a lot of detailing work and some gutter repairs required, so OptiFlex-Rapid PMMA Liquid was used for these parts of the project to ensure a completely watertight and visually appealing result.OptiFlex-Rapid is a quick-curing PMMA liquid waterproofing system with a typical curing time of just 20 minutes! It is cold-applied and is reinforced with 150gsm matting for extra resilience. OptiFlex-Rapid can be applied year-round and is a great choice for detailing and repair work as it can be applied directly onto most surfaces without the need for primer, which can often save time and money!The ProjectThis project was a 600m2 warm roof design with a standard build-up including 120mm tissue-faced PIR insulation, and also consisting of: OSA5 Primer, Vapour Control Layer, Insulation Adhesive, Insulation, Premium Self-Adhesive Underlay and Techno58 SBS Capsheet.Ben Ridgewell, owner of Ridgewell Flat Roofing, took on the project with Grant Jones (Co-Director) and his team, and completed the installation to their consistently high standards with an impeccable finish.The ResultsThe overall completed look of this project is very tidy and aesthetically pleasing – thanks to Ben and his team for a great installation, including an OptiTec warranty of 20 years to ensure peace of mind for the building owner for years to come.
