Hot melt rubberized bitumen cold roof coating system.
Suitable for a variety of applications on both new build and refurbishment projects, and can be used in cold and inverted roof scenarios.
Hot melt, rubberized bitumen cold roof coating system, suitable for a variety of applications on both new build and refurbishment projects and can be used in cold and inverted roof scenarios.
Bauder Hot Melt Waterproofing is particularly advantageous for protected, inverted, or buried roofs such as green roofs, paved, terraces, podiums, plazas, and car parks. Bauder Hot Melt Waterproofing System can also be specified within Bauder Blue Roof and BioSOLAR situations.
The solution is primarily used for new build projects, but it can also be used in refurbishment situations that require an inverted roof solution. The system is a favourable option when used on insitu and precast concrete structures. Other suitable deck options are masonry, exterior grade plywood, OSB3, composite timber, cement bonded particle board and flat metal sheet.

Preparation | |
Horizontal work | Bauder Polymer Primer.Guidance for specification option: A synthetic rubber-based primer, designed specifically to enhance the adhesion of Bauder Hot Melt Waterproofing to difficult surfaces and speed up the total time of installation due to its quick drying time.
Manufacturer guidanceContact manufacturer to confirm substrate suitability if required. |
Skirtings and vertical work | As 'Horizontal work'. |
Liquid-applied waterproofing | |
Type | Bakor790-11 Hot Melt Rubberized Bitumen, Cold-applied.Guidance for specification option:
|
Reinforcement | Bauder Neoprene flashing to junctions of different substrate materials.Guidance for specification option:
It is also used to bridge cracks above 3 mm in concrete decks and to reinforce and waterproof movement joints.
Bauder Polyester reinforcing to all areas.Guidance for specification option:
Bauder Polyester Reinforcement Sheet should be encapsulated with 790-11 at the end of the working day.
|
Surface protection | AP1.Guidance for specification option: Glass reinforced, modified bitumen, sanded surface bituminous membrane, 1.5 mm thick. Used as an access sheet when bedded into the second layer of the Bakor 790-11 hot melt monolithic system.
PLANT E 42.Guidance for specification option: Heavy duty SBS elastomeric root resistant bitumen capping sheet, 4.2 mm thick. Used as an access/protection sheet to be rolled into the second layer of Bakor790-11 hot melt rubberised bitumen coating while it is hot, to ensure a full bond. The product features chemically treated bitumen to deliver superior root resistance which has been tested and approved by the FLL. The membrane is reinforced with 250 g/m² spunbond polyester fleece to allow the finished product to cope with structural movement without fracture. For use with green roof systems.
AP3.Guidance for specification option: AP3 Protection Board is a pre-fabricated board made from a mixture of fibres saturated with at least 75% bitumen. It is completely waterproof and provides superior impact and abrasion resistance. It is ideal for horizontal and vertical applications. Both sides of the product are smooth surfaced covered both sides by a polyethylene film. The boards should be installed as per specification. Generally loose laid with staggered, sealed 100 mm laps. Laps may need be taped in certain situations using heavy duty bitumen tape.
K4E.Guidance for specification option: High performance, elastomeric bitumen, mineral finished, capping sheet, 4.2 mm thick. Used as an access/protection sheet to be rolled into the second layer of Bakor790-11 hot melt rubberised bitumen coating while it is hot, to ensure a full bond. Expandable graphite fire retardant is also incorporated to reduce spread of flame when used on exposed flashings and the product is available in a choice of colours. Not for use with green roof systems.
K5E FBS.Guidance for specification option: Heavy duty, elastomeric bitumen, mica finished capping sheet, 5 mm thick. Used as an access sheet to be rolled into the second layer of Bakor790-11 hot melt rubberised bitumen coating while it is hot, to ensure a full bond. Its mica finish means that it has no integrated UV protection, therefore only suitable for applications where it will be covered with inverted insulation or hard landscaping such as pavers or promenade tiles. Not for use with green roof systems.
PYE PV 200 S4.Guidance for specification option: High performance, elastomeric bitumen, mica finished capping sheet, 4.2 mm thick. Used as an access sheet to be rolled into the second layer of Bakor790-11 hot melt rubberised bitumen coating while it is hot, to ensure a full bond. Its mica finish means that it has no integrated UV protection, therefore only suitable for applications where it will be covered with hard landscaping such as pavers or promenade tiles. Not for use with green roof systems.

System accessories | Not required.Bauder Aluminium Termination Bar.Guidance for specification option: Natural finish aluminium (25 x 6 mm flat plate) used at upstand details to give protection to the top edge of the waterproofing. Usually covered by a metal/lead counterflashing. It should be restricted to use on upstands where a chase cannot be cut into the wall. Bauder GRP Termination Bar.Guidance for specification option: Black glass reinforced plastic (GRP) alternative to a lead counterflashing for use at upstand details to give protection to the top edge of the waterproofing. It should be restricted to use on upstands where a chase cannot be cut into the wall. Bauder Hot Melt Compact – Vertical Outlet (DN100).Guidance for specification option: A thermally insulated rainwater outlet with vertical spigot designed for use when connecting to conventional gravity drainage systems, giving thermal continuity and excellent flow rate performance. The high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet body. The integrated screw down clamping ring and neoprene gaskets ensure total waterproofing security between the waterproofing system and the outlet. Manufactured as a one-piece rigid polyurethane (PUR) foam body that forms the integral sump and spigot. It is manufactured with pre cast studs to receive the fasteners of the clamping ring. This ensures full mechanical sealing between the outlet unit and the Hot Melt Waterproofing and Protection Sheet. A tough, but lightweight, polyamide domical leaf grille permits free flow of water, whilst preventing leaf litter or other debris from entering the outlet. This push fit grille is easily removed to allow for maintenance. A core hole of 250 mm diameter must be cut in the roof deck to accommodate the outlet. In all cases, during installation, the outlet body must be mechanically fixed to the deck. Hot Melt Compact – Insulated Vertical Outlets are suitable for connection to:
Flow rate figures (where applicable) are based on BS EN 12056:3:2000, typically taken using a 35 mm header of water including leaf grille, which for the Hot Melt Compact – Insulated Vertical Outlet gives a flow rate performance of 6.1 L/s. BauderSOLAR F Photovoltaic Mounting System.Guidance for specification option: Flat roof PV mounting solution for framed solar modules. The mounting units are secured to the roof using a membrane-to-membrane welding technique. This installation method means that the roof is not compromised by penetrations for fixings nor is it ballasted, which would add additional weight loading to the roof. Specifically designed to be installed on Bauder bituminous or single ply waterproofing systems and provide a lightweight, low risk and quick to install mounting solution for framed solar modules. Note: For cold roofs only, when used with Bakor790-11 Hot Melt Rubberized Bitumen Roof Coating System. Bauder rooflights/ glazing/ ventilation.Guidance for specification option: All these glazing products are fully compatible with the roof waterproofing systems. Consult manufacturer for details and insert requirements.
Landscaping/ Ballast options.Guidance for specification option: Consult manufacturer for further details. |
