Bauder Bakor 790-11 Hot Melt Rubberized Bitumen Roof Coating System Cold Roof System

As 'Horizontal work'.

Bakor790-11 Hot Melt Rubberized Bitumen, Cold-applied.

Guidance for specification option:

• Bakor 790-11 is poured hot onto the deck and spread by a rubber bladed squeegee in two layers, at an average thickness of 3 mm nominal for each layer, sandwiching spun bond Bauder Polyester Reinforcement Sheet, to form a monolithic membrane with nominal 6 mm thickness.
• Application in two layers increases the membranes crack bridging performance, and it can cope with a wider variety of substrate conditions.
• The hot semi-liquid form of the Bakor 790-11 enables it to infill and cover every crack and deviation in the deck, to form a very strong 100% bond with the deck. This eliminates the possibility of water being able to track beneath the membrane in the event of mechanical damage. It bonds to sound concrete, brickwork or steel and readily conforms to any surface irregularities, protrusions, corners etc.
• Bakor 790-11 contains no solvents. There is therefore no curing period; the system is ready immediately to accept whatever surfacing has been specified.
• It has excellent low-temperature flexibility and bonding characteristics and can be applied in temperatures down to -18°C on to a clean, dry, frost-free surface.

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:

• 110 mm uPVC “O” ring socketed soil grade pipe to BS 4514: 1983.
• Socketed and socket-less cast iron pipework to BS 416:1973 and EN 887.
• Socketed pipework will require cold caulking or PVC to cast iron adaptors. Socketless pipework can be connected using an appropriate SML mechanical coupling.
• PE-HD pipework with appropriate SML mechanical coupling BS EN 12056-3:2000 Flow rates (L/s).

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.
