EPD
Certificate type
Hot melt rubberised bitumen formulation.
Application
Used as a waterproofing and roofing membrane on horizontal and vertical surfaces. Suitable for protected roof membrane assemblies, podium and terrace decks, planters, blue roofs, highway bridge decks, underground parking, ramps, railway bridge decks, parking decks, tunnels, reflective pools.
It is the primary waterproofing layer in the following conditions:
- Inverted Roofs protected by pavers, ballast, decking.
- Decks to falls or zero falls.
- Intensive, Extensive, Brown and Biodiverse Green Roofs.
- Blue Roofs.
Must be protected by the appropriate access/ protection layer. Not
intended for use as a permanently exposed surface without the appropriate protection layer, although will tolerate incidental foot traffic, light rubber wheeled traffic until surfacing/ landscaping is installed.
Description
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.
Characteristics of the system:
- Monolithic waterproofing system – no laps
- 100% bond to deck surface
- Lasts the lifetime of the roof
- Safe2Torch complaint detailing on or near combustible construction materials
- Prominent guarantee packages to meet project needs.
- System variations available to the specifier so that a tailored solution meets the needs of the building.
Verified properties:
- CCPI Verification 0007700044/1225: this systems CCPI mark provides accuracy of data delivering assurance to specifiers.
- BBA Certificate 06/4350
- Our BBA certified (06/4350) hot melt waterproofing remains the same independent of the choice of insulation or surfacing on the project.
- Fire testing to BROOF(t4) for external fire exposure on defined permutations of product build up.
- Suitable for zero falls (no back falls) on the structure.
- Its durability under normal service conditions will provide a durable waterproofing for the service life of the roof in which it is incorporated.
- Seamless application provides monolithic waterproofing.
- Full adhesion to deck restricts lateral water movement.
- EPD Certification: Bakor 790-11, Bitumen Membranes.
