Liquid-applied roof waterproofing system for use on exposed, protected, inverted flat roofs, green roofs, blue roofs, podiums, balconies and walkways.
Suitable for:
Note: A wet electronic leak test is required for all inverted/ buried systems prior to the liquid applied membrane being covered.
Suitable substrates:
Note: Some surfaces may require priming or sacrificial layers.
Pro-BW® Plus is a high performance, hard wearing, fast curing, two-pack* liquid applied membrane for exposed, protected, inverted flat roofs, green roofs, blue roofs, podiums, balconies and walkways. It is designed to provide a durable, monolithic, waterproof liquid applied membrane.
Pro-BW® Plus is cold applied and suitable for refurbishment and new-build projects, reducing installation time from days to hours. Pro-BW® Plus can be installed with a slip resistant surface for pedestrian trafficable decks.
*In colder temperatures an additional accelerator is required.
When subjected to normal service conditions, Pro-BW® Plus liquid applied membrane will provide an effective waterproof barrier up to 10, 15, 20 and 25 years dependent on system.

Recyclability | In most cases, the Pro-BW® Plus membrane is designed to last until the building is taken down, since it can be readily retrofitted at the end of its lifespan, either with a new waterproofing solution or as a component of a thermal improvement. Upon the building's demolition, the membrane will be managed with the substrate onto which it is applied; it could therefore either be recovered for use as aggregate or disposed as mixed material. |
