Description

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.


Features and benefits:

  • Suitable for inverted roof, warm roof, green roof, blue roof and exposed pedestrian traffic applications (BBA certified).
  • BBA Certified 25 years – Certificate no. 18-5574.
  • Highest European fire rating BROOF(t4).
  • Cold installed seamless membrane – no lap-joints.
  • Rapid cure/installation.
  • Same day return to full service may be achieved.
  • Low/high temperature application (3°C to +30°C).
  • Awkward details are easily dealt with.
  • UV stable and colour-fast.
  • Resilient to crack bridging up to < 0.5 mm.
  • Exceptional wear and waterproofing qualities provide a durable system.
  • Waterproof, UV stable, seamless and resistant to diluted acids and alkalis, oil, petrol, diesel, vegetable oils and fruit acids.
  • Range of colours available.

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.
