Waterproof, Anti-Fracture Sheet Membrane

Gripset GC2 is part of an innovative sheet membrane system that provides high performance waterproof and vapour proof membrane with outstanding crack resistant de-coupling properties. Specifically designed for external wet areas, roofing and specialised remedial applications.

Consisting of fibre bonded fabric on the exposed face and heavy duty fibre backing on the rear face, GC2 forms a fast and highly durable waterproof system that allows surface toppings/finishes or Gripset trafficable coatings to be applied over immediately after the membrane system has been installed.

A unique feature of the GC2 system is the anti-fracture and decoupling properties to prevent stress cracks from transferring through to the finished surfaces over concrete, masonry and timber substrates. Further details are available in the Gripset GC manual for a range of specifications and fixing details for waterproofing applications where this system can be used.
