Polyfab BB

Polyfab BB is a 100mm wide self-adhesive non-woven polyester fabric. It incorporates a self-adhesive portion (central 1/3 of tape) that acts as a bond-breaker over joints, cracks or other areas of movement. When used in conjunction with approved liquid applied waterproofing membranes the combined system will meet the requirements of AS 3740:2005 “Waterproofing of Wet Areas Within Residential Buildings”.
