Polyprufe® BSW15 is a high-performance HDPE Blind-Side waterproofing membrane designed for applications where the waterproofing must be laid prior to pouring the concrete. It allows for a fully-bonded waterproofing membrane to be applied to the positive-side of the building structure even where the said surface is inaccessible to application personnel.
Polyprufe® BSW15 is highly resistant to hydrostatic pressure, ground settlement, and soil chemicals. It is also fully mechanically bonded, making it non water-tracking in the unlikely event of damage to the membrane, providing long-term watertight integrity even in the most demanding of applications.
Polyprufe® BSW15 is a pressure-sensitive self-adhesive membrane that allows for watertight sealing of overlapping sheets. It is cold-applied and easily installed in restricted and confined spaces.
