The right choice for Safe, Fast and Easy Installation

Preprufe® waterproofing system with Advance Bond Technology is the system of choice for leading specialist installers. Safe, fast and easy to install in confined underground space with complex details and blind side applications, the Preprufe® waterproofing system does not require heat, power, special equipment or special tools.  Wet conditions and variable soil types will not activate the membrane prematurely and it is durable enough to withstand traffic without protection layers saving valuable time. 

Installed with GCP's unique Advanced Bond Technologythe Preprufe® waterproofing membrane aggressively bonds directly to poured concrete forming an impermeable seal between the membrane and structure unlike other systems that require mechanically attaching a mesh interface between the membrane and concrete.

​Preprufe® Plus waterproofing membrane, with unique ZipLap™ technology, is GCP's newest below ground waterproofing system. Robust adhesive Ziplap™ layers aggressively protect seams from more than 70m water pressure.* The kick-out roll requires only two operatives to use and is liner free. The patented surface coating is non-absorbent, highly resistant to contaminants, dirt and UV exposure for up to 8 weeks. It is immediately trafficable after application allowing rebar installation the same day.
