​​​​​​​​​​​​​​​​​​​Preprufe® - For ContractorsRequest a​ Free​ ​Project Appra​isal​​​

All projects are unique. Project complexity, size, site, location, climate, timeline and budget are considerations when choosing a waterproofing system that will add value and success to your project.

GCP's Preprufe® waterproofing system with Advanced Bond Technology™ is designed to offer significant value that saves costs and time and provides with peace of mind for projects both large small:

  • ​Proven waterproofing performance for underground slabs and blind side applications with complex details in climates worldwide
  • Safe, easy and fast installation with minimal labour in confined space without the use of heat, power, special equipment or special tools
  • Onsite technical support and best-in-class customer service from the earliest stages of your project through completion


Installed with GCP's unique Advanced Bond Technology™, the 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 or fleece interface between the membrane and concrete, Advanced Bond Technology™ does not risk water migration via capillary action and saves material costs and installation time.

​ ​

Preprufe® Plus waterproofing membrane, with unique ZipLap™ technology, is GCP's newest below ground waterproofing system offering watertight protection in the harshest climates and most challenging site conditions. Robust adhesive Ziplap™ layers aggressively protect seams from more than 70m water pressure*. The wide kick-out roll is liner free reducing storage and waste costs. The patented surface coating is non-absorbent, highly resistant to contaminants, dirt and UV exposure for up to 8 weeks. This new waterproofing system from GCP is immediately trafficable after application allowing rebar to be installed the same day to keep your project moving.
