​GCP's Preprufe® waterproofing systems allow architects and engineers to innovate and make the best use of underground space whether for commercial, business, residential, leisure or other activity. Long proven in climates around the world, Preprufe® waterproofing systems are available with expert technical support from the planning stage of your project right through to onsite installation.

Preprufe® waterproofing systems are designed for high performance to protect underground slabs and blind side applications. Our standards meet or exceed construction standards across the globe. Installation is safe, fast and easy for contractors and applicators avoiding costly project delays. 

Preprufe® Plus waterproofing membrane, with unique ZipLap™technology, is GCP's newest below ground waterproofing system. The durable and conforming membrane tightly seals highly complex slab and blind side details even in the harshest climates and most challenging site conditions. Robust adhesive Ziplap™ layers aggressively protect seams from more than 70m water pressure*. The non-absorbent membrane is easy to use with only two operatives, resists contamination, withstands up to 8 weeks of UV exposure onsite, and is immediately trafficable after application allowing rebar to be installed the same day.

Industry leading architects and engineers use Preprufe® waterproofing solutions worldwide for big and small projects including hotels, museums, hospitals, airports, railways, libraries, underpasses, car parks, tunnels, government buildings, industrial plants, stadiums, shopping malls and residential buildings (include images of iconic big/small projects).
