The importance of foundation waterproofing
Leaks from groundwater, storm water runoff or irrigation water may impact the foundation of any building that's improperly waterproofed — and when concrete is involved, there are a number of ways that water can travel into and around a structure.
A continuous waterproofing system is critical to mitigating these risks.
Best-in-class waterproofing performance
With more than one billion ft2 around the globe, PREPRUFE® waterproofing is trusted by architects and contractors the world over. Featuring ease of installation along with robust adhesion between the membrane and the structure, the PREPRUFE® line of products offers premium protection against moisture and gas for the design life of the structure. Our unique ADVANCED BOND TECHNOLOGY™ enables the system to form an aggressive bond with the concrete slab. ASTM hydrostatic head testing demonstrates that this can successfully prevent water from migrating between the membrane and concrete, greatly reducing the risk of catastrophic waterproofing failure.
Contractor-friendly features
Our R&D team continually seeks ways to innovate in ways that help make contractors’ lives easier. The PREPRUFE® line of waterproofing system offers an array range of time-saving features that vastly simplify installation. The ZIPLAP™ seams in PREPRUFE® Plus pre-applied waterproofing systems helps sheets bond to one another more easily, while the two-in-one capabilities of PREPRUFE® 800XP post-applied waterproofing eliminates the need to add a separate protection board. All this adds up to faster ROI for contractors.
Supported by waterproofing experts
Our waterproofing products are backed by end-to-end design and field support to help our customer with everything from product specification to streamlining installation. Many customers rely on PREPRUFE to help accelerate project completion, gain greater peace of mind, and improve the durability of their structure.
