PREPRUFE® Membrane Pre-Applied Waterproofing Solutions
High-performance, fully adhered, pre-applied waterproofing system for critical below-grade applications.
Challenges of below-grade waterproofing.
The PREPRUFE® Waterproofing Membrane system utilizes GCP Applied Technologies’ (“GCP”) Advanced Bond Technology to create a continuous, integral adhesive bond to poured in place concrete. 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 any number of ways that water can travel into and around a structure.
- Water can come up through the seams of a poorly designed or improperly installed waterproofing membrane
- Job site conditions such as dust can spoil the adhesion of a membrane to concrete and prevent a system from performing as designed
- Imperfections, voids and cracks in concrete can create a pathway for water to migrate in and around a structure.
To manage the risks outlined above and meet the challenges of below-grade construction, a robust, high-performing and easily installed waterproofing system is required.

Protect your structure with a proven waterproofing membrane
Comprised of a robust HDPE film, pressure-sensitive adhesive and protective coating, PREPRUFE® Membranes form a robust, permanent and aggressive adhesive bond with any concrete slab. PREPRUFE® Membrane products are specifically designed to perform in critical applications and incorporate Advanced Bond Technology™ to ensure fully adhered and long-lasting product performance. This technology allows PREPRUFE® Membranes to form a continuous unbroken seal with the concrete for the design life of the project.
A proven, reliable waterproofing solution for critical applications
PREPRUFE® Waterproofing Membranes Advanced Bond Technology™ creates a continuous, integral adhesive bond to poured concrete. This adhesive seal is specifically designed to prevent the lateral migration of water into and around the structure and provides performance for the lifetime of the structure. Standard ASTM hydrostatic head testing demonstrates that in the case of a puncture ,this fully bonded membrane can successfully prevent water from migrating between the membrane and concrete, greatly reducing the risk of catastrophic waterproofing failure. Independent testing and a 25+ year track record has proven that PREPRUFE® Waterproofing Membranes can resist lateral water migration at extremely high pressure and has been successfully tested at 70 meters of hydrostatic head pressure. For this reason, PREPRUFE® Waterproofing Membrane systems have been proven to perform globally in the world's most critical applications.
Contractor friendly, straightforward installation to ensure performance and accelerate project schedules
Many systems in the market today require the use of welding or mechanically fastened laps. These installation requirements require a skilled installer, introduce risk to the installation and take time, effort and expertise. These methods requires a large crew and specialised equipment in addition to creating the potential for dangerous and unpleasant site conditions such as odour. In addition to the logistical challenges, these processes tend to be finicky— common jobsite challenges such as dust and moisture can easily result in incorrectly completed laps and details, both of which may result in expensive and costly long-term consequences.
By contrast, PREPRUFE® PLUS Membranes can be applied with a small crew and requires no special equipment for installation. Membrane installation is simple: a "kick-out" design allows workers to unroll a sheet in seconds. With PREPRUFE® R Plus Membranes, the dual adhesive ZIPLAP™ seam allows sheets to bond to one another easily, and is designed to resist common nuisance conditions onsite - dust, debris and moisture.
World-quality waterproofing
With applications on mega projects such as the Alaskan Viaduct, the largest bored tunnel on Earth, PREPRUFE® Waterproofing Membranes have been proven the world over in critical applications. Over the last 25 years, builders have installed more than 650 million square feet of PREPRUFE® Waterproofing Membranes. For below-grade applications—there’s PREPRUFE® Membranes have earned the reputation as the most reliable and trusted brand in waterproofing.
