Challenges of below grade waterproofing.

Below grade waterproofing is a standout challenge for any construction project. 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 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 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.

Overview

Protect your building with a three-layer membrane

Comprised of a robust HDPE film, pressure sensitive adhesive and protective coating, the PREPRUFE® system forms a robust, permanent and aggressive adhesive bond with any concrete slab. The PREPRUFE® waterproofing system 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 the PREPRUFE® system to form a continuous unbroken seal with the concrete for the design life of the project.

A proven, reliable waterproofing solution for critical applications

The PREPRUFE® waterproofing Advanced Bond Technology™ creates a continuous, integral and permanent adhesive bond to concrete. This seal prevents the lateral migration of water into and around the structure and provides performance for the lifetime of the structure. In the case of a breach or installation error, this fully-bonded membrane ensures that water under hydrostatic pressure is unable to migrate between the membrane and concrete, therefore limiting the risk of catastrophic waterproofing failure. Independent testing and a 25+ year track record has proven that the PREPRUFE® membrane can resist lateral water migration at extremely high pressure – 70+ meters of hydrostatic head pressure. For this reason, the PREPRUFE® systems are globally proven 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, the PREPRUFE® Plus membrane can be applied with a minimal crew and requires no special equipment for installation. Installation is simple: a "kick-out" design allows workers to unroll a sheet in seconds. A dual adhesive ZipLap™ seam allows sheets to bond to one another easily, and the adhesive 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, the PREPRUFE® system has been proven the world over in critical applications. Over the last 25 years, builders have installed more than 650 million square feet (over 60 million m2) of the PREPRUFE® membrane in below-grade applications—there’s hardly a more trusted brand in waterproofing.
