PREPRUFE® Plus Pre-Applied Waterproofing Membrane
High performance, durable below ground waterproofing
A proven track record of success
GCP’s flagship PREPRUFE® waterproofing system offers time-tested protection, backed by waterproofing specialists with decades of experience safeguarding the world’s most iconic structures. Our design and field support professionals work side-by-side with architects and applicators to protect foundations and basements in some of the toughest environments.
The PREPRUFE® system has now been used to waterproof more than 222,000 square meters around the world. Building on this success, GCP developed the PREPRUFE® Plus waterproofing membrane system to deliver unparalleled performance and ease of installation. The system provides a high-performance barrier against water and moisture, aggressive soils as well as hazardous gases such as radon and methane.

- Product Name
- Key Benefits
- Applications Type
PREPRUFE® 300R Plus membrane is a unique pre applied composite sheet comprised of a thick HDPE film, pressure sensitive adhesive, and weather resistant protective coating. Designed with ADVANCED BOND TECHNOLOGY™ and dual adhesive ZIPLAP™ seams, the PREPRUFE® Plus membrane forms a unique, integral bond to poured concrete. This integral bond is specifically designed to provide a robust barrier to water, moisture and gas and prevents both the ingress and lateral migration of water.
- Fast, Simple and Secure – engineered for efficient jobsite application and long term waterproofing performance.
- ADVANCED BOND TECHNOLOGY™ reduces risk - develops an intimate and continuous adhesive bond to concrete proven to resist water migration between concrete substrate and the waterproofing membrane.
- PREPRUFE® ZIPLAP™ dual adhesive watertight laps - easy to execute year round even in harsh conditions; laps stay clean and dry until the seal is made.
- Water and vapour proofing for all basement grades to BS 8102:2009 & IS 16471 : 2017
- Waterproofing civil engineering sub-structures.
- Protection of reinforced concrete structures in most aggressive ground exposures including conditions experienced in the Arabian Peninsula.
- Certifications available upon request
Gain proven, long-term protection
With the PREPRUFE® Plus waterproofing membrane, structures can be protected throughout their lifetime. Made of a patented HDPE geomembrane, the PREPRUFE® Plus waterproofing membrane forms an intimate bond with the concrete, helping to prevent costly damage from floods, mold, mildew as well as gas fumes. The membrane also stands up to dirt, foot traffic and UV exposure, preventing it from being damaged before the concrete is poured.
Safeguard your structure
Ensuring structural integrity means not just preventing water ingress but stopping water migration between the membrane and the building. This way even if the waterproofing membrane is accidentally damaged, leaks are confined to a small area and can be easily repaired.
That’s why GCP developed the PREPRUFE® Plus waterproofing membrane with Advanced Bond Technology™. Unlike conventional membranes that have a fleece or mesh interface between the membrane and the concrete, PREPRUFE® Plus waterproofing membranes form an impermeable protective bond directly to the concrete to prevent both water/gas infiltration and to prevent water from migrating between the membrane and the concrete.
Accelerate construction time
Consisting of wide, lightweight rolls, the PREPRUFE® Plus waterproofing membrane reduces the time and cost involved with application. The system is immediately trafficable upon application, so rebar can be installed the same day. Self-adhesive ZIPLAP™ watertight laps make it easy to tightly adhere membrane panels together, without the need for heat, power or special equipment. In addition, complex details can be simplified and tightly sealed by using PREPRUFE® tape and BITUTHENE® LM.
