The Preprufe® 300R Plus waterproofing system delivers exceptional protection and performance through advanced membrane technology and proven adhesion strength. Engineered for below-ground and blindside applications, it provides long-term defence against water ingress, ensuring the integrity of structures for their entire design life.

At the core of the system is ADVANCED BOND TECHNOLOGY™, which forms a robust and permanent bond with freshly poured concrete. This powerful adhesion prevents lateral water migration between the membrane and structure, significantly reducing the risk of waterproofing failure.

Preprufe® 300R Plus is designed for versatility and ease of installation, whether pre-applied before the pour or post-applied to existing concrete. Safe for use on blindside walls and complex foundation designs, Preprufe® 300R Plus offers consistent protection against hydrostatic pressure, providing confidence and flexibility across a wide range of construction conditions.
