GCP introduced the PREPRUFE 800PA post-applied membrane, a self-adhered waterproofing membrane for basement walls in open excavation. This new product offers many advantages, including aggressive adhesion, superior performance and a fully bonded watertight seal. PREPRUFE 800PA post-applied waterproofing membrane works seamlessly with PREPRUFE pre-applied membranes to create a complete, fully integrated system for below-grade waterproofing.
In below-grade construction there are many challenges when it comes to managing water. Poorly designed or improperly installed waterproofing membranes are critical factors that may allow water to penetrate the foundation. Jobsite conditions, such as dust and water, can compromise the adhesion of the membrane to concrete and prevent a below-grade application from performing as designed. Additionally, cracks in the concrete create a pathway for water to migrate in and around the structure.
