Imperméabilisation des fondations

Pre-applied waterproofing also referred to as blindside waterproofing, is installed overtop of shoring substrates, creating a strong mechanical bond with the concrete as it cures to form an integral waterproof barrier. These systems are typically used in below-grade applications such as raft slabs, blindside walls, and tunnels where external access is limited after construction. By forming a continuous seal that prevents water migration, pre-applied waterproofing ensures long-lasting protection for structures exposed to hydrostatic pressure or challenging site conditions.
