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.

Pre-Applied Waterproofing

Plaza deck waterproofing systems are intended to protect elevated structural slabs, often used as in split-slab or covered membrane applications. These systems create a durable, continuous membrane, designed to prevent water infiltration into occupied spaces below while accommodating structural movement and drainage requirements. Engineered to withstand overburden loads and varying environmental conditions, podium deck waterproofing supports long-term performance, structural integrity, and reliable protection.
