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

Our Foundation Series of products is a highly versatile line of eco-friendly, cold-applied liquid membranes designed for air and vapor barrier applications, including cavity wall and masonry wall constructions, new construction restoration, and permeable wall assembly applications, and can be applied directly onto green concrete with as few as two installers.

AIR VAPOUR VARRIER

NaturaSeal&rsquo;s Vapour-Permeable Barriers allows moisture vapour to escape from the wall assembly while preventing air infiltration and liquid water penetration. They are commonly used in assemblies that require drying capability, helping to reduce the risk of trapped moisture and mold development. Typical applications include commercial or residential developments of mid to high rise statures, and passive homes.

Permeable Water Resistive Barrier

NaturaSeal&rsquo;s Vapour-Impermeable Barriers prevents both air and vapour transmission, creating a complete moisture block. These systems are ideal for environments with high humidity, cold climates, or assemblies requiring maximum vapour resistance to protect interior finishes and structural components. Typical applications include commercial or residential developments of mid to high rise statures.
