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 wet area and water-retaining structure waterproofing applications, including fountains and ponds, swimming pools, water-retaining structures, potable water tanks, and storm tanks, and can be applied directly onto green concrete with as few as two installers.&nbsp;

Wet Area & Water Retaining Structure

NaturaSeal&rsquo;s enhanced systems for swimming pools and fountains provide a secure, watertight barrier that prevents water loss and protects the surrounding structure from moisture damage. Designed to withstand constant immersion, movement, and chemical exposure, these systems support the integrity of both the concrete shell and the applied finishes. Effective waterproofing is critical for maintaining performance, reducing maintenance demands, and extending the service life of recreational and decorative water features.

Swimming Pools & Fountains

Interior tank waterproofing is designed to ensure long-term water tightness in structures designed to store or manage storm and potable water. These systems resist water migration and protect the concrete from chemical exposure and deterioration. By forming a robust and seamless membrane, storm water tank waterproofing supports reliable performance across varying water levels and environmental conditions. NaturaSeal&rsquo;s VOC-free systems are the ideal solution for confined spaces.

Storm Water Tank Waterproofing

Cold-applied waterproofing systems for wet areas, fountains, ponds, swimming pools, potable water tanks and water-retaining structures. Durable, seamless and eco-friendly.
