Waterproof Coatings
Elastomeric and crystalline waterproof coating systems applied to building surfaces, concrete structures, and below-grade assemblies.
Coating Systems That Actually Stop Water
Not all coatings marketed as waterproof actually prevent water penetration under sustained hydrostatic pressure. El-Lay specifies coating systems that are appropriate for the actual water exposure condition — elastomeric coatings for exterior facade water management, crystalline reactive technology for below-grade concrete structures, and fluid-applied membranes for horizontal surfaces subject to ponding water and foot traffic.
- Elastomeric coatings for exterior stucco and CMU water management
- Crystalline technology for positive and negative side concrete waterproofing
- Fluid-applied membranes for horizontal decks, planters, and below-grade walls
- All coating applications flood-tested or probe-tested before final acceptance

Substrate-Specific Specification
The correct waterproof coating system depends entirely on the substrate, the direction of water pressure, the exposure conditions, and the required use of the finished surface. We evaluate all of these factors before specifying a product — ensuring the coating system delivers the performance you need rather than just checking a box.

Waterproof Coating Systems
Elastomeric Exterior Coatings
High-build elastomeric coatings for stucco and CMU building exteriors — crack-bridging, water-repellent, and UV-stable. The correct specification for California commercial buildings.
Crystalline Waterproofing
Reactive crystalline technology for below-grade concrete walls and slabs — crystalline deposits grow into the concrete matrix, permanently blocking moisture pathways.
Fluid-Applied Membranes
Spray or trowel-applied seamless membranes for balconies, planters, and below-grade walls — monolithic application with no seams to fail, flood-tested before finish installation.
Traffic Deck Waterproofing
Pedestrian and vehicular traffic-bearing waterproofing systems — elastomeric or polyurethane decks that provide both waterproofing and a finished, slip-resistant walking surface.
