Waterproofing
Waterproofing covers a wide range of substrates and use cases, and the right system depends on what gets wet. This collection groups our waterproofing-grade products across the catalog so contractors can compare options in one place.
For deep dives by surface type, visit the focused sister collections: Concrete Waterproofing (walls, foundations, roof decks), Waterproofing Wood Decks (plywood and walkable surfaces), Liquid Roof Membrane (full HydroStop restore systems), and the Roof Coating collection for ponding-resistant silicone.
Featured products in this collection include the GAF Premium Acrylic HydroStop system (Miami-Dade NOA 21-0105.10, HVHZ-approved), HydroStop BarrierGuard (NSF ANSI 61 certified for cistern linings and rainwater catchment), Surface Seal SB (thermoplastic rubber for below-grade and balcony waterproofing), and the GAF Silicone line for ponding-water conditions.
