Waterproofing Basements

Basement waterproofing protects habitable interior space from water intrusion driven by soil moisture, hydrostatic pressure, and water-table rise. The headline product for this use is HydroStop BarrierGuard Waterproofing, a cementitious membrane mixed with water and Portland cement that cures into a hard-wearing, flexible compound with excellent resistance to standing water. Approved for foundation walls, basements, masonry shrubbery boxes, and any concrete or masonry assembly that needs to stop water from migrating through.

Reinforce BarrierGuard with HydroStop Fabric, a 100% polyester layer that bridges hairline cracks and adds tensile strength to the cured membrane. For exterior foundation waterproofing (the other side of the same wall), see Waterproofing Foundations. For potable water storage, see Cistern Waterproofing. Broader category at Concrete Waterproofing. Factory-direct from a GAF-authorized distributor.
