If water is leaking through existing masonry or you need to protect new construction, DRYLOK® Extreme Masonry Waterproofer’s proprietary formula is GUARANTEED to stop water.
Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK® Extreme Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.
Waterproof interior, exterior, above or below grade walls including basements, retaining walls, and bare concrete swimming pools, foundations, and more.
