DRYLOK 00917 is a fast-setting hydraulic cement that seals active water leaks in concrete and masonry within 3-5 minutes. It withstands up to 3,050 lbs. of hydrostatic pressure, expands as it dries to lock in place, and anchors metal to masonry without requiring a topcoat. Ideal for interior and exterior repairs, this 4-pound gray powder mixes with water to deliver durable, high-pressure waterproofing for cracks, holes, and mortar joints.
