Dayton Superior Waterstop Hydraulic Cement Repair Mortar, 50-Pound Bucket

Dayton Superior Waterstop is a non-corrosive, non-rusting, extremely fast-setting hydraulic-cement compound for plugging and stopping active water leaks in concrete structures or masonry surfaces. When mixed with water to a thick consistency and hand formed into a plug, it will stop active leaks even under water.

Waterstop is designed to be used to stop water flow through non-moving cracks, crevices and holes in concrete or masonry surfaces. It stops leaks into or out of basement walls, concrete blocks, tubs, swimming pools, concrete pipe, culverts, manholes, elevator pits, and storm drains. Waterstop can be used as a plug for cisterns, sewers, tunnels, mines and dams.
