CWS Fastplug
For intense leaks that was away repair materials
Sometimes the leaking water is so much that no repair material can be used, as water washes it away. In these cases, CWS Fastplug™ is the solution you are looking for. Instantly plug and stop the flow of water through holes, cracks or other openings in your masonry or concrete walls, with this fast-setting hydraulic mortar.
This non-shrinking cementitious product, made of cement and other proprietary chemicals, will work with various concrete substrates and will harden and set in a matter of a few minutes (3-5’ subject to ambient temperature).
