Cementitious coatings penetrate and bond into the concrete itself, forming a breathable barrier that resists water under pressure from either side. Both grades are non-toxic and safe for drinking-water storage.
Acrylic-modified cementitious waterproofing coating
A two-part acrylic-modified cementitious coating that protects concrete against water, vapour and chloride ingress. SR Flex cures to a tough, flexible, breathable barrier that resists hydrostatic pressure — and being non-toxic, it is safe for potable water tanks.
