CWS Admix is a crystalline admixture that is added to new concrete during batching to waterproof and protects concrete for the life of the structure.
CWS Admix forms crystals within the pores and capillaries in the concrete, effectively blocking the passage of water and not allowing chlorides and sulfates to reach the rebar and initiate corrosion. It also seals cracks in the concrete up to 0.4mm (1/64″) and will seal future hairline cracks in the presence of moisture.
Versatile: CWS Admix is a crystalline reactive waterproofing compound in powder form, applied as an admixture in fresh concrete, It reacts with calcium, which is contained in cement and water forming millions of insoluble crystals, within the concrete capillaries, blocking the passage of water.
Simple: CWS Admix is effective on all cement systems.
Long Term: After adding to the concrete, CWS Admix stays in the concrete matrix forever. The system effectively blocks the passage of water in concrete by filling the capillaries and micropores of crystalline developments for the entire service life of the structure
CWS Admix features crystalline waterproofing for below ground and water tank applications including:
