Construction Chemicals Crystal Sealer



A cement-based, waterproofing compound that chemically reacts with moist cement-based substrates. Crystal Sealer forms insoluble crystals in the capillary tracts of the substrate, permanently waterproofing the surface yet still allowing the surface to breathe.

Product Description


Waterproofing of cement-based surfaces, i.e., cement block, cement render and concrete floors, in domestic, commercial and civil constructions, foundation walls, concrete block walls in warehouses and domestic constructions, tunnels and dams, waterproof barrier between base floor slabs and concrete toppings.


• Penetrates into and becomes a permanent integral part of the surface, therefore it can not peel or blister off as do normal coatings. • Will not tear or puncture and does not have to be protected from back fill. • Being a cement based material, Crystal Sealer has an expansion and contraction the same as the cement surface to which it is applied. • Crystals can grow up to 0.4 metres into the concrete in the presence of water. Crystals grow approx. 1cm depth per week.
