TamSeal 7


TamSeal 7 is a modified silicate product which acts as a waterproofing solution when applied to concrete. It can improve surface properties such as hardness, permeability, chemical durability and abrasion resistance. It reacts with free calcium in the cured concrete matrix to form a water-insoluble calcium silicate hydrate. This forms a permanent waterproof barrier by penetrating cracks and pores within the concrete substrate.

Permanently seals cracks up to 2.0 mm
