Catalyst PWC is a biochemical modified silicate solution that provides long-term waterproofing and durability benefits to concrete. It penetrates into concrete and reacts with free calcium and water to form a water insoluble calcium silicate hydrate gel complex in cracks, pores and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.
Catalyst PWC will seal existing leaking cracks to 2.0mm. In the matrix the product remains active when in contact with water to provide autogenous healing properties to future hairline cracks.
