Contec C1 – permanent waterproofing of concrete

Contec crystallising waterproofing compound is an intelligent, self-sealing waterproofing system that transforms porous concrete into a permanent, water-resistant barrier. The system provides a structural defence against water damage and steel reinforcement corrosion. When Contec crystallising waterproofing compound is combined with water and concrete, it reacts with the unhydrated cement particles to form millions of needle-like crystals.

Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants.

Contec C1 is a cementitious powder compound used to waterproof concrete. Contec C1 contains chemicals which react with concrete, forming a waterproofing crystalline structure within the pores of the concrete.
