Make concrete really waterproof
If you are working on reinforced concrete tanking, foundations or works below the ground such as basement, tunnels, bridge and footings where defending your installation from water ingress is crucial, choosing the right waterproofing can prevent leakages.
When contact with water, integral waterproofing generates non-soluble crystal throughout the capillaries and pores in the concrete structure creating an impenetrable water barrier to block water passage from positive (exterior) side, negative (interior) side or from within the concrete itself.

Instant waterproof adhesion to almost any surface
