Krystol Internal Membrane (KIM)
Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
KIM lowers the permeability of concrete, and is used in place of surface applied waterproofing membranes.
By stopping the transmission of water through concrete, KIM adds durability and longevity to concrete by protecting it
against chemical attack and corrosion of reinforcing steel.
