Krystol Internal Membrane™ (KIM®) (K-301)

Waterproofing admixture for concrete

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 attacks and corrosion of reinforcing steel.
