KRYSTOL INTERNAL MEMBRANE™ (KIM®)
Krystol Internal Membrane™ (KIM®) is a hydrophilic crystalline admixture used to create permanently waterproof concrete. When added to concrete, KIM chemically reacts with water and un-hydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring self-sealing, permanent waterproofing protection.

Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring self-sealing, permanent waterproofing protection. 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.
KIM® lowers the permeability of concrete and can be used in place of labor-intensive waterproofing membranes.
