Krystol Internal Membrane™ (KIM®)
Create permanently waterproof concrete with Krystol Internal Membrane (KIM) admixture. 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.
