Krystol Internal Membrane Kim, Packaging Type: Resealable Pails

Krystol Internal Membrane or KIM is an integral crystalline concrete waterproofing admixture; and a PRAH (Permeability Reducing Admixture Hydrostatic Conditions). When combined with water, KIMs proprietary chemicals react to form millions of needle-like crystals. These crystals grow and fill the capillary pores and micro-cracks in the concrete, blocking the flow of water. As time passes and stresses form new cracks, any incoming moisture causes the crystals to reactivate ensuring continuous waterproofing over the years.KIM is simply added to the concrete during mixing at the plant or on-site. Once mixed, it becomes an integral part of the concrete and no extra labour is required for handling or usage. It is compatible with most superplasticizers.
