How It Works

Krystol Internal Membrane or KIM is an integral crystalline concrete waterproofing admixture; and aPRAH(Permeability Reducing Admixture – Hydrostatic Conditions). When combined with water, KIM’s 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.
