Description
Krystol Internal Membrane or KIM is an integral crystalline concrete waterproofing admixture; and a PRAH (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.
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.
