An integral, dry powder admixture, Krystol Internal Membrane (KIM) turns an entire concrete mass into a waterproof barrier. When combined with water, KIM’s proprietary chemicals react to form millions of needle-like crystals. The company has developed three versions: KIM-HS for common applications, compatible plasticizers, accelerators, retarders and air-entrainers; KIM-AE, designed for concrete requiring air-entrainment to resist freezing and thawing cycles; and, KIM-ES, designed for use in hot climates and mass concrete. – Kryton International, 800/267-8280; www.kryton.com
