Kryton International Inc.
Kryton Internal Membrane (KIM) crystalline admixture offers a waterproofing solution by turning concrete into a water barrier. When combined with water, the chemicals react to form millions of needle-like crystals within the concrete. These crystals grow and fill the capillary pores and micro-cracks, blocking the passage of water. If minor cracks from in the future and water enters, the chemicals reactivate to form new additional crystals to block the water. www.kryton.com
