Kryton Internal Membrane (KIM-HS) Kryton Internal Membrane is a cementitious chemical admixture added to fresh concrete and other materials containing Portland cement. It substantially reduces the permeability of concrete, providing permanent waterproof protection for the life of the concrete. How It Works KIM provides maximum waterproof protection by forming crystals throughout the concrete. The chemicals lie dormant until water activates crystal growth, blocking the flow of water through the concrete. Using KIM eliminates the need to use conventional waterproofing membranes by protecting the concrete from the inside out. Where It's Used KIM is used to waterproof new concrete construction projects. It is compatible with most supplementary cementing materials (SCMs) such as superplasticizers and accelerators. It can used in concrete mixes containing fly ash, silica fume and slag cement - all with excellent results. Packaging: 25kg/pail |
