It provides total and permanent waterproofing solution to water leakage, ingress or seepage in concrete structures or any cementitious substrates due its unique, surface applied penetrative capillary water proofing system. It works through internal crystallization that seals the pores and hairline cracks in the concretes thus blocking effectively further passage of water. The active chemical in CRESPROOF CC serves as a catalyst to re-activate crystallization process every time water penetrates into the structure through newly formed capillaries therefore ensuring permanent water tightness.
