CICO CRYSTALSEAL cementitious Composite coating system based on cement and special additive. These additives penetrate into the concrete and seal the pores and micro fine cracks. This crystalline growth is highly resistant to extreme water pressure from either side of the concrete and also to most aggressive chemicals. Since the process is catalytic, the crystalline structure can reactivate many years after the original application, to seal or re-seal many defects which might occur in the concrete at a later time.
