The capillary crystalline waterproofing reacts in the presence of moisture to form a permanent, non-soluble crystalline structure that grows deep within a concrete mass filling its pores, hairline or micro cracks and capillary tracts to make it waterproof. In the absence of moisture, the crystalline components will lie dormant indefinitely. Should moisture become present at any time, the chemical reaction or healing process starts and will repeat itself automatically and advances even more deeply into the concrete and to the source of the water ingress.
