The basic idea behind crystalline waterproofing is to prevent the movement of water through the concrete by plugging of blocking the natural pores, capillaries and micro cracks found in all concrete. This stands in contrast to more conventional means of waterproofing, which usually involves applying a coating or membrane to the concrete surface, but is sometime also attempted through densification of the concrete. When added or applied to concrete, crystalline chemicals create a reaction that causes long, narrow crystals to form and fill the pores, capillaries and hairline cracks of the concrete. As long as moisture remains present, crystals continue to grow throughout the concrete. Once the concrete has cured and dried, the crystalline chemicals sit dormant until another dose of water (such as through a new crack) causes the chemical reaction to begin again and grow crystals to shut off the water.
