CRYSTOFEX is a cementitious, brush applied, waterproofing treatment for concrete. When it is mixed with water & applied to concrete, it penetrates into the concrete mass protecting against the passage of water.

CRYSTOFEX react chemically to form billions of needle like crystals which blocks the pores, voids & micro cracks in concrete. Pre saturation & subsequent re- wetting of the surface will cause deeper diffusion of the organic chemicals & formation of crystals at greater depth. It may take from seven days to one month to reach its maximum waterproofing capability, depending on the thickness of concrete. Environmental factors such as ambient temperature, density of concrete, moisture present & weather conditions all can effect the timing of sealing process. Under dry conditions,

CRYSTOFEX lies dormant. However it becomes reactive whenever it is re-exposed to moisture.

CRYSTOFEX contains active waterproofing chemicals which react with moisture and unhydrated cement in the concrete, creating insoluble CRYSTOFEX complexes which seal the capillaries and minor shrinkage cracks. They penetrate even against strong hydrostatic pressure, becoming an integral part of the concrete. The waterproofing chemicals remain active for the life of the structure, permanently sealing it from water penetration.
