IQ FLEXIBOND CWS crystalline capillary waterproofing system contains proprietary blend of Portland cement, quartz aggregate and special chemicals. In the presence of moisture, the active chemicals in IQ FLEXIBOND CWS crystalline waterproofing system penetrates concrete and react chemically with free lime to produce insoluble crystals.
This crystalline growth reduces porosity by blocking capillaries and filling hairline nonstructural cracks (up to 0.25mm wide) caused by shrinkage or expansion.
