BETOSIL Concrete waterproofing admixture with crystalline action in powder form. The special active chemicals contained react with the by-products of cement hydration, causing a catalytic reaction and generating an insoluble crystalline formation that fills any pores including small capillary cracks. This process creates a water tight concrete which is always active, since a new reaction will be cause if water or moisture enters any capillary cracks. High endurance in both positive and negative hydrostatic pressure Continuous protection of the structure from water penetration High endurance in chemicals Improves concrete durability Significant reduction of water absorption via hairline cracks Datasheet Gallery ‹ ›
