Description
CretePRO® FasTrac is a bio-based sealer that employs a sodium silicate sealing agent, which is enzymatically modified to chemically bond with concrete. With the introduction of water, the sealing agent increases in mass and forms a gel that encapsulates water trying to enter the concrete. This vapor permeable gel fills cracks, pores, and voids in the concrete, creating a long-term barrier to water infiltration. It penetrates into the concrete and reacts with the calcium and water contained in the concrete, to form a calcium-silicate gel complex that fills cracks, pores, and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.
