TechCrete® 2500 Waterproofing System for Concrete is an award winning, bio-based waterproofing system that employs a sodium silicate waterproofing agent, that is enzymatically modified to chemically bond with concrete. With the introduction of water, the
waterproofing 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 the cracks,
pores, and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.
TechCrete 2500 Waterproofing Agent once reactive within the concrete will seal existing cracks up to 5/64” (2.0 mm) in width and will seal future cracks, up to 1/64” (0.4 mm). In the matrix, the product remains reactive when in contact with water, to provide autogenous repairing properties to future hairline cracks.
