MiraFlex Membrane C is a state-of-the-art, two-component, polymer-modified, highly flexible, cementitious membrane for the waterproofing and protection of concrete, masonry and many other types of construction materials and substrates.  Designed for exterior or interior applications, above or belowgrade, MiraFlex Membrance C can be used and applied to horizontal, vertical and overhead surfaces.

Applied by roller, trowel, spray apparatus or squeegee, MiraFlex Membrane C is ideal for use in waterproofing applications under tile and other composite flooring systems.  It is also capable of stand-alone applications, and can remain exposed to mechanical wear and abrasion, impact, immersion in water, UV and normal climatic and environmental elements.  For detailing and treatment of cracks and construction joints, it can b embedded with Miracote Poly Fabric ffor reinforcement and enhanced dimensional stability.  With its cementitious backbone, MiraFlex Membrane C is compatible with other cementitious materials, thin-set mortars and moist coatings and sealers.
