Cement Based Waterproofing Finish

TAMOSEAL FOUNDATION COATING is a cement-based waterproofing material specifically designed to waterproof the exterior surface of below grade concrete and masonry. When properly applied, this formulation becomes an integral part of the wall, filling and sealing the pores and voids in the surface, while remaining breathable. TAMOSEAL FOUNDATION COATING is normally applied to the positive side, but may be applied to the negative side when hydrostatic pressures are low and aesthetics are not important.
