Integrally Waterproofing Admixture for Concrete Structures


Product Description

WPA AP8 is an innovative liquid admixture that significantly reduces the permeability of concrete, delivering concrete with ultra-low absorption. By uniquely combining water repellence and shrinkage reduction technologies, WPA provides a hydrophobic and pore blocking system together with a proven and award-winning chemistry that reduces the surface tension of the menisci in the millions of pores in hardened concrete, thus reducing shrinkage strain.
