ACTFLEX 989 CWP is a Class III two-part flexible cementitious modified acrylic polymer waterproofing system engineered for internal and external wet areas, under-tile anti-efflorescence barriers, below-grade retaining walls and PVC panel protection. When applied directly to substrate, the cured membrane withstands 250kPa of hydrostatic pressure (25m head of water). Compliant with AS4858-2004 and AS4654.1:2012.
