ACTFLEX 989 CWP
high-performance waterproofing
Class 111 two-part flexible cementitious
ACTFLEX 989 CWP is a high-performance waterproofing system engineered for a wide range of applications, including internal and external wet areas such as bathrooms, balconies, podiums, courtyards, non-exposed rooftops, swimming pools, and under pedestal systems. This two-part flexible cementitious modified acrylic polymer membrane offers exceptional versatility, serving as an under-tile anti-efflorescence barrier, a waterproofing solution for below-grade retaining walls, and protection for PVC panels. Compliant with AS4858-2004 and AS4654.1:2012 standards, it is classified as a Class 111 waterproofing membrane.
