ACTFLEX 988 CWP
two-part flexible cementitious acrylic waterproofing membrane
High-performance, two-part flexible cementitious acrylic waterproofing membrane for positive and negative hydrostatic pressure applications.
ACTFLEX 988 CWP is a two-part flexible cementitious acrylic waterproofing membrane formulated for use in both internal and external wet areas, including below-ground waterproofing, tanks, retaining walls, and swimming pools. The product combines a polymer liquid (Part A) with a reactive powder (Part B) to form a dense, flexible coating resistant to water pressure and efflorescence migration.
Compliant with AS4858-2004 and AS4654.1:2012, ACTFLEX 988 CWP delivers hydrostatic pressure resistance up to 350 kPa (3.5 bar) and elongation of 217%, ensuring durability in submerged and high-pressure environments. It is non-toxic, non-flammable, low VOC, and suitable for both positive and negative side waterproofing.
