ACTFLEX 988 CWP Hydrostatic Cementitious Membrane

ACTFLEX 988 CWP is a two-part flexible cementitious waterproofing membrane designed for below-ground, hydrostatic and immersed applications where polyurethane systems are not suitable. It is ideal for basements, retaining walls, water tanks, swimming pools and internal wet areas requiring negative-side tolerance and damp substrate compatibility.

Designed to meet AS 4858 and AS 4654.1 as a Class II membrane, it provides 350kPa hydrostatic pressure resistance and strong adhesion to concrete and masonry. This system requires a minimum two-coat application, or three coats for underground and permanent water contact areas. Not designed for exposed UV or permanent trafficable finishes.
