ACTFLEX AT-MESH is the reinforcement specified in ACTFLEX 988 CWP systems for basements, retaining walls, lift pits, swimming pools and water tanks. Pressed into the wet membrane to full saturation and overlapped at least 50 mm, it is fully encapsulated by the following coats, reinforcing the film at FLEXIPLUG coves, PVC panel joints and floor-to-wall transitions. In three-coat below-ground and water-retaining builds it is embedded across the surface for a reinforced 1.5 mm DFT system. Install it strictly to the host membrane's TDS; AT-MESH reinforces the membrane and is not a waterproofing layer on its own.
