- Building elements in Wet Areas to be Waterproof or Water Resistant to NCC Specification 26, NCC Part 10.2, & AS 3740
- Backing rod, tape, or sealant should be installed when the membrane is bonded to the substrate
- Type depending on membrane flexibility classAS 3740:2021, 4.10
Class I Membrane (low extensibility)
- Resin systems, or water-based epoxies membranes
- ≥ 6mm ØAS 3740:2021, 4.13.2.2 backing rod should be installed to allow the membranes to flex instead of stretch, with a continuous tape between backing rod and membrane to keep it in place
Class II Membrane (medium extensibility)
- Acrylic membranes, bitumen-based emulsions or mastics membranes
- Tape to allow the membrane to stretch
Class III Membrane (high extensibility)
- Polyurethane, PVC, rubber, or EPDM membrane
- Fillet or sealant to allow even thickness to the membrane
