Installation Guide
Installation of Ausdrain Modules and Filter Fabric is both fast and simple. Pallet sized panels of interlocked modules can be pre-assembled and delivered to site, saving valuable time and labour on large scale projects. The modules can be easily interlocked on-site for use in vertical applications.

Installation
- Place standard modules or panels over the surface of the membrane and butt together (interlocking is not required). For additional protection, a layer of filter fabric under the modules is recommended. Pipe outlets must not be covered with filter fabric.
- Cut module’s at the perimeter to size using a hand or circular saw.
- Roll out filter fabric over the modules allowing for a 150mm overlap at each seam, also allow for additional fabric to cushion the edges of the modules around the perimeter against the waterproof membrane and side of walls.
- Install Walldrain Panels to the walls of planter boxes if required.
- Secure all seams with adhesive tape as an added precaution.
- Lay a 50-100mm layer of washed coarse river sand to create a filtration layer and prevent clogging of the filter fabric (small machinery recommended).
- Lay the soil profile with at least a 300mm depth before allowing heavy machinery over the surface.
