Pond Liner Installation at Aqua Gardening
The following pictures show the process of pond liner installation for a pond built with sleepers above ground. The sleepers are 40x200mm in 2.4m lengths picked from the pile at Bunnings for around $11 each.

Sleepers finished and ready for weedmat to be laid
Weedmat is laid to protect from plants coming through the base of the pond and puncturing the pond liner.
The weedmat should come up the edges about 20cm.
Sand is laid around the edges of the pond to soften them and make a smoother surface for the pond liner.
A good quality geofabric is then placed on the sand to provide a soft base for the pond liner to absorb impacts from the surface of the pond liner, and to allow water to flow between the surfaces.
The geofabric should cover the area under the pond liner which will be flooded with water.
Next, place your pond liner into position and grip it in place ready to be screwed into the timber.
Bricks carefully placed can also help get the shape of the pond liner right.
