Dam Liners & Covers

Geomembrane Liners for Dams and Ponds

One of the most common geomembrane applications is as a pond liner. Pond liners may be used where:

  • The subgrade conditions do not allow a cut to fill pond to hold water.
  • The subgrade materials are dispersive and this interferes with the end use of the water.
  • Liquids other than pure water are stored and it is required to minimise the escape of the contained liquid. An example of this is sewerage effluent where the entry of small amounts of pollution to subterranean water supplies may have health implications for downstream users.
  • It is required to minimise erosion on the pond embankments. Erosion may be caused by the impact of rain or by the effect of aeration or mixing equipment within the pond. An example of this is the use of lining systems on prawn grow out pond embankments to minimise the entry of suspended sediments into the pond and the associated increased risk of disease and crop loss.
