alcan-gove-geotank-pano-3-698-x-222DDT Liners supplies and installs Floating Covers for Evaporation Control as well for Containment Purposes.


Evaporation Control

sas-pastoral-fixed-698-x-472Stored water losses from evaporation can total as much as 2 to 2.5 metres depth per year, in many of Australia’s irrigation areas.

Independent testing has shown that evaporation can be reduced by 95% for every m2 covered by Evap Cap.

Other features of Evap Cap:

  • Best installed when pond/dam is full, or nearly fulle-vap-cap-cover-prefab-roll-698-x-338
  • Reduces algae significantly
  • Automatically “harvests” rainfall
  • Reduces build-up of salinity
  • Reduces wave-action caused bank erosion
  • Australian made for Australian (high UV) conditions
  • Warranty 5 years (or up to 10 years for the thicker version).

Non-Bubble Floating Covers.


HDPE, LDPE, and PP (reinforced, or unreinforced) are regularly used for floating covers – for evaporation control and/ or for containment purposes.

Non-bubble floating covers are usually installed with the pond empty, but DDT Liners have plenty of experience in building/installing covers on already full ponds.
