Dam Covers
DDT Liners supplies and installs Floating Covers for Evaporation Control as well for Containment Purposes.
Evaporation Control
Stored 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 full

- 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.

Typically these types will need supplementary buoyancy to be added, and some means (eg. pumps) to decant rainwater from the cover.
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.
