How to have less evaporation and algae growth in a closed basin

When the water basin is completely sealed, the basin is closed. Result: there is less evaporation. Moreover, the stored water heats up less thanks to the reflective layer, says Bas van der Elst of Hendic. And last but not least, there is no algae growth in the basin because the water is covered.

The used foil has its own buoyancy through air chambers in the material. So it doesn't need a system of pipes or floats to make it float. Bas continues: "A pipe system or the use of floats often makes a floating cover vulnerable in strong winds. With the DelafloaT system, the slope protection is welded to the DelafloaT material. A weighting tube rolls along the inside of the slope. This keeps the DelafloaT lie tight and flat on the water."

Hendic has a Mexican dealer (DQ Hortisolucions, Dennis de Zeeuw), and their products are shipped with Dutch companies. Hendic has sent complete basin linings with cover films to Mexico. These were floating covers. In areas like that, a lot of water evaporates, so it's important to conserve all available water. "We sell a lot of Delafloats, especially in warm countries," says Bas.
