Solid hexagonal tiles that float on the liquid and arrange themselves into a closed cover. For tanks, ponds, lagoons and reservoirs of any shape, in water, wastewater and industrial liquids.
Get a quote Test resultsHexa-Cover® is a patented floating cover made of individual hexagonal tiles. Each tile is moulded from recycled polypropylene and has ribs on both sides. Poured onto a liquid, the tiles spread out and settle edge to edge, covering up to 99% of the surface.
Because the cover is made of loose tiles and not one sheet, it fits round tanks, rectangular basins and irregular ponds equally well, rises and falls with the liquid level, and can be made larger or smaller by adding or removing tiles.
It has been on the market since 2004 and is manufactured by Hexa-Cover A/S of Denmark, with production in the EU, North America and Australia.
less odour. For sewage, industrial wastewater, leachate and slurry.
less emission, such as ammonia from the liquid surface.
less evaporation from stored water.
less algae and organic growth, because sunlight no longer reaches the water.
lower heat flux than an open surface, measured by Aalborg University on R114.
The small tiles deter waterfowl from landing on the covered liquid.
“Up to” figures are the manufacturer’s stated maximums. The test results page shows what was measured, by whom and under which conditions.

The way a floating element is built decides how long it lasts. Hexa-Cover® tiles are solid:
The main points from the manufacturer’s instructions for use, which are written for slurry tanks and lagoons.
Multiply the liquid surface area in m² by 28 for R114 or by 43 for R90. A 1,000 m² pond needs about 28,000 R114 tiles, which is 24 big bags. The quote form calculates this for you.
R114 is the larger and heavier tile: 22.8 cm across and 6.8 kg per m² of cover, against 18.0 cm and 5.2 kg per m² for R90. The independent odour, ammonia and drinking water tests were carried out on R114. We recommend the model for your basin when we quote.
Not if the inlet and outlet openings are smaller than the tile, which is the first thing to check before installation. Pump or draw off from below the surface and keep mixers 1 to 1.5 m from the tiles.
No. It covers up to 99% of the surface, and in practice about 5% stays open along the walls and between tiles. It is not gas-tight and cannot be used to collect biogas.
Recycled polypropylene, moulded as a solid tile. No Freon or other harmful substances are used in production.
The warranty is 10 years and the expected lifetime is 25 years.
With the surface area, the liquid and the location we will recommend the model and prepare a quotation.
