Hexa-Cover

What Hexa-Cover does

Hexa-Cover A/S is a Danish private company founded in 2004 and headquartered in Thisted, Denmark, that designs, patents, and distributes a proprietary line of hexagonal floating cover elements used to suppress evaporation, emissions, odor, algae growth, and heat loss from open liquid surfaces. The core product portfolio consists of two standard models — the R90 (18 cm diagonal, 43 pieces/m²) and the R114 (22.8 cm diagonal, 28 pieces/m²) — manufactured from 100% recycled polypropylene, plus specialized Oil & Gas Duty and API-compliant variants engineered for heavy oil and high-temperature applications. The elements self-distribute on liquid surfaces and adapt automatically to level changes without special equipment, delivering up to 99% surface coverage and up to 95% reduction in evaporation and emissions per company claims.

The company operates an asset-light model: physical production is handled under a strategic manufacturing partnership with Gravenhorst Plast A/S (established November 2015), with a parallel North American manufacturing footprint in Toronto, Canada. Sales are quote-based and project-tied (priced per m² of coverage), distributed through a network of more than 40 regional dealers and distributors spanning Europe, the Americas, Asia Pacific, the Middle East, and Africa, supplemented by direct sales from Danish headquarters and a US subsidiary (Hexa-Cover, Inc., Atlanta, established August 2014). End customers are predominantly municipal water utilities, water and wastewater operators, airports, defense installations, agricultural and biogas operations, and oil and gas producers. Marketing relies on international trade shows (IFAT, Aquatech, EuroTier, ADIPEC, WEFTEC), a multi-language website, downloadable technical and certification documents, and an extensive case-study archive. The company is privately held with 1-10 employees and no disclosed external investors or funding rounds.

Core offering

Hexa-Cover manufactures and supplies patented hexagonal floating cover elements made from recycled polypropylene that are deployed on liquid surfaces across basins, lagoons, reservoirs, ponds, and tanks. The interlocking elements automatically distribute themselves and adapt to changes in liquid level, reducing evaporation, emissions, odors, algae growth, and heat loss for water utilities, industrial facilities, agricultural operations, and oil and gas sites. The company sells its products globally through a dealer network spanning more than 40 countries and through direct sales from its Danish headquarters and North American subsidiary.

Direct peers

• Atarfil: Atarfil is a Spanish-headquartered manufacturer of geomembranes and floating cover systems for water, mining, and environmental containment. It is a direct competitor to Hexa-Cover in floating covers, particularly in European and Latin American markets.
• BTL Liners: BTL Liners installs floating covers, baffle curtains, and geomembranes for municipal wastewater, industrial process water, and stormwater ponds — directly competing with Hexa-Cover in the North American lagoon and reservoir cover market.
• Elastec / American Marine: Elastec manufactures floating environmental equipment including booms, covers, and tank covers for oil spill response and industrial containment. Comparable to Hexa-Cover in floating liquid-surface solutions for industrial and oil & gas customers.
• Layfield Group: Layfield Group manufactures geomembranes and floating cover systems for industrial wastewater, mining, and water reservoir applications — directly competing with Hexa-Cover in floating liquid-surface covers, but offering flexible membrane-style solutions rather than discrete elements.
• Geomembrane Technologies Inc. (GTI): GTI designs and installs floating and modular covers for municipal and industrial wastewater, potable water, and biogas applications. It is a direct competitor in the floating cover category Hexa-Cover serves, with comparable municipal water utility end customers.
• Western Environmental Liner: Western Environmental Liner designs and installs floating covers, baffles, and geomembranes for wastewater lagoons, reservoirs, and industrial ponds — directly competing with Hexa-Cover in the municipal and agricultural water-cover market.
• Industrial & Environmental Concepts (IEC): IEC supplies floating cover and membrane systems for wastewater treatment, industrial process water, and odor/emission control — the same core applications Hexa-Cover targets with its hexagonal elements.

Broad incumbents

• Solmax: Solmax is one of the largest global manufacturers of geosynthetics and geomembranes (including Raven Industries' former products). It serves the same end customers as Hexa-Cover (water utilities, mining, oil & gas) but operates as a broad incumbent across many geosynthetic categories.
• Ovivo: Ovivo is a large global water treatment equipment supplier offering covers and odor-control solutions for municipal and industrial water and wastewater. It competes with Hexa-Cover in the municipal water/wastewater segment but as part of a much broader treatment-equipment portfolio.

Emerging players

• AquaBlok: AquaBlok produces bentonite-based composite materials for sealing and capping sediment, ponds, and lagoons. It addresses overlapping water- and sediment-cover use cases but uses a different (granular composite) technology versus Hexa-Cover's floating PP elements.
