Floating covers in operation — modular panels on a live lagoon.
Built for operators, not brochures
- 01
Drop-in deployment
Modules are poured from transport bags directly onto the water — no frames, anchors, or specialist crews on site. Patented hexagonal tiles self-align into full coverage within days.
- 02
All-weather durability
Moulded HDPE engineered for decades of UV, ice, wind, and storm exposure with no maintenance cycles. Backed by a written 10-year warranty validated in the field.
- 03
Any basin shape
Modular segments adapt to rectangular, circular, and irregular pond geometries without custom fabrication. From compact treatment channels to multi-hectare lagoons — same tile system.

Questions
- How do covers reduce algae and chemical use?
- By blocking over 99% of sunlight from the water surface, floating covers stop photosynthesis — the primary driver of algal blooms. Operators typically see a sharp drop in algaecide, coagulant, and chlorine demand within the first season. Less chemical dosing means lower operating costs and fewer water-quality compliance issues.
- How much evaporation is prevented?
- Field measurements show evaporation reductions of 80–96%, depending on climate, wind exposure, and basin geometry. The floating layer forms a physical barrier between water and air — cutting water losses, stabilising levels, and reducing the energy needed to maintain process volume in lagoons and reservoirs.
- How do covers protect wildlife?
- A fully covered basin presents a uniform dark surface that birds and other fauna do not recognise as open water. This virtually eliminates casualties from landing, drinking, or becoming trapped on retention ponds, tailings lagoons, and industrial reservoirs — an increasingly common regulatory requirement on active sites.
- What is the typical return on investment?
- Most installations pay back in 3 to 5 years through combined savings: less water make-up from evaporation, lower chemical and energy bills, reduced maintenance, and avoided process downtime. On large basins, payback can be faster when aeration loads and chemical dosing drop sharply after deployment.
- How is installation carried out?
- No on-site assembly is required. Modules are poured directly from standard transport bags onto the water surface. No specialist crews, proprietary frames, or anchoring systems are needed — a single operator can deploy thousands of square metres in one day with no further human intervention.
- How do modules position themselves on the water?
- Once released, each patented hexagonal geometry causes tiles to self-orient and interlock. Wind, currents, and natural movement push them into a tight, gap-free mosaic — typically within days — without manual placement, fastening, or adjustment.
- How long do floating covers last?
- Moulded in HDPE for decades of outdoor service in heat, ice, and UV exposure. Backed by a written 10-year warranty, with scheduled inspections in years 1, 3, and 5.
