Hexprotect® SLIM Floating Cover — 99% Coverage at the Most Affordable Price for Tanks & Sheltered Ponds
Hexprotect® SLIM is a lightweight hexagonal floating cover tile designed for sheltered ponds and tanks where wind resistance is not the primary concern. Its patented low-profile design delivers 99% surface coverage for water storage tanks, sheltered agricultural lagoons, and indoor treatment basins — maximum algae suppression and evaporation control at the lowest cost in the AWTT 99% coverage range.

The Problem: High-Performance Covers Cost Too Much for Sheltered Sites
For water storage tanks, enclosed lagoons, agricultural irrigation ponds, and other sheltered liquid containment sites, wind resistance is not the primary concern — but algae control, evaporation reduction, and odor suppression are just as critical as at exposed outdoor sites.
Specifying heavy-duty wind-resistant covers for low-wind applications means paying for performance capabilities you don't need. For budget-conscious operators who need maximum algae and evaporation control in sheltered environments, there has been no optimized solution — until Hexprotect® SLIM.
The Solution: 99% Coverage Optimized for Sheltered Applications
Hexprotect® SLIM was developed through intensive R&D to deliver the maximum surface coverage performance in a low-profile, lightweight tile — removing the cost overhead of wind-resistance features not needed in sheltered environments.
The result is a 99% surface coverage hexagonal tile system that achieves maximum algae suppression, up to 95% evaporation reduction, and effective odor and VOC control at the most affordable price in the AWTT 99% range. Ideal for water storage tanks, enclosed basins, and naturally sheltered lagoons.

Why Hexprotect® SLIM Is the Smart Choice for Sheltered Applications
Maximum coverage performance without paying for wind-resistance overhead you don't need.
Most Affordable 99% Coverage
Hexprotect® SLIM delivers full 99% surface coverage at the lowest cost per square foot of any 99% system in the AWTT range — making maximum algae and evaporation control accessible at budget-constrained projects.
Maximum Algae & UV Suppression
99% surface coverage blocks virtually all sunlight from reaching the liquid surface, providing near-total algae and cyanobacteria suppression without chemical treatment.
Ideal for Tanks & Sheltered Ponds
The SLIM profile and 1 lb/ft² buoyancy are perfectly matched for enclosed or covered tanks, sheltered agricultural lagoons, and reservoirs in low-wind regions where maximum wind resistance is not required.
Self-Interlocking Hex Tiles
Tiles interlock automatically on the liquid surface without tools or assembly. The interlocking geometry creates a continuous, stable surface layer that maintains coverage even as liquid levels fluctuate.
Low Profile — Fits Enclosed Tanks
The slim tile height allows deployment in tanks with limited freeboard or partial cover structures. Minimizes material volume while maintaining 99% surface coverage performance.
Tool-Free, Rapid Deployment
Pour tiles directly onto the liquid surface — the cover self-assembles immediately. No tools, no heavy equipment, no pond modification required. Operational within hours of delivery.
