Hexprotect® AQUA — pre-ballasted hexagonal floating cover
AWTT's pre-ballasted, one-piece moulded hexagonal floating cover — the workhorse of the AWTT line since 2009.
Hexprotect® AQUA is AWTT’s pre-ballasted, one-piece moulded hexagonal floating cover — the workhorse of the AWTT product family since 2009, certified to 130+ MPH wind and a 25+ year service life.
What is Hexprotect® AQUA?
Hexprotect® AQUA is the pre-ballasted variant of AWTT’s patented hexagonal floating cover. Each tile is a one-piece moulded HDPE hexagon with a raised central dome, pre-filled at the factory with potable water as fully-contained ballast. Tiles deploy anchorlessly onto an operating water body and self-tessellate at 99% effective surface coverage.
How it works
- Element geometry. Each tile is a hexagon with a raised central dome. The dome sheds rainfall toward the seams between adjacent tiles (back into the water body), prevents pooling, and dissipates wind energy.
- Pre-filled ballast. Replacing the open self-ballasting chamber of the original Hexprotect® with a one-piece moulded shell pre-filled with potable water. The ballast is fully contained inside the shell, so it cannot be lost when the float tips.
- Smooth outer surface. No recessed areas means debris and dirt shed naturally — critical for keeping the cover clean and effective in the field.
- Tessellation. Hexagonal footprint packs at 99% effective surface coverage (AWTT-published) when fully laid out — higher than any other modular cover geometry.
- Wind dissipation. The pre-ballasted, one-piece design dissipates wind energy through controlled lateral motion of individual tiles. No anchors required.

When to use Hexprotect® AQUA
- Industrial reservoirs and process water tanks over 1,000 m².
- Mining tailings ponds, agricultural irrigation storage, biogas digestate.
- Sites where 25+ year design life and hurricane wind rating are the dominant criteria.
- Potable-water service reservoirs (specify the NSF/ANSI food-grade variant).
- Irregular shorelines or fluctuating water levels (the modular tessellation tolerates both).
Hexprotect® AQUA vs Hexofloat®
Hexofloat® is the EuroCover-tooled, AWTT design-approved alternative — a lighter 190 mm tile with a 75 MPH wind rating and a 15-year service life, targeted at projects where EU manufacturing origin or a 3–6 week lead time is the binding procurement constraint. For deployments where wind exposure or design-life dominate, AQUA stays the pick. See the full AQUA vs Hexofloat® comparison.
