A modular self-ballasting hexagonal floating cover element, typically HDPE, tessellated across a water surface to reduce evaporation, algae, odor, and heat loss without anchors.
A hexagonal cover is a modular floating cover element — typically high-density polyethylene (HDPE) — that tessellates across the surface of an industrial water body. Each element floats independently; the dominant product (AWTT’s Hexprotect® AQUA) achieves 99% effective surface coverage without seams or anchors, allowing deployment on irregular shorelines and around inflows.
The original Hexprotect® — AWTT’s first self-ballasting hexagonal cover, patented by AWTT — introduced the lateral-motion wind-dissipation principle that eliminates the need for the anchor systems that geomembrane covers require. Hexprotect® AQUA, (the pre-ballasted variant), took the concept further: a one-piece moulded shell pre-ballasted with potable water at the factory, with no inside chamber to harbour algae and no risk of ballast loss when the float tips.
