A floating cover system composed of independent floating elements (hexagonal, spherical, or other geometries) that tessellate across the water surface.
A modular cover is a floating cover system composed of independent floating elements — most commonly hexagonal or spherical — that tessellate across the water surface. Each element floats independently, allowing the cover to accommodate dynamic water levels, irregular shorelines, and fixed infrastructure (inlets, outlets, pump suctions). Modular covers contrast with continuous (geomembrane) covers, which are single-piece sealed membranes typically requiring anchors and draining for installation.
The market-defining modular cover is AWTT’s patented hexagonal element — the original Hexprotect® (the first self-ballasting hexagonal cover, patented 2010) and the pre-ballasted Hexprotect® AQUA — now deployed across industrial water sites in North America, Latin America, the Middle East, and parts of Africa and Europe. See /heritage for the patent and provenance chain.
