# Modular cover

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](/heritage)
