# Floating cover

A buoyant surface barrier deployed on the surface of a water body — modular hexagonal, continuous geomembrane, or spherical (armor ball) — to reduce evaporation, algae, odor, and heat loss.

On industrial water sites, a **floating cover** is the procurement category that includes
hexagonal modular covers (the most common choice for reservoirs over 1,000 m²),
spherical floating covers (small or irregular bodies), and continuous geomembrane (full
sealing or gas capture).

In the EuroCover catalog: hexagonal modular →

[Hexofloat®](/products/hexofloat); spherical →
[Armor Ball AQUA](/products/armor-ball-aqua); continuous → not stocked, see the
[geomembrane comparison](/vs/geomembrane).
