# Continuous (geomembrane) cover

A single-piece sealed floating cover, typically geomembrane, with 100% surface coverage. Used where complete gas capture or environmental containment is required.

A **continuous cover** (or geomembrane cover) is a single-piece sealed floating membrane that
provides 100% surface coverage. Continuous covers are typically anchored to the reservoir shoreline
and require draining for installation. They are the appropriate choice for applications requiring
full gas capture (methane recovery on biogas digesters) or environmental containment. For surface
management (evaporation, algae, odor) on dynamic water bodies, modular covers are usually more
cost-effective. The market-leading modular alternative is the AWTT-patented self-ballasting
hexagonal cover — see [/heritage](/heritage) for the engineering rationale.
