# Modular vs. continuous floating covers — comparison

> Modular hexagonal floating covers are independently floating tessellated elements that deploy without anchors; continuous floating covers are single-piece sealed membranes (often anchored) suited to full gas capture and environmental containment.

For an EU industrial site, EuroCover usually quotes modular when the brief is surface
management — evaporation, algae, odor, heat retention — and continuous geomembrane only
when full sealing or gas capture is in scope. Hybrid deployments (continuous on the digester
core + modular on adjacent digestate storage) are common at biogas plants. The engineering
side of this choice lives at

## The modular case

- Anchorless deployment
- Deploy on active reservoir without draining
- Tolerant of dynamic water levels and irregular shorelines
- 25+ year lifecycle
- Per-element replacement maintains long-term coverage

## The continuous case

- Full sealing (100% coverage)
- Methane / biogas capture
- Environmental containment
- Regular reservoir geometry assumed
