How to calculate your liner dimensions?
To determine the ideal size:
Liner length
= Maximum pond length + (2 × maximum depth) + 1 meter margin (50 cm on each side).
Liner width
= Maximum pond width + (2 × maximum depth) + 1 meter margin (50 cm on each side).
This margin ensures proper anchoring of the membrane around the entire perimeter of the pond.

For maximum protection
An EPDM membrane is designed to last for several decades. To preserve all its qualities over time, we recommend installing a Premium Aquitechnics 400 g/m² geotextile felt under the liner.
This effectively protects the membrane against:
✔ stones
✔ roots
✔ ground irregularities
✔ pressure points
✔ risks of puncture
👉 For a complete installation, also discover our Aquitechnics EPDM Liner + Premium Felt Pack, specially designed to ensure optimal protection from the moment of installation.
