Size Guide
To calculate the liner size you need:
- Liner length = pond length + (2 × max depth) + 0.5m
- Liner width = pond width + (2 × max depth) + 0.5m
For example, a 1m × 1m pond with 0.5m depth needs approximately a 2.5m × 2.5m liner — so the 2m × 2m is ideal for very shallow ponds or the 2m × 3m if you need a little more depth or width flexibility.
Installation Tips for Small Ponds
- Dig your pond shape and remove all sharp stones and roots
- Add a layer of sand (25–50mm) to protect the liner base
- Lay the liner loosely, working from centre to edges
- Fill slowly with water — the weight helps the liner settle
- Trim excess, leaving 150–200mm overlap around the rim
- Secure under turf, decking, paving slabs or decorative stones
