How we work out the size
We add twice the deepest point to the pond’s length and to its width, so the sheet runs down the sides and across the floor, then add 30 cm on every edge to tuck under the edging. We pick the smallest sheet we stock that covers that, either way round.

The underlay, in the same
size as your liner
Liner and underlay cover the same hole, so they are bought in the same sheet size. The underlay below follows the size you chose above.

Laying it, in four steps
- 1
Shape the hole
Dig the pond with its shelves, then pick out sharp stones and cut back any roots you can see.
- 2
Lay the fleece
Spread the underlay across the hole and press it into the base, the shelves and the corners. Let it run up over the edge.
- 3
Liner on top
Lay the liner over the fleece and start to fill. The weight of the water pulls both layers into shape.
- 4
Trim when it is full
Once the pond is full, trim the liner and the underlay together, leaving enough to tuck under the edging.

Questions before you buy
Do I need underlay under the liner?
We would always fit it. Stones work their way up through soil over the years and roots keep growing, and once the pond is full the underside of the liner is the one place you cannot get back to.
My pond is bigger than the largest sheet, or an awkward shape
Our largest sheet here is 50m x 40m. For a bigger pond or an awkward shape, send us the measurements with the Quote button above and we will work out the sheets you need.
