  • Underlay included: 1 separate 3m × 10m sheet of 50gsm fabric for laying beneath the liner.
  • One liner supplied: cut-size tolerance ±5%. Allow for depth and edging; prepare smooth ground and remove sharp debris before fitting.

Description

A long PE liner with underlay included

One nominal 2.5m × 10m black and grey pond liner, supplied with 50gsm fabric underlay. The flexible 200gsm polyethylene sheet provides a nominal 25m² of flat liner material in a long rectangular format.

Plan the liner and protective layer together.

Choose this size from the full measurements through your pond, including its depth and edge finish. The sheet dimensions are not the water surface dimensions.

Check the shorter route before using the longer one

The sheet is four times as long as it is wide. Its 2.5m side still needs to reach through the excavation, with enough material for the sides, depth and perimeter. Extra length cannot provide extra width.

Measure the longest and widest routes along the actual contours, including shelves and changes in level. Add the allowance for your edge finish and compare both with the 2.5m × 10m liner, accounting for the ±5% cut-size tolerance. A 25m² flat area does not confirm the fit on its own.

Give both layers a prepared base

The PE liner is flexible and UV-resistant for outdoor pond use. The included fabric goes underneath it, with its coverage arranged for the actual excavation.

Clear sharp objects

Remove stones, roots and debris from the base, sides and shelves. Smooth the supporting surfaces before fitting the layers.

Plan the fabric layout

Check coverage and any overlaps along the whole pond. Assess whether the ground conditions need further protection before positioning the liner.

Let the PE settle

Ease the sheet into contours without stretching it tightly across gaps. Keep enough at the edges and check its position before filling.

What arrives in the bundle?

One nominal 2.5m × 10m 200gsm polyethylene pond liner and 50gsm fabric underlay. The liner has a black face and grey reverse; the fabric is the distinct protective layer beneath it.

The two GSM figures describe the separate materials' weight per square metre. They are not a combined liner weight or a thickness measurement. This is PE rather than EPDM rubber. Edging, plants, stones and installation accessories are not included.

Before choosing this long format

Does this bundle include the underlay?

Yes. It includes 50gsm fabric underlay as well as one nominal 2.5m × 10m PE liner. Plan the fabric coverage and any overlaps for your excavation.

Will it cover any pond with less than 25m² of water?

No. Depth, shape and edging affect the material required. Measure both full routes through the pond rather than choosing from water surface area alone.

Can the included fabric replace clearing the ground?

No. Remove sharp objects first. The 50gsm fabric is a lightweight layer, so assess any further protection needed for your actual ground conditions.
