  • Build your garden pond: a 8m × 8m nominal sheet of flexible 200gsm PE for the water-holding layer.
  • Follows your pond's contours: flexible polyethylene fits around curves, shelves and changes in depth without a rigid preformed shape.
  • Black face with grey reverse: UV-resistant PE for outdoor ponds and garden water features.
  • Choose your own underlay: suitable protection is required beneath the liner and is sold separately.
  • One liner supplied: cut-size tolerance ±5%. Allow for depth and edging; prepare smooth ground and remove sharp debris before fitting.

Description

A broad PE sheet for your planned pond shape

This nominal 8m × 8m pond liner provides 64m² of flat polyethylene material. The flexible sheet follows a prepared excavation, with material distributed over the base, side walls, shelves and edges.

The 200gsm liner has a black face and grey reverse, with UV resistance for outdoor pond use. Fit it over suitable underlay, chosen for the actual ground conditions.

One liner supplied. Underlay sold separately.

Plan by the complete measurements, not area alone

The nominal 64m² area is all the flat liner material supplied. Depth, side walls, planting shelves and the perimeter finish use part of that same sheet, so it is not a 64m² water-surface allowance.

Measure the longest and widest routes along the actual excavation contours and add the material required for your edge finish. Compare both complete measurements with the nominal 8m sides, allowing for the ±5% cut-size tolerance. A square sheet can follow a curved or irregular pond if those routes fit.

Prepare the full supporting area

Underlay is required beneath this liner and is not included. Plan sufficient protective coverage and overlaps, using protection appropriate to your actual ground conditions. The fabric options shown above are sold separately.

Clear the excavation

Remove sharp stones, roots and debris from the base, sides and shelves. Smooth the surfaces that will support the underlay.

Lay out the protection

Arrange coverage around the contours and plan any overlaps. Do not assume one fabric sheet will cover the entire excavation.

Ease the liner into shape

Let the PE settle into the contours without stretching it tight across gaps. Leave the perimeter allowance and check the position before filling.

What is included?

One nominal 8m × 8m 200gsm polyethylene pond liner with a black face and grey reverse. Underlay, plants, stones, edging and installation accessories are not included.

The 200gsm figure describes material weight per square metre, not thickness. This liner is PE rather than EPDM rubber. Multiple quantities supply separate liners, not one larger sheet.

Questions about the 8m × 8m liner

Does the liner come with underlay?

No. This product supplies the liner only. Underlay is required and sold separately. Plan coverage, overlaps and protection for the actual excavation and ground conditions.

Will it cover an 8m × 8m pond opening?

Do not choose it from the opening dimensions alone. Depth, sides, shelves and the perimeter finish require material in both directions. Measure the full contour routes and allow for the ±5% cut-size tolerance.

Is 200gsm a thickness measurement?

No. It is the liner's material weight per square metre. It does not describe thickness, and the polyethylene sheet is a different material from EPDM rubber.
