  • Build your garden pond: a 2.5m × 2.5m 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 square sheet for a well-planned pond

This 2.5m × 2.5m black and grey pond liner provides a nominal 6.25m² of flat polyethylene. The flexible 200gsm PE material follows the prepared shape of your garden pond, while the square format gives the same starting dimension in both directions.

Leave room for more than water

A 2.5m square liner does not make a pond with a 2.5m square water surface. The sheet also has to reach down the sides, across the base and over the edges. Shelves and changes in depth use material too.

Measure along the longest and widest routes through the excavation, following its actual contours. Include the allowance for your chosen edge finish and the ±5% cut-size tolerance. Check both dimensions before ordering, rather than relying on the flat area alone.

One PE liner, with underlay chosen separately

Your order contains one nominal 2.5m × 2.5m sheet, with a black face and grey reverse. The PE material is UV-resistant for outdoor pond use. The 200gsm figure means grams per square metre; it does not state a thickness in millimetres.

Use suitable underlay beneath the liner. It is required and sold separately, along with edging, stones, plants and other installation accessories.

Build from a smooth base

Ground preparation comes before the underlay and liner, even for a smaller pond.

Illustrative preparation, not a size guide. Underlay and installation accessories are sold separately.

Clear the excavation

Remove sharp stones, roots and debris. Smooth the base, sides and any planting shelves so the liner is supported.

Position the underlay

Choose protection suited to the ground and arrange it beneath the liner. Check that the layers stay in position around corners.

Follow the contours

Unfold the liner without stretching it tight across the pond shape. Retain the planned material at the edges and check before filling.

Choosing this sheet

Is 6.25m² the finished pond area?

No. It is the nominal area of the liner laid flat. Depth, sides, shelves and edging use part of the sheet, leaving a smaller finished water surface.

Does the liner come with underlay?

No. This product supplies one PE liner only. Choose suitable underlay separately for the ground conditions and coverage beneath your liner.
