Description
A long, narrow sheet for a carefully measured pond
This 1.5m × 5m pond liner provides a nominal 7.5m² of black and grey polyethylene. Its narrow rectangular shape is useful when your measured liner layout calls for a longer sheet without the width of a larger square. Check both routes through the excavation before choosing it: depth and edging use material across the width as well as along the length.
Check the narrow dimension first
The 1.5m measurement is the width of the flat sheet, not the finished pond. Material used to reach down each side, follow the base and finish the edges all comes out of that width. A generous length cannot make up for a sheet that is too narrow.
Measure along the actual contours in both directions, including any shelves and changes in level. Add the allowance needed for your edge finish and leave room for the ±5% cut-size tolerance. If either measured route is too large, choose a different sheet size before installation.
Black and grey polyethylene, supplied as one liner
The 200gsm PE sheet has a black face and a grey reverse, with flexibility for following the prepared pond contours. The material is UV-resistant for outdoor pond use. GSM means grams per square metre; it is not a thickness measurement or a promise of puncture-proof performance.
One nominal 1.5m × 5m liner is supplied. Underlay is required and sold separately. Edging, plants, stones and other installation materials are not included. Multiple quantities are separate sheets; joining materials are not supplied.
Give the liner a prepared surface to follow
Remove sharp debris and lay suitable underlay before positioning the PE sheet.

Prepare the excavation
Clear sharp stones, roots and debris from the base and sides. Smooth and support the ground, including corners and shelves.
Protect from beneath
Choose underlay for the ground conditions and arrange it beneath the liner. Check its coverage as you position the layers.
Position without tension
Let the flexible sheet follow the contours without stretching it across gaps. Keep the planned allowance at the edges and check the liner before filling.
Planning this narrow liner
Can the finished pond be 1.5m wide?
Not if the liner also needs to go down the sides and finish over the edges. Those parts use some of the 1.5m sheet width. Measure the full cross-section through the pond rather than just its water surface.
Is this supplied with underlay?
No. This product supplies one PE liner only. Suitable underlay is required and sold separately; choose its quantity and layout for the prepared ground beneath your liner.
Will ordering two give me one larger liner?
No. Each quantity is a separate nominal 1.5m × 5m sheet. No joining materials are included. Choose a single sheet size that suits your planned installation where that is what your project requires.
