Description
The liner and its underlay, chosen together
This range pairs a black 200gsm polyethylene pond liner with separate 50gsm fabric underlay. Choose one of sixteen liner cut sizes to suit your measured pond layout. Every option includes both materials: the PE sheet forms the water-holding layer, while the lightweight fabric sits beneath it on prepared ground.
Two materials with different jobs
The PE liner
A flexible polyethylene sheet with a black face and grey reverse. The material is UV-resistant for outdoor pond use. Arrange it around the prepared pond contours without pulling it tight.
The fabric underlay
A separate lightweight 50gsm layer beneath the liner. It does not replace removing sharp objects or choosing any further protection your ground conditions require.
The GSM figures
200gsm refers to the liner; 50gsm refers to the underlay. Both describe material weight per square metre. Neither is a millimetre thickness measurement.
Choose the liner size in both directions
Measure the longest and widest routes through your excavation, following the actual base, sides and shelves. Include enough material to finish and secure the edges. The water surface dimensions alone will not tell you which sheet to order.
Sizes are nominal liner cut dimensions and can vary by ±5%. Allow for that tolerance and check both routes independently. Use the Size menu above for the available options, prices and stock.
Available liner cut sizes
Square liners
2.5m × 2.5m; 3m × 3m; 4m × 4m; 5m × 5m; 6m × 6m; 8m × 8m; 10m × 10m.
Longer, narrower liners
1.5m × 5m; 1.5m × 10m; 2.5m × 3m; 2.5m × 5m; 2.5m × 10m.
Other rectangles
3m × 4m; 4m × 5m; 4m × 6m; 5m × 6m. The selected dimensions describe the liner, rather than a finished pond size.
Build up from prepared ground
Position the fabric first, followed by the liner, keeping the planned allowance at the edges.
Clear and smooth
Remove sharp stones, roots and debris from the base, sides and shelves. Smooth and support the contact surface before laying the materials.
Arrange the fabric
Position the underlay beneath the liner. Check the coverage and any overlaps as you work around corners and changes in level.
Let the liner settle
Unfold the PE sheet and allow it to follow the excavation without stretching it across gaps. Check the liner and the edge allowance before filling.
What is included?
One black and grey 200gsm PE pond liner in the selected cut size, with 50gsm fabric underlay. This is a polyethylene liner bundle, rather than an EPDM rubber liner. Pond edging, stones, plants and other installation accessories are not included.
Choosing your bundle
Is underlay included with every size on this page?
Yes. Each size option on this product page is a PE liner and fabric-underlay bundle. The separate liner-only range does not include underlay.
Does the fabric remove the need to prepare the ground?
No. Sharp objects and rough ground still need attention before installation. The included lightweight fabric is a separate layer beneath the liner, not a guarantee against every puncture.
Can I choose from the pond surface area alone?
No. Check the required liner dimensions through the pond, including depth, shelves and the edge finish. Shape and contour measurements matter as well as the total area.
