About this range
Underlay goes between the ground and your pond liner. Our 50gsm non-woven black fabric underlay is available in 3m x 3m, 3m x 5m and 3m x 10m sheets.
The product details describe it as protecting the liner from sharp stones, roots and ground abrasion. Lay it across the excavated pond before fitting the liner.
