This pond liner is the most popular model in our range. The liner is 2.5m in width and 2.5m in length (8\'2\" x 8\'2\"). The suggested pond size for this liner is 90cm x 90cm x 30cm deep (3\' x 3\' x 1\' deep). The pond liner material is LDPE (low density polyethylene). During the manufacturing process a core of tightly woven LDPE thread is sandwiched between two tough laminated coats. The result is a pond liner which is tearproof but still malleable and easy to fit into position.
