The definition
A box welded pond liner is a or rubber pond liner that has been cut and hot-air welded at the corners and edges to produce a three-dimensional shape — a box — that exactly matches the interior of your pond. Unlike a flat sheet liner, there is no excess material to fold away. The liner simply drops in.
Why the shape matters
With a flat sheet liner, the surplus material at the corners must go somewhere. It gets folded, pleated or tucked — and over time those folds trap sediment, harbour algae and create stress points in the liner material. A box welded liner eliminates this entirely. Every surface lies flat. The base is clean. The walls are taut.
How it's made
We cut the pond liner material to a precise pattern and weld each corner and edge using hot-air welding equipment. Before any material is cut, we produce a scale drawing of your liner and send it to you for approval. Nothing is manufactured until you have signed off the drawing.
