Box welded liners for water features
Rills, cascades, reflection pools and formal features — all manufactured to your exact dimensions. Clean lines guaranteed.
Why choose a box welded liner for your water feature?
Clean lines where it counts
Formal water features are architectural — every visible surface matters. A box-welded liner delivers straight walls and flat bases with no visible folds.
Complex shapes handled
L-shaped rills, step-down cascades, raised reflection pools — if you can draw it, we can manufacture it.
Drawing-based process
For complex features, the drawing approval stage is essential. We produce a detailed scale drawing you sign off before anything is made.
Formal water features demand visible precision
A rill, reflection pool or cascade is an architectural element — every surface is in view, and the quality of the finish is part of the design. A flat sheet liner in a formal water feature is unacceptable: the folds at the corners are clearly visible, the walls bow inward where the material bunches, and any imprecision in the fit is immediately apparent in the reflective water surface above it. Box welding produces liner panels with flat walls, clean welded corners, and no surplus material. When the feature fills, the liner disappears and the water takes over.
Rills, cascades and multi-level features
Water features often involve complex geometry — a rill may have multiple runs at different heights connected by weir drops; a cascade may have a series of step-down pools; a formal feature may incorporate a raised header pool feeding a lower reflection pool. We manufacture each section of the liner geometry as a single welded piece where possible, minimising the number of separate panels and therefore the number of joints. Where a single-piece liner is not practical — for example, a very long rill — we manufacture in sections with overlapping joints specified for the flow direction.
Working from drawings
For all water features — and especially complex ones — we work from a scale drawing that you approve before manufacture begins. This drawing shows every panel, weld line, inlet and outlet position, and overhang allowance. It is also your confirmation that the dimensions are correct before any material is cut. If you have CAD drawings of the feature, send them over; if not, a dimensioned sketch is sufficient for us to produce a manufacturing drawing. See our measuring guide for how to document your feature dimensions clearly.
Shapes we manufacture
What to measure
For a water feature liner, we need:
- Overall length (m)
- Width (m)
- Depth (m)
- Location and size of any inlets or outlets
- Overhang allowance for the coping detail
Frequently asked questions
Yes — a rill is simply a long, narrow rectangle. Provide the internal length, width and depth and we will manufacture accordingly. For very long rills, we may recommend a welded-in-situ approach.
Yes. If your design includes a weir or overflow, we can accommodate this in the liner design — note it on your enquiry and we will factor it into the drawing.
There is no minimum size. We manufacture liners for features from small courtyard ponds to large commercial installations.
