Is a boxwelded or preformed pond liner suitable for me?
High-quality solutions for formal-shaped ponds
Box welds are prefabricated pond liners made to fit a pond’s exact dimensions. As they are created for specific shapes, preformed liners are best suited to square and rectangular ponds, but can also be used in circular designs. A popular choice for formal, ornamental, and koi ponds with vertical sides, these types of pond liners have welded seams that allow for easier cleaning, maintenance, and installation.
Unlike flat sheet liners, box welded pond liners are smooth and crease-free. This means that they are not only more visually appealing but they can also prevent waste and debris from entering a pond and affecting its water quality.
At Catalogue Engineering, we offer:
Pre-fabricated box welded pond liners, top hats, tapes, and textiles for every specification
Fully welded oversized panels for larger ponds
Preformed liners welded in a controlled environment
A full range of membrane options (LLDPE, HDPE, PP and more)
Geo-membranes from 0.4mm-2.0mm
Dispersal units in various sizes.
