Box welded pond liner is tailored to fit vertically sided earth, brick or concrete formal shaped ponds (rectangles, circles or “L“ shapes). Formal ponds with planting shelves, sloping bases, uneven depths or a haunched base to fit a bottom drain to Koi ponds, can all be accommodated.
The advantage to installing a box welded pond liner versus a flat sheet liner is that they eliminate folds and unsightly creases. Ponds where there are folds to the pond liner have the potential for harbouring debris. This can then lead to the growth of unwanted pathogens and as a result, adversely affect the quality of water threatening the health of fish.
