To prevent wrinkles in the pond liner during installation, start by ensuring the pond base is smooth and free of sharp objects, which can create bumps and indentations. When placing the liner, unfold it carefully from the center outwards, allowing it to gradually settle into the contours of the pond without forcing it into tight areas.
To accommodate curves and sharp corners, the liner can be carefully pleated to avoid unsightly wrinkles that could weaken the liner over time. Once the liner is laid out, fill the pond slowly with water to help the liner conform to the excavation's shape, as the weight of the water pushes the liner into the correct position. It's best to monitor the liner as it settles and pause to make corrections as you go to avoid creating excessive tension in any area. If you notice any wrinkles forming, you may be able to gently adjust the liner while as it continues filling.
