PVC pond liner
PVC is a lightweight, water tight 0.5mm thick black sheet used for lining ponds. PVC is best used for smaller installations such as ornamental garden ponds as it is very flexible and moulds well around corners and shelves. It is not very elastic however, and needs to be fitted carefully as it will not stretch into small gaps and crevices. PVC pond liner is not easily repaired as it has a tendency of going brittle when most pond liner repair products are used on it. It will crack in these areas over time and leak again. PVC is UV resistant but will go brittle and crack if exposed to the sun over a period of time therefore correct installation and maintenance are essential. A very economical pond liner.
