12.1.2 Pond construction

There are three basic methods of pond construction: concrete, moulded glass fibre, and plastic or polythene flexible liners. The construction of a garden pond from concrete is hard work and although the finished article is permanent, it may crack as a result of frost and ice. Moulded pools are very easy to install but can be expensive and some are too shallow to maintain fish through the coldest winter months.

Flexible liners are a popular choice; several types exist ranging from little more than a thin sheet of plastic or polythene, to very tough butyl liners, which are almost as permanent as a concrete of moulded pool. Full details on pond construction can be found in the popular literature.
