Pond Lining Drainage Information | Stephen Industries
In certain situations water or gas can become trapped under the liner, for example; if the pond is built on clay, the soil contains organic matter that could generate methane gas, or if there is a high / fluctuating water table. Over a period of time, any of these conditions may cause damage to the pond liner, but they can be prevented by installing a drainage system of porous pipes laid in a sand bed or other permeable layer.
