Pond liners are useful for ensuring their watertightness. Their use allows for the creation of ornamental ponds in various shapes to accommodate fish and aquatic plants. Whether in PVC, composite materials, or EPDM, these liners are available in various thicknesses.
Some information to know about PVC pond liners includes:
- they are available in 3 thicknesses ranging from 0.5 mm to 1 mm;
- they are appreciated for their affordable price;
- their installation requires special know-how due to the folds that can form;
- their lifespan varies from 5 to 15 years depending on their thickness.
Pond liners made of composite materials also have some characteristics to note:
- they are made from polypropylene and polyolefin copolymers;
- they are valued for their strength and lightness;
- they are easy to install due to their flexibility;
- they withstand both heat and cold, as well as puncture and tension;
- they are recyclable and have a lifespan of 25 years.
EPDM liners are a popular alternative among professionals for their numerous advantages:
- they are easy to install thanks to their elasticity;
- they can be glued onto a wooden, concrete, or metal surface;
- they withstand temperature variations (from -30°C to 90°C);
- they have a lifespan of 50 years.
The following parameters should be considered to perfectly cover the pond:
- to obtain the length of the liner to purchase, add to the length of the pond twice its depth and 1 m for the edges (50 cm on each side);
- the same calculation method applies for the width of the liner by replacing the length of the pond with its width.
Ultimately, the choice of pond liner depends on each individual's budget, as prices vary depending on the selected manufacturing material and thickness.
