Pond liners are the foundation of garden ponds, koi ponds, waterfalls, or water gardens. Pond liners eleminate the water from soaking into the ground which results in refilling your pond almost on a daily basis. Pond liners also keeps your pond pump and pond filters from clogging with mud. With no mud in the bottom of your pond means a clearer pond.

Flexible pond liners allow for an easy and a very forgiving installation. EPDM pond liners are highly recommended for most residential ponds because they are the most flexible type of liner. All our pond liners are fish safe and long-lasting. Browse our complete supply of pond liners. Other choices include concrete and preformed ponds. Concrete installations usually require a professional installation as well as being a medium that tends to crack as the ground freezes and thaws. Preformed ponds are good for some indoor installations, but are difficult to install outdoors as the hole must match the shape to avoid shifting and cracking.

A pond liner underlay is recommended for all pond liners, especially EPDM liners. Pond liner underlays make all pond liners more puncture resistant by protecting pond liners from sharp objects in the soil such as rocks and roots. Pond liner underlays resist settling, unlike newspaper or sand, which stablizes the ground under the pond liner to keep EPDM and other pond liners from over-stretching.

If your not sure about what size pond liner you might need visit our Pond Liner Calculator to figure the size pond liner you need. Remember, adding an extra 1 foot in all dimensions will allow for rocks to weight down the pond liner while filling your pond with water.
