Pond liners for recreational and landscaping use are designed out of various materials and in various styles and strengths to accommodate all needs. These liners are used in a number of applications including canals, lakes, aquaculture ponds, secondary containment areas and in golf course ponds. There are often a variety of terms associated with pond liners including liner underlay and fish safe liner. There are also many types of materials available too, such as geo-pad and polyethylene pond liners.

Geo-pad

A geo-pad is a type of pond liner made from polypropylene nonwoven fabric that is needle punched. It is an ideal choice for many ponds, because it does not degrade from ultraviolet exposure and it is not biodegradable.

Liner underlay

Liner underlay is sized to fit directly under the pond liners. It is an extra layer of protection heavily recommended by many pond manufacturers and liner manufacturers. It aids in preventing tears or punctures in the liner from ruining the pond. It also protects liners from anything added to the pond and anything lying under it in the soil.

EPDM pond liners

One of the most common types of pond liners are the EPDM pond liners. They are able to expand and contract without problem. They move easily, for example, when there is settling, to protect the pond from damage. They are easily shaped to fit any size pond hole and contours.

A fish safe liner means that the liner can be used in ponds housing fish and other wildlife. Not all liners will state that they are fish safe. Therefore, it is important to know if the product is suitable for fish prior to allowing them into this habitat.
