EPDM Pond Liners
PondGard Rubber Pond Liner:
The Unique Properties Of EPDM pond liner have a lot of valuable benefits. This product is made by Firestone PondGard. The EPDM liner is a highly stable material, fish and plant friendly. The Firestone PondGard logo imprinted on the EPDM liner indicates that it is specially formulated to be safe for exposure to fish and plant life in decorative ponds. It stays flexible in a variety of temperatures enabling it to be installed year round. PondGard EPDM liner has high expansion and contraction characteristics which enable it to conform to objects in the subgrade. This feature is especially important after the pond is in service when earth movement, or erosion, could cause roots and rocks to be dislodged beneath the membrane, placing stress on the liner.
PondGard's high elongation properties will enable it to stretch over the object. A garden pond liner should conform nicely to bottom contours.You want to have both shallow and deeper areas, and even shelves upon which potted aquatic plants can be set within the pond.
EPDM (ethylene-propylene rubber) is the best liner marterial your money can buy. It is thicker than most pond liners, at 40 to 60 mils. It is also a more rubbery (as in stretchy) plastic, which adds to its life and suefulness. It will stretch around a rock or obstacle in the ground instead of tearing.But there is bad news. As with all things of the highest quality, it is more expensive. You can expect to pay twice as much for an EPDM liner as you would for PVC. The long life of 20-plus years more than makes up for the up-front cost, however; so if you are building a pond that is meant to last, go with EPDM.
You simply cannot build a good pond without a good liner because it is the skin of the pond and one of the most important components of a successful water garden or backyard Koi ponds. The EPDM liner is highly recommended not only from the Koi Pond Guide experts but from many other experts as well.
Here’s a tip: To get the proper measurements for the purpose of buying liner, place one end of a string 18" from the side of the hole and drop it down, across, and up to the other side at the widest part of the hole. Then 18" on the other side. Measure the string. (Remember — once liner is cut there is no returning it and seams will probably eventually leak).

How to calculate what size liner you will need for your water feature:
The basic formaula for determining liner size is:
We recommend a 2" Overlap on all sides of the water feature.
Be sure to measure the longest, widest, and deepest points of your water feature to use in the formula in order to ensure the accurate size. Better to be a little long than to be a little short!
