EPDM Pond Liners have high expansion and contraction characteristics that enable it to conform to objects below the pond. Should earth movement occur, such as settling, EPDMs high elongation will enable it to stretch.
EPDM pond liners flexibility provides more versatility in the pond design. Unlike preformed liners, it can be easily shaped to fit the unique contours of the pond dimensions, allowing a more unique design.
EPDM Pond Liners stay flexible in temperatures from -40 Fahrenheit to 175 Fahrenheit making it easy to install year round. Unlike other liner materials, EPDM Pond Liners do not contain plasticizers that could make it become brittle with age and cause cracks or splits in the material, threatening aquatic life.
EPDM Pond Liners requires little or no regular maintenance once installed. Remarkable resistance to the harmful effects of ultraviolet radiation (UV), ozone and other environmental conditions.
45 mil EPDM liners have quickly become the industry standard; they are affordable, flexible enough to allow better fit, fairly resistant to UV, and often carry a 20 year manufacturers warranty. Other liner materials, including butyl rubber and PVC may be less expensive, but are often harder to install and less durable. Also popular are small preformed plastic ponds which are quite durable, but not as easy to install as they would appear.
"Mil" simply refers to the thickness of the material, so the 45 mil would be thicker and therefore stronger (assuming the same material). 45 mil liners are also usually made of EPDM and carry a 20 year warranties, while 32 mil are made of lesser materials with shorter warraties.
An underliner protects the pond liner from puncture by sharp objects such as stones and roots. Failure to protect the pond liner from punctures may void its warranty. We offer an inexpensive commercial underliner; otherwise, a layer of sand, newspapers, old carpet or insulation could be applied.
Pre-formed ponds cannot be used free-standing. They need to be dug in and back-filled. The entire pond bottom and all plant shelves need to be well supported to eliminate the possibility of cracking.
Trees produce roots that might pierce the pond liner, and leaves and other debris that might fall into the pond. They also shade the pond, which may limit plant growth. Ponds may also inhibit tree growth by restricting root development. Ponds in low lying areas can be contaminated by runoff such as lawn fertilizers and weed killers, and possibly overflow.
