Longevity is a very important issue in pond liner selection.
Lining a pond is relatively simple when using the several forms of plastic and rubber pond liners which are currently popular. The factors involved when choosing a pond liner will be the dimensions of the pond, the material the liner is made of, and the thickness. Find more about Epalyn pond liners.
Design the pond first and then figure out the size required for the liner. To determine the size of your liner, you will need to measure both the length and width of your pond, as well as double the maximum depth. Also throw in an additional foot or two of overhang all the way around your pond. A liner that is too large is more useful than one which is too little.
Pond liners are constructed from a variety of materials and are available in several different thicknesses, which are usually measured in mils (1 mm = 1/1000 of an inch). If you are constructing smaller ponds, especially when they will be free form, a 0.75mm thickness liner is an excellent choice. If your pond is bigger you may need to consider a more enduring pond liner, constructed from 0.85 to 1.0mm rubber, which should give you many years of reliable use.
There are several diverse materials used to make pond liners. Probably the best material is Epalyn (EPDM), which is an industrial grade rubber and comes in an assortment of sizes. This material is so flexible and resistant to weather conditions so it works perfectly in just about any kind of pond. The only real disadvantage of Epalyn is its higher cost versus PVC liners, but lots of people feel the material is so stress-free to work with and so long-lasting that it is worth the extra money.
A type of plastic which is frequently used for pond liners is PVC (poly vinyl chloride) and is a nice choice for those putting in a new pond with only a modest budget. This is a man-made plastic liner which is moderately sturdy and sold 0.5mm thickness black sheet. It is cheaper than a rubber pond liner and usually flexible enough to shape effectively into tight spaces.
PVC, however has its drawbacks when the purpose involves supporting something as heavy as water. Pond liners made from PVC are usually not as heavy-duty as either Epalyn (EPDM) or Butyl rubber liners, but they usually are cheaper.
Whichever brand of pond liner material you select, make certain that it is UV resistant. This means your liner is shielded from harmful UV rays, which could make it fall apart in only a few years. Pond liner resilience and upkeep depend on the type of material selected, and that can dictate what type of supplies are needed to sustain a healthy pond.
