Shelton, CT (PressExposure) January 05, 2012 -- A Pond liner is an impermeable geomembrane used for water retention, including the lining of lakes, garden ponds and artificial streams in parks and gardens. EPDM liners need to be protected from sharp objects (eg stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, concrete, fiber-matting and other materials. Pond liners are manufactured in rolls. Strips of liner can be seamed or welded together on site; and a number of flexible types, such as EPDM, can have their panels pre-fabricated together in the factory to fit the design shape of the pond.
The edge of the pond liner can be rolled over and secured in a trench or it can be fixed to a vertical wall made in brick or concrete. Box-shaped pond liners can be made for rectangular structures. The vast majority of flexible pond liners available commercially are manufactured of EPDM, butyl rubber with EPDM being the most popular at the moment due to cost. A newer method involves a spray-based coating known as polyurea, and though the cost of using polyurea is considerably higher than flexible sheets, the lifespan of the material may be much longer than any other.
It's a good idea to lay your liner out on a clean surface in the sun for thirty minutes or so to make it more pliable. If the weather is too cool, a hair dryer is very handy to gently warm the materials. Warning, don't do this over your lawn, as the heat will kill your grass. With some gift wrapping expertise, creases and folds can be handily disguised in corners. Drape the excess liner over the edge of the frame: but don't cut it! As with in-ground liner basins, newspaper or carpet may be used for protection against puncture by placing between the membrane liner and the structural form.
