Liner material thickness is measured in mils or 1000ths of an inch. Inland Tarp & Liner carries a wide range of liner materials to fit almost any application. Our standard liner materials are a 12mil, 16mil, 20mil, 24mil, 30 Mil LT and 30mil Coated Woven Polyethylene material that is black on both sides. We also carry a 30mil and 40mil LLDPE (linear low-density polyethylene) in both smooth and textured surfaces and a geomembrane material in a 8 ounce Felt.

Our material is made from a black woven polyehtylene material. This product generally has a low density coating of 1.5 to 2.5 mil thick on either side of a high density woven scrim. The woven scrim provides great tensile and tear strength properties while the coating gives this product the ability to container liquid. Polyethylene in general has great chemical resistance properties which makes this product a good choice for specific short term applications. Always check to ensure the product you are containing is compatible with the liner material you have chosen. With a properly prepared sub grade in conjunction with recommended non-woven geotextile protective cushions above and below the liner, a coated woven polyethylene liner can be backfilled and remain in use for several years. Coated woven polyethylene is commonly used for short term exposure applications such as pit liners, pond liners or soil remediation.

1.) For accurate measurements measure your ponds widest width, longest length and deepest depth (in feet). Enter those dimensions in the boxes provided.

2.) Every pond should have an anchor trench to prevent the liner from sliding down the slope and into the pond. We recommend no less than a 12" wide and 12" deep anchor trench. The deeper the pond the larger the anchor trench.

3.) All liners have some degree of expansion and contraction as the ambient temperature changes from summer to winter and back to summer. Therefore, liners must be installed with some slack ripples. A liner that is installed tight without these slack ripples can trampoline in the base and corners- in turn creating a liner failure. A liner installed in a colder climate or at a cooler time of day will require more slack ripples. We recommend adding 1' to 3' to each side of your final measurement to accomodate for this requirement.
