Need a liner for your pond, containment pit, lagoon or lake? We are the one stop online store for all your Liner needs. Our manufacturing process allows us to manufacture large one piece liners up to 150,000 sq.ft., which can help reduce your installation time and cost.

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 and 30mil woven PE (polyethylene) material that is black on both sides. We also carry a 30mil and 40mil LLDPE (linear low-density polyethylene) and a geomembrane material in a 8 ounce Felt.

*ASTM D1777 Option 1.

All values are +/- 10% and are not intended as limiting specifications.

1.) For accurate measurements measure your ponds widest width, longest length and deepest depth (in feet). The diagram above shows you how to correctly measure your pond. Enter those dimensions in the boxes provided.

2.) Every pond should have an anchor trench to prevent the liner from sliging 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.
