Half Off Ponds 20-Mil LLDPE Pond Liner
20-Mil LLDPE is an economical, extremely durable pond liner with high tear and puncture resistance, and high impact and tensile strength, yet is pliable and flexible, conforming to a variety of irregular surfaces.
Half Off Ponds LLDPE is an excellent choice for residential project like water gardens, fish ponds and backyard waterfalls with gently sloping sides and smooth contours. Half Off Ponds LLDPE also meets the demands of landscape contractors and water feature installers working large commercial and municipal projects like business campus retention ponds, public works water features and residential beautification installations.
Half Off Ponds LLDPE attaches easily to waterfalls and skimmers. It works best in sweeping corners and bottom transitions. LLDPE does not easily conform to tight corner radiuses or sharp bottom-to-side angles.
Half Off Ponds LLDPE is completely fish, wildlife and aquatic plant safe. It resists stress cracking and is backed by a 10-Year Manufacturer's Warranty, even if it's exposed to direct UV radiation. In non-exposed installations, where the liner is covered by earth, rock or water and shielded from direct UV radiation, Half Off Ponds LLDPE has a life expectancy of 40 years or longer; and that’s a very long time!

Frequently Asked Questions
1. What is LLDPE?
Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins. Linear low-density polyethylene differs structurally from conventional low-density polyethylene (LDPE) because of the absence of long chain branching.
The linearity of LLDPE results from the different manufacturing processes of LLDPE and LDPE. In general, LLDPE is produced at lower temperatures and pressures by copolymerization of ethylene and such higher alpha-olefins as butene, hexene, or octene. The copolymerization process produces an LLDPE polymer that has a narrower molecular weight distribution than conventional LDPE and in combination with the linear structure, significantly different rheological properties.
2. What size liner do I need?
The formula for sizing a pond liner is:
(Pond Length') + (2 x Pond Depth') + (2') =
Liner Length'
(Pond Width') + (2 x Pond Depth') + (2') =
Liner Width'
So... if you want a finished pond that is 12' long, 7' wide, and 3' deep; then using the formula above, the liner size you need is:
(12') + (2 x 3') + (2') =
20' Long
(7') + (2 x 3') + (2') =
15' Wide
This basic formula will work for ALL pond shapes.
3. How many gallons of water is in my pond?
The formula for determining the number of gallons of water in a pond is simple.
(Pond Length') + (2 x Pond Depth') + (2') =
Liner Length'
For Square and Rectangular Ponds:
(Pond Length') x (Pond Width') x (Pond Depth') x 7.5 =
Gallon Size
For example, if you want a finished pond that is
rectangular
in shape, and is 12' long, 7' wide, and 3' deep; then using the formula above, the gallon size of your pond is:
(12') x (7') x (3') x 7.485 =
1,890 Gallons
For Oval Ponds:
(Radius1') x (Radius2') x Pi(3.14) x (Average Depth') x (7.485) =
Gallon Size
For example, if you want a finished pond that is
oval
in shape, and is 12' at the widest length accross, 7' at the shortist length accross, with a 3' average depth; then using the formula above, the gallon size of your pond is:
(6') x (3.5') x (3.14) x (3') x 7.485 =
1,480 Gallons
4. How deep should I make my water feature?
For fish ponds, a depth of at least 18", or deeper is recommended. Healthy fish
LOVE
to move up and down, as well as side to side!
For water gardens, the water feature should have a depth of at least 12", or deeper.
Check your local fence requirements (building codes) and freeze line depth.
