Half Off Ponds 20-Mil LLDPE Pond Liner
20-Mil LLDPE Liner 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 and attaches easily to waterfalls and skimmers.
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. It resists stress cracking even if it's exposed to direct sunlight. In non-exposed installations, where the liner is covered by earth, rock or water and shielded from direct sunlight, Half Off Ponds LLDPE has a life expectancy of 40 years or longer; and that’s a very long time!
Features and Tech Specs:
Note: LLDPE does not easily conform to a tight corner radius or sharp bottom-to-side angles.
10-Year life expectancy when exposed to direct sunlight amp; 40+ years of life expectancy when not exposed to direct sunlight and when covered by earth, rock or water.
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 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.
We highly recommend using an underlayment when installing any type of pond liner. We offer an underlayment that adds an extra layer of protection between pond liner and rocky or unstable soils while preventing air voids between the liner and earth reducing wear and abrasion. The biggest contributors to project failures is poor, unstable soil conditions.
UnderGuard Underlayment is perfect for stabilizing soil and creating 'rock pads' during installation. Needle punched nonwoven polypropylene geotextile fabric with a random, three-dimensional pore structure and a uniform, felt-like consistency, high tensile-strength fabric enhances soil stability and controls erosion. Virtually indestructible; unaffected by hydrocarbons amp; freeze-thaw cycles.

What size liner do I need?
The basic formula will work for ALL pond shapes sizing a pond liner is:
[(Pond Length') + (2 x Pond Depth') + (2') = Liner Length'] amp; [(Pond Width') + (2 x Pond Depth') + (2') = Liner Width']
For 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] amp; [(7') + (2 x 3') + (2') = 15' Wide]
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 across, 7' at the shortest length across, 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.
