Pond Liner is the foundation for any Koi pond, water garden, or waterfall. From residential backyard ponds to commercial water features.
45-Mil EPDM LifeGuard Pond Liner is the quality choice of installers and feature owners. UnderGuard Underlayment (NOT included in this listing) protects and promotes longevity of the pond liner. Both work together bringing unmatched quality to your backyard.
LifeGuard Pond Liner Features and Technical Specs:
1. What is EPDM?
EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e. ketones, esters, and alcohols).
2. What is the maximum size sheet for EPDM membrane?
Sheets as large as 50 feet in width are produced mostly for use in ballasted and mechanically fastened applications. Narrower widths are also produced to offer applicators greater flexibility in positioning membrane. Narrower sheets are also produced without factory seams (seamless) for use primarily in adhered and mechanically fastened applications. The major advantage of seamless material is the elimination of factory splice T-joints that occur when factory seams intersect with field splices. This reduction in T-joints significantly increases the potential for watertight performance by eliminating potential "water channels" into field splices. Both narrow and wide sheets are manufactured in varying lengths from 50' to 200'.
3. 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.
4. How Many Gallons of Water does My Water Feature Hold?
Length x Width x Average Depth x 7.48 = Gallons Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is... 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Length x Width x Average Depth x 0.8 x 7.48 = Gallons Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is... 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Length x Width x Average Depth x 7.48 =Gallons Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Length x Width x Average Depth x 0.25 x 7.48 = GALLONS =Gallons Example: 15’ long, 10’ wide and 1.5’ Deep Pond 15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
5. 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.
LifeGuard EPDM Pond Liner adapts to a wide variety of water feature projects. It fits into corners and follows the contours along the sides and bottom of your pond. Attaches easily to waterfalls and skimmers, and readily accepts pipe and hose penetrations without leaks. LifeGuard Pond Liner fits well in ponds with planting shelves. The liner readily fits to skimmers, biological waterfall filters, filter weirs, bottom drains and other types of filters requiring liner attachment.
Creating a safe and healthy environment for fish, plants and wildlife is the goal of every water feature enthusiast.
LifeGuard EPDM Pond Liner has been tested and certified fish and wildlife safe by Guardian Systems, Inc. Test results are available on the manufacturer’s website.
Remains flexible and pliable across a broad temperature range - from +170⁰F to -40⁰F
LifeGuard EPDM Pond Liner resists harmful Sun damage. Can remain exposed to direct sunlight for prolonged periods. Contains no plasticizers which become hard and brittle resulting in cracks and splits.
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.
This listing does NOT include UnderGuard Underlayment Nonwoven Geotextile.
