Dependent on use, pond liners are warrantied for anywhere between 5 and 25 years—though BTL liners typically last much longer. Here’s how you can extend the life expectancy of your liners or repair, reuse, or recycle pond liners.
Extend the Life of Your Pond Liners
Sharp objects, abrasive chemicals, or inclement weather can prematurely damage liners. But there are precautionary measures that can be taken to extend the life of your existing pond liners.
Purchase Quality Liners
When it comes to water liners and geomembrane containment systems, material matters. At BTL, we manufacturer custom liners made from reinforced polyethylene (RPE), reinforced polypropylene (RPP) and low-density polyethylene (LDP). Our RPE and RPP liners are stronger, provide better puncture and tear resistance, are lighter weight and have excellent UV resistance when exposed to sunlight.
Geomembrane containment systems and water liners made from RPE, RPP and LDP provide superior water loss prevention, soil and erosion control, protect against contamination and prevent seepage. Contact BTL Liners for more information about which material would be best for your water liners project.
Avoid Using PVC Pond Liners
PVC pond liners are heavier and less UV resistant than geomembrane systems and pond liners which make PVC liners far easier to puncture. As pond liners constantly come in contact with the sun, UV protection is critical to maintaining quality and durability and substantially decreases the chance of discoloration, viscosity changes, cracking, and loss of adhesion.
Unlike the weaker PVC materials used by our competitors, our RPE and RPP liners don’t require a geotextile underlayment when placed over raked dirt, even if it contains rounded rock. Extremely high puncture resistance means our RPE and RPP liners are some of the most versatile LEED liners on the market.
Install Liners Correctly
When you are first installing a pond liner, comb through the soil beneath it to ensure there are no sharp protrusions or foreign objects. Items that penetrate from beneath the liner are the hardest to fix later on so it’s important not to skip this step. Then install liners over well-compacted soil.
Use Cold Weather Liners When Applicable
Most pond liners are designed to withstand temperatures as cold as -40 degrees Fahrenheit, but extreme weather conditions could cause those liners to crack. BTL Cold Weather Liners are tested to -85 degrees Fahrenheit and provide extra protection against cracking, puncturing, and abrasion from harsh chemicals and cold weather climates.
Reuse Pond Liners
Before you recycle pond liners, see if you might be able to reuse them.
Use as an underlayment: Just because a pond liner has aged doesn’t mean it can’t still be used. Drain the pond then install the new liner directly over the old liner for an additional layer of leak protection.
Donate to a friend: If a portion of your pond liner has become unusable, check with a neighbor to see if they might have a smaller pond that could use the undamaged portion of your pond liner.
Upcycle: BTL Liners can take on a second life when upcycled as planter liners, waste containment containers, compost liners, stormwater containment, or any other use in which water, oil, or liquids needs to be contained with watertight plastic.
Recycle Pond Liners
BTL liners are made from double-scrim reinforced polyethylene (RPE) material that can be recycled similarly to other plastic materials. Contact a polyethylene recycling company such as Polychem USA to see how you might be able to recycle pond liners or sell your old RPE liners.
BTL and PPL are much stronger (much better puncture and tear strength), lighter weight (larger factory panels), excellent UV resistance (exposure to sunlight) and less expensive than most of the competition. In fact, the BTL -40’s 1200+ PSI puncture strength is the highest we are aware of for any product even remotely close to the price range of these products.
The need for underlayments has been virtually eliminated in most applications of our liners. Unlike the weaker PVC and EPDM, the extremely high puncture resistance of our liners means that they don’t require a geotextile underlayment when placed over raked dirt, even if it has rounded rock in it. Puncture of the liners from underneath is virtually unheard of.
