Everything You Need to Know About Choosing the Right Pond Liner

 A serene pond, whether riotously decorated koi home or serene water lily sanctuary, brings irreplaceable loveliness and serenity to a setting. The usability and survival of such a feature of a dwelling, though, rely on the soundness of one irrefutably practical component: the pond liner. Tighter than a standard piece of plastic, a good pond liner is the watertight foundation that holds water in and provides water animals with a level playing field. Exploring downwards into material, then thickness, is how to turn your damp fantasy into reality without becoming a puddle.

Understanding About Pond Liner Materials

There are various materials found in the market with various properties. EPDM (Ethylene Propylene Diene Monomer) rubber would be the most in demand, and most of them use it as a standard within the industry because it's strong and long-lasting. Its strength also makes it an effortless install because it will bend nicely over poorly sized ponds, shelves, and contours. EPDM also has superior resistance to UV radiation, ozone, and harsh temperatures with extended exposure with a life expectancy amore than 20-30 years. You must be able to locate EPDM choices readily available like the very common 45 mil pond liner at big box retailers like Home Depot pond liner sections or shops like pond liner Lowes.

The second most widely used material is PVC (Polyvinyl Chloride). Newer PVC liners have UV inhibitors to stop this, but are less puncture resistant than EPDM or RPE. Reinforced Polyethylene (RPE) is a newer compound and has made significant inroads, especially with big installations.  The material's weight-to-strength characteristic is perfect for easier handling with large projects, and it's very resistant to tear and UV breakdown. Where there is a requirement for maximum folding complexity, it will likely be less inelastic than EPDM, but RPE is stronger and more resistant and is typically as good or superior to EPDM.

The Use of Liner Thickness

Thickness, in terms of "mil" (one mil = one-thousandth inch), is the second most important parameter. While there is always the presumption that more weight material will be superior, the most popular is more significant where long life and puncture resistance are required. A 45 mil EPDM Pond liner lowes for instance, is sufficient for most garden ponds and will be extremely flexible and durable.  A 45 mil EPDM pond liner would be more than sufficient for the "typical" backyard pond with relatively smooth beds.

Where your slope for the pond is hard rock and roots, or where there will be heavy usage or burrowing, an EPDM with extra thickness or a very puncture-resistant RPE would be the best investment. Large ponds require heavier liners to distribute more hydrostatic pressure over time. Always consider possible hazards at your location in deciding on thickness. 

How to Determine the Proper Size

The right liner size prevents wastage or shortfalls in compounding. The formula for liner size is:

Length = (Maximum Pond Length) + (2 x Maximum Pond Depth) + (2 x Overlap for Edging).

The "Overlap for Edging" would typically be applied to edging at the liner edge, typically 1 to 2 feet on both sides, in a quest to secure it and give a natural finish.

Use of Underlayment

Subject to liner thickness or material, a quality pond liner underlayment should be utilized for long-term purposes. This underlayment product, one such widely used non-woven geotextile, creates a strong barrier between the excavated subgrade and the pond liner itself. It offers protection against puncture of the liner by hard rock, roots, or even soil particles moving beneath. A quality underlayment, most notably by industry experts such as Singhal Landscape Geotextile, may even be able to lengthen your pond liner's lifespan and prevent costly leaks.

 Factors in Installation

Most pond liners, particularly EPDM, are tolerant but still need to be properly installed.

Ensure the pond bed is cleaned clean of any hard material following excavation. Roll out underlayment uniformly and roll the liner slowly along the prepared surface. Place the liner into natural shape in the pond without tugging or stretching.  Force out large wrinkles, beginning from the center and working outwards. Cut only the surplus liner when filling the pond and after settling for a minimum of a day or two to enable you to offer a good overlap where to clamp edges.

Conclusion

A best pond liner is the optimal one that renders your water feature handsome, healthy, and durable.

By working towards compounding the attributes of other materials like EPDM, PVC, and RPE, selecting the ideal thickness, getting your size right, and most importantly, installing an underlayment for protection, you are setting yourself up to succeed at your pond. Whether buying a 45 mil pond liner at Home Depot's pond liner display or buying specialty items from distributors like Singhal Landscape Geotextile, an informed decision today will pay benefits for years of enjoyment in your water paradise.

FAQ

Q: Can roofing EPDM rubber be used as a pond liner?

 A: NO - don't even think about it. While roofing EPDM and EPDM pond liner look identical, roofing EPDM contains fungicides, fire retardants and many other poisonous chemicals that are toxic to aquatic plants and fish. Always make sure you purchase a pond grade EPDM liner specifically designed for aquatic uses; this protects your fish and plants the best it can.

Q: Who is the largest manufacturer of Pond Liner?

A: No single "best" manufacturer dominates the global pond liner making as there are many large scale and numerous local manufacturers of pond liners. Firestone Building Products has been long term an industry leader with its "Firestone PondGard" EPDM pond liners among the top manufacturers in the world. There are also many industry leading manufacturers of PVC, RPE, and HDPE liners, among other pond liner production methods, that are also based globally. Some are even Indian companies, like Singhal Landscape Geotextile which is a popular source of geotextile and pond liner products.
