Liners are crucial when it comes to maintaining water bodies like dams and pods. Choosing the right liner is more important than you might think and it’s vital to opt for one that suits the needs of the specific water body the most. Whether you’re creating a tranquil backyard pond or working on a large-scale commercial project, an EPDM pond liner will serve you well.
EPDM liners are a type of synthetic rubber that work wonders for waterproofing ponds and dams. In this blog, we’re exploring these kinds of liners in more detail and unpacking what makes them a great addition to a water body. Let’s dive in!
What is an EPDM Liner?
EPDM stands for Ethylene Propylene Diene Monomer and is a synthetic rubber that’s highly waterproof. Originally, people used the material in industrial settings but over time, it’s gained the gold standard for waterproofing water bodies like ponds and dams. The reason why it’s viewed in such high regard? It’s extremely waterproof, highly durable, tough, flexible, and long-lasting.
What Are the Benefits of EPDM Liners?
Unmatched Durability
One of the main reasons why people lean towards EPDM liners is the excellent durability they have. Unlike plastic and PVC, EPDM doesn’t become brittle or weak over time. Whether it’s cold, hot, wet, or dry, EPDM liners will stand strong.
Plus, this durability is backed by real-world examples. In a set of agricultural reservoirs in Spain exposed to intense sun and temperature variations, the very first EPDM liners were installed back in the 1970s. Impressively more than 50 years later, those original liners are still in place, flexible, intact, and performing just as they did when they were first installed.
That kind of longevity is hard to beat and not many materials compete with that.
If you’re based in Australia, you know how brutal the weather can be and the negative impact it can have on a water body. But, EPDM is up to the challenge. Being UV and ozone resistant, EPDM also manages to stay performing in subzero temperatures as well as when it’s incredibly hot.
Rollgum, manufactured in Spain and our EPDM liner of choice, is engineered to maintain its look, quality, and integrity even in extreme temperatures ranging from –40°C to +150°C. While others fail, Rollgum retains its shape and performance for decades, even through tree root pressure and ground movement.
Excellent Flexibility
The natural flexibility of EPDM pond liners is one of their standout benefits. Whether you’re lining a tight, curved garden pond or a large rural dam with uneven contours, EPDM liners easily mold to the shape you need. Offering an unrivalled 400% stretch, their flexibility stops them from cracking and tearing, making the installation process so much easier even if it’s your first time doing it.
Due to this flexibility, Rollgum EPDM liners are manufactured in Europe and used all across Australia. If your waterbody has features like sharp corners and rocky edges, Rollgum will still easily slip into place. So, if you live rurally or need an off-grid installation, this is a great option.
Another great thing about Rollgum is how easy it is to cut and join together. You don’t need any welding equipment or heavy machinery. With just sealant glue, splicing tape, and a roller, you can securely connect two sheets with ease. This level of flexibility simplifies installation, as well as secures the watertight seal that will hold up in place.
Environmentally Friendly and Fish Safe
Choosing the right liner is essential when building a pond that supports aquatic life because you have a better chance of maintaining a healthy ecosystem. Non-toxic, chemically inert, and completely safe for fish, plants, and other pond life, EPDM liners are the top choice.
Cheaper plastic liners can release harmful chemicals into the water as they break down over time, causing harm to all living things in the water body as the decayed material ends up in the water. But, EPDM maintains its integrity without releasing any harmful substances, keeping koi, goldfish, or any kind of species, safe and able to thrive.
EPDM also doesn’t harm the pond’s plants or soil biology, helping to create and maintain a balanced ecosystem where everything can flourish. Versatile enough for use in irrigation purposes and safe for swimmers, it adds yet another layer of benefits to its already impressive qualities. If you’re eco-conscious, EPDM is the best choice, not just for pond performance but also for sustainability, offering long-term environmental benefits.
Long-Term Cost Savings
When you’re browsing liners, you might feel put off by the higher upfront cost of EPDM liners. Yes, they’re the more expensive option. However, the long-term saving costs are significant as the material has got an excellent life expectancy of 20-50 years. But, you can expect it to last longer and even outlive you with proper care.
Rollgum EPDM comes with a 20-year warranty, but in reality, it will most likely outlast that. In fact, you can expect it to serve you for decades, far beyond the usual lifespan of other materials.
How do you save costs with EPDM liners? The main reasons are:
- Minimal maintenance is necessary
- Fewer repairs over time due to its excellent durability
- Less water loss from leaks thanks to its unmatched flexibility
Not just a durable choice, but a smart one for your wallet as well, EPDM can save you thousands in maintenance costs and water conservation over the lifespan of your pond or dam.
Long-Term Waterproofing Performance
Water retention is the main feature of a dam or pond liner, and it’s absolutely crucial. EPDM provides a completely watertight barrier that holds its integrity for decades, as opposed to compacted clay which can shrink and crack in dry conditions, or cheaper plastic liners that become brittle over time.
For you this means minimal seepage and more consistent water levels throughout the year. EPDM is great for retaining every drop, making sure that your water stays where it’s supposed to. So if you need your water body for livestock, firefighting, irrigation, or recreation, it’ll work wonders.
In addition to its incredible waterproofing ability, EPDM is highly resistant to punctures, root intrusion, and weathering, making it ideal for long-term water storage and drought-proofing.
Final Thoughts: Choose EPDM for Peace of Mind
EPDM is the obvious choice if you want a pond liner that lasts and performs for as long as you need it. From small backyard ponds to large-scale dams, it’s the smartest option for any water feature thanks to its unmatched durability and flexibility.
Choosing an EPDM liner means less maintenance, fewer problems, and peace of mind that your pond or dam will keep performing year after year, whether you’re a weekend DIYer or managing a rural property.
