The Benefits of EPDM Pond Liners
Apr 19th 2024
When it comes to building a durable, long-lasting pond, choosing the right pond liner is critical. EPDM pond liners provide a number of benefits over standard models. One of the most popular and reliable choices for homeowners and professional installers alike is the EPDM pond liner.
Known for its strength, flexibility, and fish-safe properties, this type of liner is ideal for a wide range of pond applications—including koi ponds, water gardens, and even custom-designed features. Aside from being pre-cut and designed for ease of transport, they can also be used in the construction or renovation of a variety of ponds and water gardens.
How Do EPDM Pond Liners Work?
EPDM stands for Ethylene Propylene Diene Monomer. It is a type of rubber which is synthetic, and exceptionally flexible. Many pond owners have become fond of it because it is easy to handle yet lasts a long time and is safe to use with water.
EPDM pond liners differ from regular pond liners in that they can be shaped in any manner desired. This means they can fit into ponds of all shapes and sizes. They will not harm fish, plants or other aquatic species. Furthermore, these types of pond liners are resistant to certain types of attacks from string algae and microbes and after installation are largely maintenance free. These liners are available in different sizes, and those who want something specific can simply choose the desired measurement when making their order.
Whether you're working on a backyard water garden or a more complex koi pond, EPDM pond liners offer the adaptability needed for precise installations. Most come pre-cut in a variety of sizes and are available with optional underlayment to improve performance and stability.
How Long Will EPDM Pond Liners Last?
When you buy these pond liners from a reputable brand, they can last for decades. These liners are exceptionally durable and simple to install. Additionally, they have been designed in such a way where they can handle very high temperatures. Many are designed with materials that are resistant to ultra violet light. They also tend to be thick, which means that they will be capable of holding water for many years to come.
Unlike many pond products today, whose manufacture has been outsourced to developing countries, many EPDM pond liners and accessories are 100 percent made in the USA. This means their design quality and standards are superb. Many of these pond liners are sold with underlayment which has a strength that is high tensile. This is essentially an additional isolation layer that is placed beneath the liner. The underlayment will provide you with a long lasting and stable foundation which can be used with waterfalls, water gardens or Koi ponds.
The Role of Underlayment in Pond Installations
For the best results, pairing your EPDM pond liner with a strong underlayment is highly recommended. This additional layer sits between the liner and the soil, offering increased protection against sharp rocks, air voids, and shifting ground. It not only stabilizes the base of the pond but also extends the lifespan of the liner itself.
Underlayment also helps during installations involving waterfalls or custom features, ensuring that your entire ecosystem remains structurally sound and leak-resistant.
What You Should Look For When Purchasing An EPDM Pond Liner?
You should look for pond liners which are capable of handling temperatures extending from -40 Fahrenheit to 175 degrees Fahrenheit. They should have resistance to UV light, and should also be certified as being safe for both plants and fish. Getting an EPDM liner with an extra layer for underlayment is a plus, as it will stabilize the soil while blocking air voids from being created among the soil and liner.
The liner you buy should also be resistant to punctures yet light in weight, which will allow it to be carried and transported with ease. Depending on the texture that the liner has, it might also be capable of reducing the growth of algae while simultaneously promoting the growth of healthy bacteria.
Whether you're working with a small backyard pond or a large koi pond, choosing the right EPDM pond liner ensures your aquatic environment is both beautiful and built to last.
