At the same time, this EPDM rubber pond liner is easy to maintain. There is no need to scrub it or apply special coatings.
Furthermore, it is ready to use right out of the packaging. Simply unfold the liner and install it on your fish pond.
As for the size, it measures 15 feet long and 20 feet wide. As such, this liner can fit medium-sized ponds, fountains, and water gardens. Plus, it is flexible enough for oddly-shaped ponds.
There is also no need to worry about harming your fish or the environment when using this flexible pond liner. It is both fish and environmentally friendly.
Most importantly, reviews for this best pond liner were positive. If there is any critique, it would be the weight, as it can be quite heavy to set up on your own. A few users were also disappointed with the delivery service because the package came crumpled.

How to Choose the Best Pond Liner for Your Needs
By now, you probably have an idea of the best pond liners. But if you still have difficulties choosing the right one for your needs, fret not!
Below, I will discuss the factors you need to consider before finalizing your purchasing decision.
Size
The first thing to consider when choosing a pond liner is how much material you need. To determine this, you must figure out the dimensions of your pond.
Take note of the longest, widest, and deepest points of your pond. Then, double that depth and add one foot to the measurement.
Finally, add this number to both the length and width of your pond. You can now find the appropriate liner size for your needs.
For instance, if you have a pond that is 5 feet deep by 10 feet long by 8 feet wide, the calculation would be:
- (5 feet deep x 2) + 1 = 11 feet
- 11 feet + 10 feet long = 21 feet
- 11 feet + 8 feet wide = 19 feet
Thus, you need to invest in a liner that is 21 feet long by 19 feet wide to cover the entire pond surface area.
Material
Besides the size, you also need to check the material of the pond liner. There are different types of components that pond liners are crafted from. The most common materials are ethylene propylene diene monomer (EPDM) and polyvinyl chloride (PVC).
The former is known for its UV-resistant properties and high flexibility degree. EPDM rubber is also easy to fold, especially around the corners. Most importantly, this material is safe to use around fish, plants, and the environment. The only downside is that it is usually heavier than PVC liners, making it difficult to ship and handle.
In contrast, a PVC pond liner is easy to lay down and install. It is lightweight and flexible, ideal for different types of ponds. However, this material often uses plasticizers to increase malleability, which can harm fish and the environment. Plus, it does not last nearly as long as EPDM rubber pond liners.
Choosing between the two depends on your needs and personal preferences.
Flexibility
You might also want to consider the flexibility of your pond liner. You must ensure that it can be appropriately shaped to align with your pond. Take note that the malleability of the liner largely depends on its material, so you have to choose carefully.
For instance, if you have a kidney bean-shaped or freeform pond, you must look for a flexible liner. It must be easy to shape into the curves and other crevices of the pond.
However, those who have a simple square or circle pond do not necessarily need a very malleable liner.
Safety
Finally, you need to ensure that the pond liner is safe to use for your fish and plants.
EPDM rubber pond liners are fish and environment-friendly. But be careful when choosing PVC liners for your pond. Some of them can contain trace amounts of arsenic and other toxic chemicals. These can be dangerous to fish.
Frequently Asked Questions
Do I really need a pond liner?
It might be tempting to skip using a liner during the excavation phase of your project. However, it is essential to install one.
The pond liner is a waterproof sheet that can keep your pond filled with water. As such, it can also prevent the water from leaching back into the earth. Plus, it protects fish and plants from harmful outdoor conditions.
Overall, a pond liner can ensure that your pond stays beautiful, fresh, and safe for years to come.
Which is better: PVC pond liner or EPDM liners?
The best type of liner depends on your needs and personal preferences.
But if you will ask me, the best type of pond liner uses EPDM rubber. This material can withstand harsh weather and prolonged exposure under the sun. Thus, it can last you for a long time.
How to install a pond liner?
A pond liner is relatively easy to install. If you already own an underlayment, make sure to lay that down first.
Once it is properly secured, you can unfold and roll out the liner along the length of your pond. Make sure that there are no sharp rocks in the vicinity. Then, you can proceed to pull the liner down to the bottom of the pond and up the other side. Afterwards, you can secure the liner by tucking it into the trench. Do not fill the trench until the pond is full of water.
WHen in doubt, follow the manufacturer’s instructions to ensure successful liner installation.
