The better and solid it is, the higher your pond’s chances to thrive.

Here are some factors that you need to consider to ensure that you can make the right choice.

Material – the base material used in the pond liner is one of the first things you need to check. The thickness, overall cost, and longevity will depend on the material. Go for materials that are ozone and UV resistant.

Thickness – measured in mils, you want to get a balanced thickness because the thicker the liner is, the heavier it is. If you want something lighter though, you might be compromising the durability of the pond liner.

Durability – your pond liner will always be exposed to sunlight, water pressure, and temperature fluctuations. You don’t have any control over these because it is Mother Nature calling the shots. You must make sure that your choice of pond liner can withstand these uncontrollable factors.

Installation – if you are planning to do this yourself, make sure that you can install it with ease and without the need for special tools. Usually, pond liners come in rolls so you must get the dimensions right before starting to unfold it else you just created a bigger problem.

Size – when shopping for your future pond liner, you must know the exact measurements of your pond. Estimates won’t work.

What is a Pond Liner?


A fish pond is always a nice addition to any garden. Unfortunately, not all have the luxury of a natural fish pond.

Thanks to pond liners, you can now have a so-called man-made fish pond, and with the correct plants and rocks to beautify it, you can achieve an almost natural look.

A pond liner is impervious storage specifically designed to hold liquids, in this case, the fish pond water. The corner of a pond liner is rolled over the top of a soil slope then secured in an anchor ditch. Alternately, it can also be fixed on a vertical wall that is made of concrete or wood. Pond liners are also generally manufactured in rolls.

Types of Pond Liners

Pond liners can help you unleash your creativity when it comes to designing your pond. It gives you that liberty to add a few more elements to your fish pond without sacrificing the efficiency of your pond liner. Based on material, here are the different types of pond liners: EPDM pond liner, RPE pond liner, 3D pond liner, and PVC bond liner.

EPDM pond liner – this is made from rubber and is known for its elastic that is solid and hard-wearing. Usually, this material does not have any softeners on it. It is also acid rain and UV radiation resistant. EPDM is normally used in water basins and roofing materials and lately is being used in ponds. The EPDM version for ponds though is crafted to be safe for fishes and plants. You don’t need to worry about the poisonous substances that can damage to your pond plants and fishes.

RPE pond liner – RPE or reinforced polyethylene liners is a top favorite because it is nearly 3x stronger but 1/3 the weight of an EPDM. The materials used for this are thicker and it is more cost-effective. One drawback for RPEs though would be its bendability characteristic. Since the material used is thicker, then you must be willing to compromise on its pliability.

3D pond liner – this type of pond liner is slowly becoming the top option among pond owners. A 3D pond liner is a bag derived from the EPDM but is modified and personalized specifically to the size and form of your pond. This entails you not need to remove any existing pleats. You also don’t need to make your pond liner to size and stick it by yourself. You are only required to identify the correct dimensions of your pond and everything else afterward will be handled by your 3D pond liner supplier.

PVC pond liner – a little different from EPDM and 3Dpond liners, the PVC liner uses a material that is smooth that it can easily adjust itself to whatever form your pond has. The material used in this PVC liner can be welded but still be glued if necessary. If you need to make repairs, there are special PVC pond liner glues that are available. This type of liner should last you for a good couple of years but it not resistant to UV radiation. It will be best not to have it directly under the brutal sunlight.

These three have their unique cons and pros as pond liners so it is greatly up to you to determine which one would suit your needs and preferences.

Why Do You Need Pond Liner?

A pond liner is the easiest way for you to create a fish pond in your terms. You need a pond liner because it prevents the water from leaking or seeping out of your pond. As much as possible, you want no leaks because all the significant nutrients like magnesium, calcium, and selenium can escape away with the water.

Also, to sustain a pond with a bottom that is natural, you need to constantly add water to it. This might not be a huge deal especially at the start but with the continuous water loss, replenishing the water two or three times a week can be a real inconvenience. With pond liners, you don’t need to worry about this routine.

You also need a pond liner because it also acts as a barrier so contaminants cannot enter the pond. The water will not mix with the soil surrounding it and you have more control over keeping your pond water clean. It is an essential part of your pond because you don’t need to worry about chemicals from bug sprays and fertilizers from contaminating your pond water. You can keep the environment of your fishes and plants healthier.

Lastly, it’s best to have a pond liner because it can help prevent erosion from happening around your pool especially if you have a natural bottom. The ever-changing temperature and the rain can cause the pond’s edges to wear away and in time can alter the size and shape of the pond.
