Benefits of Using Liner For Your Pond

The main function of a pond liner is to prevent water from seeping out of your pond. The dripping water removes important nutrients such as calcium, magnesium and selenium from the pond.

To maintain a pond with a natural soil, you must constantly add water to it. While this may not be a major problem with a small pond, the water loss can be quite significant with large ponds, and topping up the water several times a week can be a burden.

A liner not only protects against water leaving the pond, it also acts as a barrier to prevent contaminants from entering. Because the water does not mix with the surrounding soil, you have more control over the water values ​​and you keep your pond clean.

Another bonus is that you don’t have to worry about fertilizers, bug sprays, or other chemicals seeping through the soil and into your pond. Having this control over the purity of your water can help maintain a healthier environment for your plants and fish.

Pond liners also prevent erosion around your pond. If you use natural soil, rain and varying temperatures can wear down the pond’s edges, which over time can significantly change the shape and size of the pond.

 

How to Determine the Size of Your Pond Liner

There are many calculators available online to help you determine how much plant cover you need. That said, it helps to know how to figure it out for yourself to better understand the size and shape of your pond.

This calculation is not as easy as you may think. You must consider the depth of all bends at the bottom of the pond, as well as along the banks, and you must leave enough overlap to install the liner correctly.

When calculating the dimensions of your pond, it is very important where you get your measurements from. Make sure you get the width at the widest point, the length at the longest point, and the depth at the deepest point.

This will likely give you a measurement that is slightly larger than the actual dimensions of your pond, unless you have one that is perfectly square, rectangular, or perfectly round, which is a good thing. If your sizes were smaller, the liner wouldn’t fit.

Once you have the dimensions of your pond, you will need to perform two simple calculations to determine the size of the liner you need:

To know the length:

Pond length at the longest point + double depth + 2 for overlap

To calculate the width:

Pond width at widest point + double depth + 2 for overlap

Here are some examples.

If your pond is 11 feet long x 8 feet wide x 2.5 feet deep, this is what you would do to determine the size of the liner:

Width: 8 (width) + 5 (double depth) + 2 = 15

Length: 11 (length) + 5 (twice the depth) + 2 = 18

So, in this example, you’ll need 15 x 18-foot siding. For ponds that are not a standard size, order one that is larger but closer to the actual size. For example, a 10×20 liner would be too small, but a 15×20 liner would be perfect.

Here’s another example. Let’s say your pond is 2 meters long, 1 meter wide and 2 meters deep. In this case, your calculations are as follows:

Width: 4 (width) + 4 (double depth) + 2 = 10

Length: 7 (length) + 4 (twice the depth) + 2 = 13

For this pond you need a liner of at least 10 x 4 meters. A 10×12 eyeliner would be a bit too small so you should use a 12×15.

 

How to Install a Pond Liner in a Large Pond?

The first thing to do before you can install a pond liner is dig the hole for your pond. Some people prefer to lay a garden hose to plan the shape so that you have a better idea of ​​where to dig.

When digging the hole, keep the bottom as flat as possible. If you want one end to be deeper than the other, it is better to create a gradual slope than a big step down.

After digging the hole, measure it according to the instructions above to make sure you get the correct size liner.

It is a good idea to install an underlayment under the cladding. This is a thicker layer of material that insulates the bottom of the pond from rocks or sharp roots trying to pierce the surface. Once this is done you are ready to install the siding.

1. Spread the liner over the top of the hole. Then push it into the hole by walking to the center. Cover the bottom of the pond first, working your way to the edges, making sure to leave an even overhang around the edge of the pond.

2. Once the bottom is covered, move around the edges, fold the siding if necessary and use large stones, bricks or stones to hold it in place.

3. When you are satisfied with the appearance of the liner, add about two inches of water to cover the bottom of the pond. The liner will likely move if the weight of the water pushes it down. If necessary, remove anchors from the sides to allow the siding to cure naturally.

4. Trim a liner that extends more than a foot or more from the stone ring that holds it in place. This will remove the mass to keep the pond looking tidier. Depending on the size of your pond, it may require quite a bit of pruning. (Save the pieces you cut to use as patches later if needed.)

5. Complete the landscape around the pond by adding more rocks and stones to the edge to add more security to the liner.

6. Add plants and the pump to the pond and then fill it.

Obviously, the installation process for a preformed siding is a bit different. The main difference is that you should not start digging your pond hole until you have the liner.

1. Place the preformed liner where you want the pond. Spray around the perimeter with line marker spray. You can also use sand to create an outline.

2. Dig a hole 4 to 5 inches larger than the pond’s perimeter. Start by digging only to the depth of the plant shelf.

Once you’ve dug about a foot, place the pond in the hole and press the center. This marks in the dirt where you need to keep digging to reach the correct depth.

4. Continue digging until the pond fits in the hole. Make sure the bottom is level as much as possible. Once the pond is in place, fill it halfway with water.

5. Now is not the time to fill in the area around the pond. Fill this in with topsoil, rocks, stones or sand. You can also pour cement around the edge so that you can seal the pond after the concrete has dried.

Put plants in your pond. Ideally, about one to two thirds of the area should be covered with plants.

7. Connect and prime the pump.

 

Which Pond Liner is Best?

Ultimately, the best pond liners for your pond depends on the aesthetics you want to achieve, your pond design, and the weather conditions around your home.

Greenseal and Firestone EPDM liners, as well as HDPE pond liner, are versatile solutions for almost any pond, although you should use an underlay if you choose EPDM liners.

For pond builders with a limited budget, Beckett PVC liner is an economical option; Keep in mind that this is the least durable of the coatings we reviewed.

Finally, the Algreen Pond Kit is a good solution for people who just want a small preformed pond without the hassle of designing and building a pond from scratch.
