How To Get Wrinkles Out of a Pond Liner

To avoid wrinkles in your pond liner, taking it slow and careful is very important. After you have laid your pond liner in the hole, slowly fill it with water using your hands to push any wrinkles towards the edges of the pond. The weight of the water will stop the wrinkles from coming back. Continue doing this until the wrinkles have been worked up and out of the pond.

That’s the quick version of it, keep reading for more details.

Why Remove Wrinkles From Your Pond Liner?

There are a few good reasons as to why it is important to know how to get wrinkles out of your pond liner:


The first reason is obvious; large wrinkles are ugly, especially if your pond is shallow and you can see the bottom.

Wrinkles Trap Debris

The second, and probably more important reason, is that wrinkles trap debris. If your pond is quite large and features a bottom drain, then you want any debris that falls to the bottom of the pond to flow down towards the bottom drain, any wrinkles in the pond liner will stop this from occurring.

Avoid Wrinkles in your Pond Liner

The first step to avoiding wrinkles in your pond liner is to follow the correct installation methods. You can see a full guide here on installing a flexible liner garden pond, but we will go through the basic steps required to avoid wrinkles here.

When Filling Your Pond with Water

Slowly fill your pond with water. As the water covers the wrinkles, use your hands and feet to push any wrinkles in the pond liner to the side walls. The weight of the water will prevent the wrinkles from returning.

Don’t fill the pond too fast as you need to take your time with this and it’s easy for the pond to get too full before you have removed as many wrinkles as possible. You will be tempted to turn the hose up and work faster, but I highly recommend taking it slowly.

It helps to have someone helping you with this, as one person can pull the liner up to remove the wrinkles while the other smooths the liner out with their hands.

Depending on the shape of your pond, it will likely be easiest to do this by working in circles, moving from the center outwards.

Don’t forget to pull the slack out of the pond walls as you go.

Managing Sidewall Wrinkles in Your Pond Liner

No matter what you do, you will not be able to have your pond walls completely wrinkle-free. What you can do, is manage these wrinkles by consolidating them into larger folds.

Round pond liners can be folded at regular intervals, square liners can be folded into the corners.

You will need to do this as the pond nears being full of water so that the liner is held into place. You can also use pond tape to help.

Cover Up Remaining Pond Liner Wrinkles

As I mentioned, depending on the shape and size of your pond, it may not be possible (or even required) to get rid of all the wrinkles in your pond liner. In these cases, you can follow these tips to hide the wrinkles as much as possible.

  1. I am having a problem with my liner, the pond has been in for about 16 years
    and 3 years ago there was a leak, we have a company come in that was repairing
    our retaining wall and said his guys could fix it, the day they cam I was away
    it looked good, but whenever I have to drain the pond to clean it out for winter
    or in the spring, the liner balloons out and crowds out the bottom, my pond is
    about 7 ft long (curved a bit ) and 3.5 ft wide and 38″ deep, when it balloons
    out the fish etc a sort of crushed and some fish, and I can’t pressure wash the
    the bottom, is there an easy solution, I tried to press the liner back, maybe I
    need to drain as best and then get into the pond as it showed in you website.
    will the liner stay there even if I drain it.
