There is always the frustration after first buying or creating your above-ground pool and then filling it up with water.

But what if the ground is not leveled?

You definitely do not want your pool starting to lean to one side when you get in it, you need it to be flat to the floor to maximize your experience. 

Are you building your pool and just buying one?

You need to take extra care when it comes to leveling your ground to the pool because you do not want to cause any dangers to your land or surrounding land.

You also need to think about keeping your own pool intact and avoid damage to the lining of your pool. 

If you have already filled up your pool and you have realized that the floor is not stable because it is tilted, you will need to sort this out straight away as it could potentially damage your garden if you continue to keep using it when it is not flat.

Always try and focus on the leveling first to avoid any extra work or effort for yourself.  

Why Are Some Pools Not Flat?

There can be several reasons why you will need to level out the ground in your garden to make sure your pool is safe and flat. Here are some of the reasons for leveling out your pool.

The Ground Is Weak

If the ground in your garden is not strong and hard then the weakness of the ground can affect how much you will need to level out the ground.

You do not want it to sag or tilt and to avoid this, you will need to move or build it on concrete or earthy ground. 

The Land Is Sloping

If you have an area where the land is sloping you will really start to notice when the pool is filled up with water. It can be as little as half a centimeter to affect the tilting of the pool.  

What Are The Risks It Can Have?

You need to measure how much your pool is tilting because if it does not tilt more than a centimeter then it should be ok.

However, if it does start to tilt further than a centimeter then this will cause a problem that needs to be fixed.

By leaving it, you are risking damaging the structure of the pool and if you leave it long enough it could even shatter the liner. 

If anything was to shatter, this could also cause problems with the amount of water that can be released.

This can also be dangerous for the environment and you also need to consider the damage it can cause to other people‚Äôs land if it reaches that far. 

Due to pools also having a high level of chlorine, it also poses a danger to either your garden or a neighbors garden or veg patches and you won’t be able to eat any of it. 

How Unlevel Can You Have Your Pool?

You need to be careful about how unlevel your pool is with the ground because if it exceeds a certain amount then it is something that will need to be fixed as soon as possible. 

If you are looking at under an inch then it is not something you need to be too worried about.

However, you will need to keep an eye on this as it could be increased over time. If it is slightly more than an inch then this is something that causes damage to the lining and structure of your pool.

You will be able to sort this problem out by wedging the pool. 

If you are measuring the level of your pool and it exceeds 1 inch and is edging more towards 2-3 inches then you will need to sort this out straight away.

You will need to empty the pool (see also ‘How Long Can You Leave Your Pool Empty?‘) immediately and take it down as it would be too risky.

You really want to avoid having to go through this process because you have the risk of something breaking and causing you many problems depending on how bad it can get if not sorted. 

How To Solve The Problem Or Avoid

The first thing you need to think about is why the pool is unlevel.

The most common issue is where the ground will be sloping and you won’t be able to have your pool on ground that exceeds the 1 inch unlevel amount.

If you find that it is, you will need to drain the pool immediately and start again, focusing more on the ground itself to make sure it is definitely level before you restart.  

A great way to try and make sure your ground is level is inserting concrete slabs underneath which will make it easier.

By adding in slabs you will be able to sort out the small amount of space you will need to fill to make it level. 


Overall, you need to be careful when you are installing or building a pool to make sure your pool is level enough to not become dangerous.

If you exceed the amount that is advised, you will need to spend more time draining the water and setting it back up after it has been leveled out properly.

Therefore, you need to just take the time to level it out beforehand and make sure it is correct before building to save you the precious time and energy. 

You also need to think about why your pool will not be leveled depending on what type of ground you have in your garden and whether it is strong enough to withstand the pool.

Keep all of these factors in mind if you are thinking about getting a new pool or building one.

You need to especially keep all of this information in mind if you are building your own pool because it would be more difficult to dismantle than one you can just buy. 

Hopefully this guide will help you avoid any problems you may have with your ground and leveling because it is not something that you would have to do all of the time.

Therefore, everyone is a beginner at this type of building and it is always good to remember the importance of this task because it will save you time and money in the long run.
