How to Level an Above Ground Pool with Water in It

Summer is here, and you can finally use your above ground pool in the backyard that has been sitting unattended all year. However, you notice the foundation seems shifted, and the water sits uneven on the walls of the pool. It is a good thing you have caught this sooner than later.

Not to worry, we will show you how to level an above ground pool with water in it. The tilt of your above ground pool can lead to a shift of weight on one side of the walls, leading to eventual collapse. Rather than draining the water entirely and rebuilding the pool, there is an easier way. With these eight simple steps, you can level your above ground pool for a safe and fun summer!

1. Measure the Tilt

The first step in learning how to level an above ground pool with water in it is to measure the tilt in a matter of inches or degrees. This will give you a good estimate of how severe the tilt is and how fast you need to act. If your pool is off by one inch, there may be a quick fix by adding more pool water. However, if your pool tilts to one side by 2 inches or more, there is a greater possibility of a collapse of the walls. You can use a ruler or level to measure the distance. 

2. Drain Some Water

The second step in leveling your above ground pool is to drain a partial amount of water. This will allow you to lift the sinking side of the pool more easily. We recommend draining enough water to where the pool is halfway full of water or enough to where it is liftable. 

3. Remove the Blocks

After draining, the next step is removing any hard blocks under the slab. Many pool owners place cement or concrete blocks under the base of the pool for stability. Remove any blocks only under the side of the pool that is lowered down into the ground. This will get rid of any instability in the pool’s foundation and allow for a fresh one. We recommend using a jack for easy lifting. 

4. Replace Blocks 

Replace the old block you just removed under the pool’s base with a fresh cement or concrete block under the pool slab. A fresh block will allow better stability under the pool’s weight, especially if the old one has been damaged or cracked. The block(s) should be tall enough to raise the lowered end to the same height as the remainder of the pool. We recommend using a hammer or any adequate tool to put the block into place. Add as many blocks as necessary to raise the lowered part of the pool. 

5. Repeat 

Continue replacing old blocks with new ones, enough to raise the height of the lowered side of the pool. Complete this task on as many areas of the pool as necessary. It is important that you are keeping an eye on the evenness of the above ground pool from all sides. We recommend carrying a ruler or level to determine the straightness. 

6. Fill the Hole

After replacing the cement or concrete blocks around the lower side of your above ground pool, you may notice an empty area of space. There will most likely be a hole that needs to be filled with some sort of filling. We recommend filling this hole with soil and spraying it with water to allow everything to flatten out. The soil can be packed with a shovel or rake. 

7. Test the Blocks 

Continue the process of packing in the soil underneath the areas below the pool that need filling. When everything looks as even as possible, you can remove the jack used to lift the above ground pool. This is the time to test the blocks and see if all sides of the pool look even. 

8. Refill Your Pool 

After all the previous steps are completed and successful, you can now refill the remainder of your pool with water. Keep an eye out for a tilt of more than an inch. If all the steps have been carefully done, you should be ready to get back into your above ground pool. Repeat any steps necessary to align your pool as perfectly as possible before completely refilling.

How to Level an Above Ground Pool with Water in It: Conclusion

Leveling your above ground pool can be done successfully in just a matter of a few steps. All you need are a few tools and some extra help to align everything back into place. We stress the importance of installing your above ground pool carefully in order to have everything well leveled. However, nothing is perfect, and the ground may shift over time. In any case, keep an eye on the alignment of your above ground pool. We want a fun and stress-free summer for all above ground pool owners to enjoy!
