Swimming pools are a great way to cool off during hot summer days and provide a fun place for family and friends to gather. However, a common problem that can occur with inground pools is that they become unlevel. This can happen for a variety of reasons, including ground settling, soil erosion, and improper installation. An unlevel pool not only looks unappealing but can also be dangerous, causing injuries or even property damage. In this blog post, we will provide you with a comprehensive guide on how to fix an unlevel inground pool.
How to Fix an Unlevel Inground Pool?
Step 1: Identify the Problem
Before you can start fixing your unlevel pool, you need to identify the problem. A simple way to do this is to use a long, straight object like a level or a string to check the water level at different points around the pool. If the water level varies by more than an inch, your pool is unlevel.

Step 2: Drain the Pool
Once you have identified the problem, the next step is to drain the pool. You can do this by using a submersible pump or siphoning the water out of the pool using a hose. It is important to drain the pool slowly and gradually to avoid any damage to the pool’s structure.

Step 3: Prepare the Site
After draining the pool, you should prepare the site for leveling. This involves removing any grass, dirt, or debris from around the pool area. It is also important to remove any rocks or stones that could cause damage to the pool liner.
Step 4: Level the Pool
The most common method used to level an inground pool is to use a process called “slabjacking.” This involves injecting a mixture of sand and cement underneath the pool’s base to raise it to the desired level. A professional contractor with experience in pool leveling should perform this process.
One can use another method, which involves digging out the high spots around the pool to lower them to the level of the low spots. This method is more labor-intensive and can be more expensive.

Step 5: Refill the Pool
You can begin refilling the pool with water once you have leveled it. Again, it is important to do this slowly and gradually to avoid any damage to the pool’s structure. You should also use a pool water test kit to check the water’s chemical balance and adjust it as necessary.

Step 6: Check for Leaks
After filling the pool, you should check for leaks. You can do this by using a pool leak detection kit or by visually inspecting the pool for any signs of water leakage. If you detect a leak, it is important to have it fixed immediately to avoid any further damage to the pool.

Step 7: Reinstall the Pool Equipment
The last step is to reinstall the pool equipment, including the pump, filter, and skimmer. Checking all the equipment for any damage or wear and tear and replacing any parts that need to be replaced is important.

Tips for Preventing an Unlevel Inground Pool
Here are some tips for preventing an unlevel inground pool and avoiding the need for costly repairs.
- Hire a Professional: When it comes to installing an inground pool, it is important to hire a professional who has experience in pool installation. By properly preparing the site, leveling the ground, and installing the pool, a professional contractor ensures that the job is done correctly from the start.
- Regular Maintenance: Regular maintenance is crucial to preventing an unlevel pool. This includes keeping the pool clean, checking the chemical balance of the water, and inspecting the pool equipment for any signs of wear and tear.
- Avoid Heavy Traffic: Heavy traffic around the pool area can cause soil erosion and settling, leading to an unlevel pool. Encourage swimmers to use the pool steps to enter and exit the pool instead of jumping or diving, as this can cause the pool to shift.
- Keep the Area Free of Debris: Leaves, dirt, and debris can cause the ground around the pool to settle, leading to an unlevel pool. Regularly clean the area around the pool to prevent debris buildup.
- Monitor the Soil: Keep an eye on the soil around the pool and watch for any signs of settling. If you notice any sinking or shifting, contact a professional contractor immediately to have it addressed before it causes damage to the pool.

By following these tips, you can prevent an unlevel pool from occurring and avoid the need for costly repairs. Remember, regular maintenance and monitoring of the pool area can go a long way in preventing problems in the future.
If you do notice any signs of an unlevel pool, don’t hesitate to contact a professional contractor to have it addressed before it causes further damage.
