How To Fix An Unlevel Inground Pool


Having an inground pool in your backyard can provide endless hours of fun and relaxation during the hot summer months. However, if your pool is unlevel, it can not only be an eyesore but also pose safety risks. An unlevel pool can cause water to collect on one side, affect the balance of the pool structure, and potentially lead to structural damage. In this article, we will guide you through the step-by-step process of fixing an unlevel inground pool, ensuring the safety and enjoyment of your swimming experience.

Evaluating the Problem

The first step in fixing an unlevel inground pool is to determine the extent and cause of the problem. Begin by visually inspecting the pool and identifying any areas where the pool deck or coping may be sinking. Use a level tool to check the levelness of the water surface, as well as the pool walls and floor.

Identifying the Underlying Cause

Once you have identified the areas where the pool is unlevel, it is crucial to determine the underlying cause of the problem. Several factors can contribute to an unlevel inground pool, such as poor soil conditions, improper installation, or even natural settling over time.

Seek Professional Assistance

Fixing an unlevel pool is a complex task that often requires the expertise of professionals. It is recommended to consult with a pool contractor or engineer who specializes in pool leveling. They will have the necessary knowledge and tools to accurately assess the situation and provide appropriate solutions.

Determining the Best Solution

After the evaluation by a professional, they will suggest the most suitable solution for your unlevel inground pool. The chosen method will depend on the extent of the problem, the underlying cause, and your budget. Here are some common solutions:

1. Adding Soil or Gravel

If the problem is minor and localized, the pool contractor may recommend adding soil or gravel beneath the affected area. This process involves carefully excavating the area and gradually adding the material until the pool becomes level. The soil or gravel layer creates a stable base that can support the pool structure while preventing further sinking.

2. Pressure Grouting

Pressure grouting is often used for larger unlevel pools. This technique involves injecting a mixture of cement, sand, and water into the ground beneath the pool. The injected grout fills any voids or gaps and creates a solid foundation, leveling the pool in the process. An experienced pool contractor will strategically determine the injection points and monitor the pressure to ensure a precise and controlled leveling process.

3. Underpinning or Jacking

For more severe cases of pool unlevelness, underpinning or jacking may be necessary. This method involves lifting the affected portion of the pool using hydraulic jacks or specialized lifting equipment. Once the pool is lifted to the desired level, additional support systems, such as helical piers or push piers, can be installed to stabilize the pool and prevent future sinking.

4. Pool Demolition and Reconstruction

In extreme cases where the pool structure is significantly compromised or the cost of repairs outweighs the benefits, pool demolition and reconstruction may be the best course of action. This option should only be considered after thorough consultation with a pool professional who can assess the condition of the pool and provide expert advice.


Dealing with an unlevel inground pool requires immediate attention to prevent further damage and ensure the safety of swimmers. By evaluating the problem, identifying the cause, seeking professional assistance, and selecting an appropriate solution, you can restore your pool’s levelness and enjoy a worry-free swimming experience. Remember to consult with a pool contractor or engineer who specializes in pool leveling to ensure the best possible outcome.
