5 Reasons That Causes Uneven Inground Pool

1. The Ground Has Shifted:

The most common reason that pools become unlevel is because the ground around them has moved. This can be caused by things like floods, earthquakes, or even just the natural expansion and contraction of the ground over time. If you live in an area where any of these things are common, you should have your pool inspected regularly to make sure it is still level.

2. The Pool Wasn’t Built Level:

Sometimes pools are not built level due to human error, but this can usually be corrected relatively easily. However, if the pool was installed by a professional, it’s worth getting in touch with them to see if they can rectify the situation.

3. The Pool Has Sunk:

Pools can gradually sink into the ground over time if they are not properly supported. This can happen for several reasons, including poor drainage, leaks, or even just the weight of the pool itself. If you notice that your pool is starting to sink, it is important to take action immediately to avoid further damage.

4. Problem With Pool’s Pump or Filter:

If the pool’s pump or filter isn’t working right, the water level can become uneven. This can happen with above-ground or inground pools. If you see that the water level in your pool isn’t the same all around, you should check the pump and filter to make sure they’re working like they should.

5. Bad Water Chemistry:

If the water in your pool is not properly balanced, it can cause the pool to become unlevel. This is usually due to a lack of chemicals, such as chlorine, in the water. Therefore, it’s important to regularly test the water in your pool and add chemicals as needed to maintain a balanced pH level.

How to Fix Unlevel Inground Pool: 17 Effective Steps

Step 1: Gather Necessary Tools and Materials

To fix an unlevel inground pool, you will need the following tools and materials:

  • Long 2×4 lumber or a long straightedge
  • Carpenter’s level or a laser level
  • Shovel
  • Tamping tool or plate compactor
  • Wheelbarrow
  • Sand or soil (depending on the type of pool)
  • Landscaping fabric (optional)

Step 2: Assess the Pool’s Level

Using a long 2×4 or a straightedge, along with a carpenter’s level or a laser level, determine the extent of the unevenness in your inground pool. This will help you identify the areas that require leveling and provide you with an understanding of the amount of work necessary to correct the issue.

Step 3: Drain the Pool

Before beginning any leveling work, drain the pool completely. This will allow you to access the pool floor and make any necessary adjustments without the interference of water.

Step 4: Identify the High and Low Spots

Using your level, identify the high and low spots in the pool floor. Mark these areas with a waterproof marker or another form of visible identification. This will help you target the specific areas that require attention during the leveling process.

Step 5: Remove High Spots

Using a shovel, remove the high spots in the pool floor by digging out the excess material. Be sure to dig carefully and avoid puncturing or damaging the pool liner. Place the excess material in a wheelbarrow for disposal or relocation.

Step 6: Fill Low Spots

Fill the low spots in the pool floor with sand or soil, depending on the type of pool you have. If you have a vinyl liner pool, use sand; if you have a concrete or fiberglass pool, use soil. Spread the material evenly using a shovel, and then tamp it down using a tamping tool or a plate compactor. This will help create a firm, level surface for the pool floor.

Step 7: Recheck the Level

After filling in the low spots and removing the high spots, use your level to recheck the pool floor. If any areas are still uneven, repeat steps 5 and 6 as necessary until the entire pool floor is level.

Step 8: Install Landscaping Fabric (Optional)

If desired, install landscaping fabric over the leveled pool floor. This can help prevent weeds from growing through the pool liner and provide an additional layer of protection between the pool floor and the liner.

Step 9: Reinstall the Pool Liner

Once the pool floor is level, reinstall the pool liner according to the manufacturer’s instructions. Ensure that the liner is properly seated and free of wrinkles or air pockets.

Step 10: Refill the Pool

Refill the pool with water, ensuring that the water level is consistent around the entire perimeter of the pool. Monitor the water level as the pool fills to ensure that the pool remains level and does not shift.

Step 11: Inspect the Pool’s Surrounding Area

In addition to leveling the pool floor, it’s essential to inspect the surrounding area of the pool. Check for any unevenness or settling in the decking or patio area, as this can also contribute to an unlevel pool. If necessary, make adjustments to the surrounding area to ensure that it is level and stable.

Step 12: Perform Regular Maintenance level pool. 

Regularly test the pool water for pH, alkalinity, and sanitizer levels, and make any necessary adjustments to maintain the recommended levels. Proper water chemistry can help prolong the life of your pool and ensure that it remains level and stable.

Step 13: Monitor Pool Water Chemistry

Maintaining proper pool water chemistry can help prevent damage to your pool liner and other pool components, which can contribute to an unlevel pool. Regularly test the pool water for pH, alkalinity, and sanitizer levels, and make any necessary adjustments to maintain the recommended levels. Proper water chemistry can help prolong the life of your pool and ensure that it remains level and stable. 

Step 14: Keep the Pool Area Well-Drained

Proper drainage around the pool area can help prevent soil erosion and settling, which can contribute to an unlevel pool. Ensure that your pool’s drainage system is functioning correctly and that water is directed away from the pool and surrounding structures. This will help maintain the stability of the pool area and prevent future leveling issues.

Step 15: Inspect Pool Equipment and Accessories

Regularly inspect your pool’s equipment and accessories for signs of wear, damage, or shifting. This includes the pool pump, filter, ladder, diving board, and any other components that may impact the pool’s levelness. Replace or repair any damaged equipment as needed to maintain the stability of the pool.

Step 16: Watch for Signs of Soil Erosion

Soil erosion can cause the pool to become unlevel over time. Keep an eye on the surrounding landscape for signs of erosion, such as gullies, exposed tree roots, or areas where soil has been washed away. Address any erosion issues promptly to maintain the stability of the pool area and prevent further unevenness.

Step 17: Consider Professional Assistance

If you are unable to fix an unlevel inground pool on your own or if the problem is severe, consider hiring a professional pool contractor. They have the expertise and equipment necessary to accurately assess and correct an unlevel pool, ensuring that the issue is resolved safely and efficiently.
