Introduction

An unlevel inground pool can be more than just an eyesore; it can pose significant safety and structural risks if left unaddressed. From uneven water levels to potential structural damage, the consequences of pool unleveling can be far-reaching. In this guide, we’ll explore the essential steps to fix an unlevel inground pool, ensuring it regains its stability and functionality. By understanding the importance of addressing this issue promptly and following a systematic approach to repairs, pool owners can enjoy a safer and more aesthetically pleasing pool environment. From assessing the problem to completing necessary repairs and maintenance, restoring an unlevel pool requires careful attention to detail and a commitment to long-term pool care.

How to Fix an Unlevel Inground Pool

To fix an unlevel inground pool, begin by draining the pool if necessary and gathering the required tools and materials, including a transit or laser level. Assess the extent of the problem by identifying signs of unleveling and determining potential causes such as ground shifting or poor construction. Use the leveling equipment to adjust the pool supports or add support where needed, gradually filling the pool with water and checking for levelness. Finally, address any surrounding structures and perform regular maintenance to prevent future issues.

Structural Integrity of an Inground Pool

The advantage of leveling and stabilizing inground pools is the preservation of the pool’s structural integrity. When the pool’s foundation shifts, the weight and pressure of the water distribute unevenly, putting more stress on some areas of the pool walls and floor.

Uneven surfaces can cause cracks and weakening of the structure, leading to damage that may require expensive repairs. Expanding polyurethane foam fills voids and stabilizes concrete, improving weight distribution and preventing more settling.

A level base also plays a critical role in preventing leaks. Uneven surfaces can lead to gaps or breaches in the pool liner, causing water to seep out. These leaks not only waste water but can also undermine the surrounding soil or concrete, leading to further instability. Maintaining a stable base for your inground pool is paramount for its structural integrity, reducing the likelihood of costly repairs or replacement in the long run.

Uneven surfaces in and around the pool can lead to tripping hazards, increasing the risk of slips or falls. Sometimes, voids form under the plastic or fiberglass steps in the pool, causing the steps to flex or bow. In many cases, concrete leveling can fix this problem. When the underlying concrete base of your pool is uneven, it can cause stress and cracking to the pool coping due to uneven pressure distribution. Damaged coping can allow water and debris to infiltrate the pool shell, potentially causing substantial harm.

A pool with a solid foundation will endure the test of time and require less attention to repairs and upkeep, saving homeowners time and money in the long run.

Identifying Signs of an Unlevel Pool

Identifying signs of an unlevel pool is crucial to addressing the issue effectively. One common indicator is uneven water levels around the perimeter of the pool, which may be visible upon visual inspection. Additionally, bulging or sinking areas in the pool’s structure can suggest uneven settling or shifting.

Using a transit or laser level can provide precise measurements to confirm unevenness in the pool’s surface. Gaps between the pool edge and surrounding structures may also indicate a lack of levelness. Taking note of these signs early on allows for prompt intervention to prevent further damage and ensure the pool’s safety and functionality.

  1. Visual Inspection: Look for any noticeable changes in the pool’s water level around the perimeter. Signs of an unlevel pool include uneven water levels, bulging or sinking areas, and gaps between the pool edge and surrounding structures.
  2. Measuring: Use a long straightedge or laser level to check for inconsistencies in the pool’s water level. Measure the distance between the water surface and the straightedge at various points around the pool to identify areas of unevenness.

B. Determining the Extent of the Problem

  1. Depth Measurement: Measure the depth of the water at different points in the pool to determine if there are significant variations in depth.
  2. Checking Pool Structure: Inspect the pool’s structure, including the walls and floor, for any signs of cracking, bulging, or settling. These can indicate areas where the pool has shifted or settled unevenly.
  3. Assessing Surrounding Structures: Examine the deck, coping, and surrounding landscape for any signs of settling or unevenness that may be affecting the pool’s level.

C. Potential Causes of Pool Unleveling

  1. Ground Shifting: Soil movement due to erosion, settling, or seismic activity can cause the pool’s foundation to shift unevenly.
  2. Water Saturation: Excessive water accumulation in the soil around the pool can lead to uneven settling and pool unleveling.
  3. Poor Construction: Improper installation or inadequate support during the pool’s construction can result in structural issues that contribute to pool unleveling.
  4. Tree Roots: The growth of tree roots near the pool can exert pressure on the surrounding soil, causing it to shift and the pool to become unlevel.
  5. Climate Factors: Freeze-thaw cycles, extreme weather conditions, and temperature fluctuations can also impact the stability of the pool’s foundation over time.

Preparing For Unlevel In-ground Pool Repairs

Preparing for repairs is a critical step in addressing an unlevel inground pool. It begins with gathering the necessary tools and materials, including leveling equipment such as a transit or laser level, as well as any additional support materials like shims or concrete mix.

  3. Materials: Concrete mix, sand, gravel, shims, wooden blocks, pool wedges, and other leveling materials.
  4. Safety Gear: Work gloves, safety goggles, ear protection, and appropriate footwear.

B. Ensuring Safety Precautions are in Place

  1. Clearing the Area: Remove any obstacles or debris from around the pool to create a safe working environment.
  2. Securing the Pool: Erect temporary fencing or barriers around the pool area to prevent access during repairs, especially if draining the pool.
  3. Electrical Safety: If working with electrical equipment or pumps, ensure power sources are turned off and outlets are safely covered.
  4. Handling Chemicals: If draining the pool, handle pool chemicals according to manufacturer guidelines and dispose of them properly.

C. Draining the Pool (if Necessary)

  1. Assessing Water Level: Determine if draining the pool is necessary based on the extent of the repair work and the current water level.
  2. Drainage Plan: Plan for proper drainage of the pool water to prevent flooding or damage to surrounding areas.
  3. Using a Pump: Use a submersible pump or drain system to remove water from the pool efficiently.
  4. Safety Precautions: Follow safety guidelines when working with pool drains and pumps to prevent accidents or injuries.

Leveling an In-ground Pool

Leveling the pool is a meticulous process that requires careful attention to detail. Firstly, utilizing a transit or laser level is crucial to identify low spots and areas of unevenness on the pool’s surface accurately.

Once identified, adjustments to the pool supports or the addition of support materials such as shims or concrete blocks may be necessary to achieve proper leveling. Gradually filling the pool with water while continuously monitoring for levelness ensures that adjustments are made effectively. It’s essential to repeat adjustments as necessary, as achieving a perfectly level pool may require several iterations.
