How To Level A Swimming Pool

Importance of Proper Pool Leveling

Proper pool leveling is crucial for maintaining the integrity and functionality of your swimming pool. A level pool not only enhances the aesthetic appeal but also ensures optimal performance and safety. In this article, we will delve into the details of why proper pool leveling is essential, explore the benefits it offers, and provide a step-by-step guide on how to level your pool effectively.

Understanding the Basics

Before we dive into the discussion on leveling a pool, let’s first understand what exactly it means. Pool leveling refers to ensuring that all sides and corners of your swimming pool are at an equal height from the ground surface. When a pool becomes unlevel due to various factors such as ground settling, soil erosion or wear over time, it can lead to several issues.

Ground Settling: One common cause of an unlevel swimming pool is ground settling. This occurs when there are changes in moisture content or shifting soils beneath your property.

Soil Erosion: Another factor affecting your pools’ levelness is soil erosion. Over time, water runoff can wash away soil around or under your swimming area.

Pool Age and Wear: As pools age or experience heavy use over time, they may become uneven due to natural wear and tear on different parts of their structure.

Signs of an Unlevel Pool: It’s important to be aware of signs that indicate whether or not your swimming area needs leveling.
– Uneven Water Levels: If you notice that one side has consistently higher water levels than another side even after balancing chemical levels regularly.
– Cracks in The Pool Structure: Structural cracks can occur if there are areas where pressure isn’t evenly distributed throughout.
– Difficulty Maintaining Water Chemistry: An unlevel surface makes it challenging for chemicals like chlorine or other sanitizers used in treating pools from being adequately dispersed throughout its depths.

Preparations and Safety Measures

To begin with any task, it’s essential to gather the necessary tools and equipment. Here are some items you will need:
– Leveling Device: A laser level or water level can be used to determine if your pool is unlevel.
– Shovel: You may need a shovel to remove excess soil or grass from the pool area.
– Sand or Gravel: Filling low spots with sand or gravel helps in leveling out uneven areas around your swimming area.
– Wooden Stakes: These stakes will help mark different points on the ground during the leveling process.

Ensuring safety precautions before starting any pool-related tasks is crucial. Follow these measures:
1. Turn off all pool equipment: This includes pumps, filters, heaters, and any other electrical devices connected to your swimming area.
2. Drain the Pool Partially: Lowering the water level below halfway helps make adjustments easier by reducing weight on its structure while ensuring there’s enough water for visual reference during leveling.
3. Secure The Pool Area To Prevent Accidents: Close off access points like gates and fence entrances so that no one accidentally falls into an empty or partially filled swimming area.

Assessing The Pool’s Current Level

Now that we have prepared ourselves let us move forward towards assessing our pools’ current levels.

Using a Leveling Device:

There are two main methods you can use – laser level method and water level method.

Laser Level Method:

Setting up The Laser Level:

To start using a laser level, place it on a stable surface outside of your pool but within sight of all corners. Ensure it is leveled itself by checking its bubble indicator before proceeding further.

Measuring The Pool’s Slope:

With your laser setup correctly, measure distances from each corner point of interest (preferably along sides) back towards where you set up this device; write down measurements obtained at every corner marked until completion across entire circumference marking done throughout evaluation phase using tape measure when needed. These measurements will help you identify the high and low points in your pool.

Water Level Method:

Setting up The Water Level:

To use a water level, attach one end of a transparent tube or hose to an object placed on the edge of your pool (e.g., valve). Make sure it is securely fastened so that there are no leaks during measurement process. Place other end where you can easily see water levels while keeping it parallel with the ground surface as much as possible.

After assessing your pools’ current level, let us now discuss how we can correct any irregularities.

Leveling The Ground:
1. Removing Excess Soil Or Grass: Use a shovel to remove any excess soil or grass from areas where you want to achieve better leveling.
2. Filling Low Spots With Sand Or Gravel: Add sand or gravel into lower spots until they’re filled adequately enough for them not being too deep compared with surrounding surfaces but also without creating higher ridges around those same locations either – aim for smooth transitions between different parts within these target zones.
3. Tamping Down Filled Areas: Using tamper tool, compact fill material like sand/gravel by applying downward force on it repeatedly across each spot individually until they become firm enough underfoot.

Adjusting The Pool’s Supports:
1.Identifying Support System: Determine which type of support system your swimming area has – concrete blocks, piers, etc.
2.Adding/Removing Supports As Needed: Based on support system identified above add/remove necessary supports at specific areas requiring adjustments ensuring stability throughout structure’s foundation while maintaining overall alignment guidelines given manufacturer if applicable due considerations such factors like environmental conditions play role here too since some materials might react differently depending upon their exposure levels related elements present outside said structures e.g wood rotting when exposed moisture long periods without proper care maintenance practices followed by owners/users etc..
3.Ensuring Proper Alignment And Stability: Double-check that all supports are properly aligned and secured, ensuring stability throughout the structure’s foundation.

Rechecking The Pool’s Level:
1. Using The Leveling Device Again: After making necessary adjustments, use your leveling device again to ensure you have achieved a level surface.
2. Making Necessary Adjustments If Needed: If any areas still appear uneven or out of level after rechecking with the leveling device, make further adjustments as required until desired results are achieved.

Finishing Touches

After successfully leveling your pool, it is important to complete the process by following these steps:

Refilling The Pool:
1. Ensuring Proper Water Chemistry: Before refilling your pool with water from a hose or other source, make sure to balance its chemical levels appropriately.
2. Monitoring Water Levels During Refilling: As you refill the pool, keep an eye on water levels and adjust accordingly.

Checking For Leaks Or Cracks:
1. Inspecting The Pool Structure: Once filled back up check for leaks or cracks in your swimming area’s structure visually by observing signs such as wet spots along surfaces within said structures indicating potential problem areas requiring attention may need repair work done professionally if severe enough cases arise where immediate action becomes necessary due risks associated ongoing usage risk posing safety hazards users swimmers alike given their magnitude seriousness involved here when considering consequences involved possible repairs needed alongside costs incurred during time frame since leaving them unresolved can lead worsened conditions demanding even more expensive solutions eventually becoming costly endeavor better avoided altogether at least long term maintenance care management strategies implemented early stages instead having deal issues cropping repeatedly later part owning/operating pools..
2.Repairing Any Damages Found: In case of any damages found during inspection patch them up using appropriate repair materials available at local stores designed specifically repairing swimming area related components according guidelines set forth manufacturers concerned providing detailed instructions how go about doing repairs safely effectively without causing further damage themselves structures associated parts if done incorrectly otherwise could result worsening condition mentioned above costing significant amounts money trying rectify later stages operation ownership said pools.

Regular Maintenance and Monitoring:
1. Periodic Checks For Levelness: It is essential to periodically check the levelness of your pool to ensure that it remains in good shape.
2. Addressing Any Issues Promptly: If you notice any signs of an unlevel pool or encounter other problems, address them promptly to prevent further complications.


In conclusion, proper pool leveling is crucial for maintaining a safe and enjoyable swimming experience. By following the step-by-step instructions outlined in this article, you can ensure that your pool remains level and functional throughout its lifespan. However, if you feel unsure or lack the necessary expertise, it is always advisable to seek professional help from contractors with grading experience or construction professionals who specialize in swimming pools.

Remember, a level pool not only enhances safety but also improves water circulation and heat distribution while preventing structural damages such as cracks or leaks. So go ahead and take the necessary steps to keep your pool leveled for optimal enjoyment!
