Imagine basking in the summer heat while floating in your above-ground pool when disaster strikes and the structure gives way. It may look like something out of a comedy sketch, but an unlevel above-ground pool can actually collapse.

We’ll explore the funny and serious sides of this pool situation here.

In order to avoid any unanticipated waterworks, we will discuss when an above-ground pool becomes unsafe and why you should level it.


Can an Above-Ground Pool Collapse If It Is Not Level?

Summer enjoyment is affordable with above-ground pools. If your above-ground isn’t level, your pool may leak and flood your yard and home. Will an unlevel above-ground pool collapse?

A tilted above-ground pool will collapse. Due to the weight of the water, an above-ground pool with a three-inch slope every ten feet can break.

Installing and maintaining pools properly protects your investment. Don’t be discouraged by shoveling. Water weight is one of the main reasons an above-ground pool can collapse if it is not level. Above-ground pools’ walls can handle a certain amount of water.

However, if the pool is not level, the water weight will not be equally distributed, putting excessive stress on some pool walls. The pool may fail if the walls crack or collapse under strain.

Structural problems might cause an above-ground pool to collapse if it is not level. If the pool is not on level ground, it can shift, straining the frame and supports.

This weakens the pool’s structure over time, making it more likely to collapse. Uneven pools can also stretch or tear the liner, reducing stability.

Unlevel above-ground pools can also cause drainage concerns. If the pool is not level, water may collect at one end, raising one side and lowering the other.

This imbalance may stress the pool walls, causing collapse.

Uneven water levels can also influence the pool’s circulation, filtration, and water quality, which might weaken it and cause it to collapse.

When Does an Above-Ground Pool Become Unsafe?

Signs of an Unsafe Above-Ground Pool:

  • Visible Damage To Pool Walls: It is one of the first symptoms that your above-ground pool may be dangerous. Cracks, bulges, and rust are examples. Damages degrade the pool’s structure, making it more likely to collapse.
  • Excessive Leaks: Constant pool leaks may indicate underlying issues. Leaks can degrade the ground beneath the pool, creating a slope above the recommended limit.
  • Uneven Pool Deck: An uneven pool deck may indicate ground movement or erosion. The pool may become unstable and collapse.
  • Leaning or Bowing Pool Walls: This indicates structural vulnerability. Erosion, faulty installation, and aging can cause this.


How Does Water Affect Unleveled Above-Ground Pool?

Unlevel above-ground pools can cause problems, so keeping them level is important.

Liner Tears

Liner tearing is a common problem with unlevel above-ground pools. The pool liner, made of sturdy plastic, can handle thousands of gallons of water.

However, uneven pools stress the liner unevenly. This can break liner seams, causing leaks and water damage.

Wall Collapse and Damage

Unlevel above-ground pools can cause wall collapse.

Above-ground pool walls support the pool structure. Walls break and collapse when water levels rise unevenly.

This can distort the pool and flood your yard. When the pool is unlevel, one wall exerts excessive pressure, straining the framework.

Poor Filtration and Efficiency

Filtration and water circulation require a level above-ground pool. The pool’s slope can cause air pockets in the filter. The filter may miss cycles or lose power to push water through the system.

Inadequate filtering impacts water quality, clarity, and filtration system maintenance and damage.

Safeguarding Pool Usability

Keeping your above-ground pool level is important for safety and to prevent damage. Children and others who may fall into an unlevel pool are at risk.

Uneven surfaces make it hard to balance the pool’s chemicals, which could harm swimmers.

Leveling Above-Ground Pools

Maintain a level above-ground pool to prevent the difficulties above.

This includes carefully prepping the ground before installation, using the right leveling tools, and frequently checking and correcting the pool’s level.

Professionals or manufacturer instructions can help level a pool.


Will An Above Ground Pool Collapse Without Water?

A dry above-ground pool can collapse. An empty pool loses its major support. The pool’s water equally distributes weight and pressure, stabilizing the building. Wind and temperature can damage the pool without water.

Winds can collapse an empty pool. The walls are heavily pressured by strong gusts. Winds can force against the pool walls without water, potentially buckling or collapsing them.

Extreme temperatures can collapse an empty pool. The sun’s heat can stretch pool materials.

The pool’s structure contracts and becomes brittle in freezing temperatures. Constant expansion and contraction weaken walls and cause collapse.

Empty pools may dissolve from the inside. This could happen in hot weather or if the pool is heated. The pool’s interior shrinks and weakens when it melts. The pool may collapse.

Plan ahead to avoid empty above-ground pools collapsing. If you need to drain the pool for maintenance or repairs, move it away from direct sunshine and high winds. This reduces structural deterioration.


What Is The Impact Of Different Slopes Of Unleveled Surface Below Above-Ground Pools?

If pool owners want to make sure their pools last and work properly even if the ground around them isn’t perfectly flat, they need to learn how different slopes affect their pools.

Zero Degree Incline

A one-inch slope in an above-ground pool might not seem like a big deal at first, but it might get much worse if nothing is done about it. A one-inch slope can still have severe effects, even if the normal error margin for skilled installers is 18 to 1/2 inch.

The pool’s surface may become somewhat unlevel, which, if left unchecked, might cause water to collect in one spot and eventually cause structural damage.

Incline of Two Inches

When the incline is two inches or more, people start to take note. There will be an unbalanced water line in the pool as the water rushes to one side.

Pressure on the pool’s walls will rise dramatically, raising the risk of structural damage. This can endanger the pool’s structural integrity and the safety of its users.

Incline of Three Inches

The pool is clearly quite unlevel, sloping by three inches –  the pool’s walls will expand, changing its overall shape.

An unbalanced water supply can also negatively impact the filtration system, decreasing water circulation and possibly exposing some of the jets. The pool’s usefulness and the users’ satisfaction may suffer as a result of these problems.


How Leveled Does A Pool Need to Be?

Even experienced pool installers can’t level a circular pool within 1/8 inch. Oval pools usually have 1/4-inch levelness. This proves levelness perfection is nearly impossible.

However, pools should be level within an inch. At this level, the pool water may look wrong, which is unattractive. Pool levelness should be 1/4 to 1/2 inches for aesthetics.

Pools can withstand a 2 1/2-inch level variation without damage. The water level is clearly uneven.

This disparity may not harm the pool, but it should be addressed to maintain its attractiveness.

Any level differential over 3 inches is harmful and demands quick care. When the level differential approaches 3 inches, thousands of pounds of pool water will apply excessive pressure on one side, creating an imbalance.

To avoid more issues, correct this imbalance immediately.


How Do You Properly Level A Pool?

To properly level a pool, you should follow these step-by-step instructions:

Find The Right Spot

Choosing a spot that is already relatively level is the first step in correctly leveling a pool. It will be a huge help in terms of efficiency. Digging out the area for your pool may require professional or heavier equipment, such as a tractor if the terrain is too uneven.

Take Out the Rocks!

Sod cutters, rototillers, and shovels can be used to remove grass from the area that will become your pool. Also, sweep the area clean of any trash or rocks that could cause injury. In order to keep your pool liner in one piece, a smooth surface is essential.

Make Use Of A Leveling Aid

You can use a line level or a long, straight board to make sure the ground is even. Lay the board flat on the ground and check its levelness with a spirit even.

You might also hammer a wooden stake into the ground near the pool and attach a string to it. Cross over with the string, drive another stake into the earth, and sloppily attach the string to it.

Adjust the height of the string on the stake until it is level using a line level placed on the string in the middle of the area.

Even the Playing Field

To make the ground as level as feasible, dig and add soil to the trouble spots after you’ve pinpointed them. Any additional soil should be carefully compacted. If the pool area isn’t completely flat, readjust the boards and strings as needed.

Consider Using Mason Sand

Before installing a pool, many people choose to cover the soil with at least two inches of mason sand. Mason sand aids in the thorough removal of any rocks or debris that can puncture the pool liner.

Spread the sand out evenly using a rake or shovel, and then use water to compact it. After it has had a chance to harden, use a lawn roller or plate compactor to fully compact the area.

Keep in Mind the Need For A Base Protector

A base protector should be used even if sand has been used to prevent the liner from being punctured and heat loss from the water.

You can use a tarp or some felt, or you can buy cushions designed specifically for swimming pools. On the other hand, a pool pad will keep your pool warmer and safer from the elements.


How Can You Prevent Above Ground Pools From Collapsing?

Below we will discuss in detail the steps you can take to prevent above-ground pools from collapsing.

Installing Correctly

Proper installation is the first and most important step in preventing above-ground pool collapse. This involves leveling and clearing the pool site of sharp objects and debris that could damage the pool liner.

Pool Leveling

Uneven ground is a leading cause of above-ground pool collapse. To equally distribute weight and prevent wall tension, the pool must be level. Before installing the pool, level the ground with a level.

Following Instructions

Follow the manufacturer’s directions carefully when installing your above-ground pool. Each phase ensures pool structure.

Skipping or mistaking a step might weaken the pool and increase the chance of collapse. Take your time and double-check each instruction for correct assembly.

Correct Upkeep

Regular maintenance helps prevent above-ground pool collapse. Look for leaks, cracks, and rust. Repair or replace broken parts immediately.

Maintain pool water chemistry and cleanliness. Improper chemical balance or disregarding regular maintenance can cause pool construction deterioration and collapse.

Pool Winterizing

In cold climates, winterizing your above-ground pool is crucial. Water expands as it freezes, which can collapse pool walls. Drain and cover the pool with a winter cover. This will keep the pool from freezing and collapsing in winter.


Can You Fix A Pool That Has Collapsed?

Actually, you can’t. A collapsing pool cannot be repaired for various reasons. The pool’s structural integrity is immediately jeopardized upon wall collapse.

Fixing pool walls that have fallen down is not only impossible but also dangerous. Factors including ground movement, poor building practices, and natural wear and tear frequently contribute to the collapse. Simply repairing the fallen walls won’t do anything to fix the underlying problems.

Pool walls that have buckled or twisted should be replaced rather than patched.

Temporary solutions, such as wooden blocks or flat pieces of steel to support the afflicted sections, may be recommended by certain sources; however, these solutions are not ideal and may not even work in the long run.

When pool walls buckle or twist, it’s a sure sign of structural degradation; fixing the walls without fixing the underlying problem can just lead to further problems in the future.

The weakened walls will continue to disintegrate over time, even if you manage to stabilize them briefly.
