Can a Gunite Pool Pop Out of the Ground?

Gunite pools are renowned for their durability and structural integrity. However, like any structure, there is always a possibility of unexpected events occurring. Understanding the factors that may cause a gunite pool to pop out of the ground is crucial in ensuring the longevity and safety of your pool.

How Does a Pool Pop Out of the Ground?

Pool pop-outs can result from a combination of various factors, such as hydrostatic pressure, inadequate drainage, extreme weather conditions, and poor soil conditions. The intricate relationship between these elements can lead to the gradual or sudden displacement of a pool.

What causes a Pool to Pop Out?

1. Soil Conditions and Hydrostatic Pressure:
   • Erosion of soil beneath the pool due to inadequate compaction or water seepage.
   • High water table levels, especially during heavy rainfall or flooding, exerting hydrostatic pressure on the pool walls and floor.
2. Inadequate Drainage and Pool Maintenance:
   • Improper installation or malfunctioning of drainage systems, which can lead to water accumulation around the pool.
   • Negligence in maintaining the pool’s water balance and chemical treatment, resulting in excessive pressure within the pool structure.
3. Natural Disasters and Extreme Weather Conditions:
   • Earthquakes, which can cause ground movements that result in pool displacement.
   • Severe frost or freeze-thaw cycles leading to the expansion and contraction of the soil, destabilizing the pool.

Understanding Gunite Pool Construction

To fully grasp the possibility of a pool pop-out, it is essential to comprehend the construction process of a gunite pool.

The Process of Building a Gunite Pool

Building a gunite pool involves several key steps:

1. Excavation: Digging a hole to the desired pool shape and dimensions.
2. Structure Framing: Constructing a steel framework, known as rebar, to provide structural reinforcement.
3. Plumbing and Electrical: Installing the necessary plumbing and electrical components for the pool’s filtration and circulation system.
4. Gunite Application: Spraying a mixture of sand, cement, and water, known as gunite, onto the rebar framework to create the pool shell.
5. Finishing Touches: Applying a finish such as plaster, tile, or aggregate to complete the pool’s interior.

Factors That Contribute to Pool Pop-Outs

While gunite pools are designed to withstand various forces, several factors can contribute to the possibility of a pool pop-out. Let’s explore these factors in detail.

Soil Conditions and Hydrostatic Pressure

The soil surrounding a pool plays a vital role in its stability. Factors such as soil type, compaction, and water table levels impact the risk of a pool pop-out.

In regions with clay or expansive soils, poor compaction during the excavation process can leave gaps that allow water to accumulate beneath the pool. The hydrostatic pressure from this trapped water can gradually push the pool out of the ground.

Inadequate Drainage and Pool Maintenance

Proper drainage is crucial to prevent water accumulation around the pool. Inadequate or malfunctioning drainage systems can result in hydrostatic pressure build-up and increase the risk of a pool pop-out.

Regular maintenance of the pool’s water balance and chemical treatment is also essential. Water imbalances can lead to the deterioration of the pool’s structure, weakened walls, and potential displacement.

Natural Disasters and Extreme Weather Conditions

Natural disasters and extreme weather events can pose significant risks to pool stability. Earthquakes can cause ground movements, leading to structural shifts that result in pool pop-outs.

Additionally, severe frost or freeze-thaw cycles can cause the soil to expand and contract, destabilizing the pool over time. It is crucial to consider the region’s climate and potential weather events when assessing the risk of a pool pop-out.

Signs and Risks Associated with Pool Pop-Outs

Recognizing the early warning signs of a pool pop-out is crucial for timely and effective intervention.

Identifying Early Warning Signs

1. Uneven Pool Deck: The pool deck may appear uneven, showing signs of an uneven pool structure below.
2. Cracked or Shifting Tiles: The tiles surrounding the pool may crack or shift due to ground movement, indicating a potential pop-out.
3. Bulging Walls: The walls of the pool may start bulging outward, a clear indication of hydrostatic pressure build-up.
4. Separation of Coping or Decking: Separation between the pool coping, which covers the pool’s edge, and the deck may occur due to a pool pop-out.

Potential Damage to the Pool and Surrounding Areas

When a pool pops out of the ground, significant damage can occur. Apart from the structural implications, neighboring structures, such as fences or landscaping, may also be affected. The risks associated with a pool pop-out extend beyond the pool itself, making prompt action necessary.

Can a Gunite Pool Be Left Empty?

Leaving a gunite pool empty for an extended period can increase the risk of a pool pop-out. Without adequate water to counterbalance the hydrostatic pressure, the pool shell may experience outward displacement.
