What Is Structural Pool Crack Repair

A swimming pool is a source of relaxation, enjoyment, and escape from the summer heat. However, even the most well-built pools can develop structural cracks that can lead to significant problems if addressed over time. Structural pool crack repair is a specialized process that focuses on identifying, assessing, and fixing these cracks to restore the integrity and functionality of the pool.

Common Issues and Signs of Damage in Concrete Swimming Pools

Concrete swimming pools, while durable, can experience structural damage over time. Both potential buyers and current owners of concrete pools must be aware of the potential problems and signs of wear. Addressing these issues is essential to prevent further complications and ensure the safety and enjoyment of pool users.

Cracked Concrete Pools

Cracks in concrete pools are a common issue, but they don’t necessarily indicate structural failure. Most often, these cracks only penetrate the surface layers such as plaster, gel coat, or liner and do not reach the leak points or cause leakage problems. However, they can contribute to algae growth or calcium nodules’ formation.

If the cracks in the pool plaster are minor, they may be repairable. However, more severe issues may require full pool replastering, which can be costly. It is essential to assess the extent of the cracks and consult with a professional to determine the best course of action.

Cracked Structure

Structural crack in the pool shell can occur anywhere along its length or circumference, including corners and the skimmer area. Unlike surface cracks, structural damages can lead to leakage that worsens over time. Initially, you may notice increased water loss before identifying the exact location of the leak.

When a structural pool crack is present, it is crucial to repair them promptly to prevent further damage. Consult a pool professional who can assess the extent of the cracks and recommend appropriate repair measures. Ignoring structural cracks can lead to more severe problems and costly repairs down the line.

It is essential to regularly inspect your concrete swimming pool for any signs of damage, such as cracks, leaks, or changes in water levels. Early detection and timely repairs can help prevent further deterioration and extend the lifespan of your pool.

Causes of Cracking in Concrete Pools

Cracking in concrete pools can occur due to various factors, and understanding the causes can help prevent or address the issues effectively.

Poor Construction or Engineering Design

Inadequate construction practices or design flaws can contribute to cracking in concrete pools. Suppose the pool is not built correctly or the engineering design is faulty. In that case, it can lead to structural weaknesses and increased vulnerability to cracking.

Ground Movement and Shifting Soil

Improperly compacted soil around the pool can lead to ground movement, causing the shell to shift and crack. This can occur due to shifting soil conditions, unstable foundations, or inadequate compaction during construction. Groundwater pressure and seismic activity can also contribute to the pool structure’s ground movement and subsequent cracking.

Freezing and Thawing

In regions with freezing temperatures, the expansion and contraction of water during freezing and thawing cycles can exert significant pressure on the pool structure. If the pool is constructed with substandard materials or inadequate reinforcement, it becomes more susceptible to cracking under these conditions.

Temporary Repair Options for Structural Pool Crack

While injecting polyurethane or epoxy and using hydraulic cement injection or stapling can provide temporary fixes for cracked concrete pools, it’s important to note that these methods may not address the underlying issues or provide long-term solutions. They can be cost-effective measures to mitigate immediate problems but should be considered temporary fixes.

Polyurethane or Epoxy Injection

Injecting polyurethane or epoxy into the structural pool crack can temporarily repair and seal them preventing further water penetration. These materials are relatively cost-effective and can provide a short-term solution to minimize water leakage. However, they may require periodic reapplication as they can deteriorate over time.

Hydraulic Cement Injection

When injected into cracks, hydraulic cement can expand and effectively seal them. This method can be cost-efficient and provide a temporary fix to prevent water infiltration. However, it is essential to recognize that hydraulic cement is not a permanent solution and may require additional repairs in the future.


Using rebar staples can stabilize and prevent cracks from reopening. This method reinforces the damaged areas, reducing the likelihood of further cracking. Stapling is a relatively affordable option, with costs typically ranging from $1,000 to over $3,000, depending on the extent of the damage.

Renovation of Damaged Sections

In more severe cases where the pool’s structural integrity is compromised, renovating the damaged sections may be necessary. This involves extensive repair work and can incur higher costs. The expenses associated with renovation depend on factors such as the contractor hired and the extent of the repairs needed.

It’s important to understand that these temporary repair options should be considered interim measures to address immediate issues. It is recommended to consult with a professional pool contractor or engineer who can assess the extent of the damage and recommend appropriate repairs or renovations.

Determining Surface or Structural Cracks in Your Concrete Swimming Pool

Identifying whether the cracks in your concrete swimming pool are surface or structural crack can help you determine the severity of the issue and the appropriate course of action to repair them. Here are some steps you can take to make an initial assessment:

Inspect the Pool Waterline

Examine the waterline of your pool, both above and below the water surface. Look for any visible cracks or fissures along the waterline. Cracks that are present at or below the waterline may indicate structural issues.

Monitor Water Loss

Pay attention to the rate of water loss in your pool. If you notice significant and rapid water loss, it could be an indication of structural cracking that is causing leaks. Remember that some water loss is expected due to evaporation. Still, excessive and unexplained water loss should be a cause for concern.

Observe the Cracks

Surface cracks in the pool plaster often appear as smaller clusters or spiderweb-like patterns. These cracks are typically superficial and do not penetrate the underlying structure of the pool. On the other hand, structural damages are more severe and can be more comprehensive, longer, or deeper. They may extend beyond the plaster and affect the underlying concrete shell of the pool.

Check for Peeling Plaster

Surface cracks in the plaster may cause the plaster to peel away, revealing the underlying concrete. Suppose you notice peeling or flaking plaster but the concrete beneath appears intact. In that case, it suggests surface cracking rather than structural damage.
