Dealing with Cracks in Your Swimming Pool
5 min read

Owning a swimming pool is a dream come true for many homeowners. It's a place to unwind, host gatherings, and create lasting memories with family and friends. However, the appearance of cracks in your beloved pool can quickly turn that dream into a nightmare. Cracks in swimming pools are not uncommon, and Gunite pools, known for their durability, are not immune to this issue. In this comprehensive guide, we'll explore how to deal with cracks in your swimming pool, with a focus on Gunite pool crack, so you can take the right steps to preserve your aquatic oasis.

Understanding Gunite Pools and Their Susceptibility to Cracking

Gunite pools, also referred to as concrete pools, are a popular choice among homeowners due to their versatility and strength. The Gunite construction process involves spraying a mixture of sand, cement, and water over a steel-reinforced framework, resulting in a solid and long-lasting pool structure. While Gunite pools are known for their resilience, they are not immune to developing cracks over time.

Step 1: Assessing the Type and Severity of Cracks

The first step in dealing with pool cracks is to assess their type and severity. Swimming pool cracks can be categorized into two main types: surface cracks and structural cracks. Surface cracks are minor and often appear on the pool's surface without compromising its structural integrity. On the other hand, structural cracks are more significant and can affect the pool's stability.

Inspect your pool carefully to identify the cracks and determine whether they are superficial or require immediate attention. Minor surface cracks can often be addressed with simple repair techniques, while structural cracks may need more extensive repairs.

Step 2: Seek Professional Assessment

If you are unsure about the severity of the cracks or lack experience in pool maintenance, it's crucial to seek professional assessment. An experienced pool contractor or technician can evaluate the cracks and provide expert advice on the best course of action. They will identify the root causes of the cracks and recommend appropriate repair methods based on their findings.

Step 3: Prompt Repairs for Minor Cracks

For minor surface cracks that do not affect the pool's structural integrity, prompt repairs are essential to prevent further damage and maintain the pool's appearance. Depending on the size and location of the cracks, you can use various DIY repair kits available in the market. Epoxy fillers and patching materials are often used to seal small cracks effectively.

Before starting any repairs, ensure the affected area is clean and dry. Follow the manufacturer's instructions carefully when applying the repair materials. Keep in mind that these repairs are cosmetic and may not address underlying issues that could lead to more significant problems in the future.

Step 4: Addressing Structural Cracks

Structural cracks demand immediate attention as they can compromise the pool's safety and longevity. These cracks may require more complex repair techniques and professional assistance. It is essential to identify the root cause of the structural cracks to prevent recurrence after repairs.

Depending on the severity of the structural cracks, options for repair may include crack injection, shotcrete, or even partial pool renovation to restore the pool's structural integrity.

Step 5: Preventive Measures for the Future

After addressing the existing cracks in your Gunite pool, taking preventive measures can help avoid future cracking issues. Some key preventive steps include:

Regular Maintenance: Implement a regular pool maintenance routine that includes proper cleaning, water balancing, and equipment checks. Regular maintenance helps detect and address potential issues before they escalate.

Monitor Ground Movement: Be aware of any ground movement around the pool area. Tree roots, soil erosion, and ground settling can exert pressure on the pool's structure, leading to cracks.

Proper Water Management: Properly manage the water levels in and around the pool to prevent hydrostatic pressure buildup. Ensure proper drainage and invest in a reliable pool cover to protect the pool during adverse weather conditions.

Address Temperature Changes: If you live in an area with significant temperature fluctuations, consider pool winterization procedures to protect the pool from freeze-thaw cycles.

Quality Construction and Maintenance: Invest in quality construction during pool installation and use premium materials to enhance the pool's durability. Regularly inspect and maintain the pool's structural components to identify any issues early on.


Cracks in swimming pools, including Gunite pools, are a common concern for pool owners. By taking prompt action, seeking professional assessment, and employing appropriate repair techniques, you can effectively deal with cracks and preserve the beauty and integrity of your Gunite pool. Regular maintenance and preventive measures play a crucial role in preventing future cracking issues, ensuring you can continue to enjoy your pool for many years to come without fear of sinking, but rather swimming in delight.
