Swimming pools are built to handle pressure, water weight, and weather changes. However, even the strongest pools can develop cracks over time. While some cracks are cosmetic, others may signal deeper structural concerns. Knowing what causes cracks and understanding how to fix pool cracks early can prevent serious damage and expensive repairs.
If you’re searching for pool crack repair near me, it’s important to first understand the type of crack and what it means for your pool’s safety and durability.
Main Causes of Pool Cracks
Several factors contribute to cracking in pools and surrounding decks.
Soil Movement and Settling
The ground beneath your pool can shift due to erosion, heavy rainfall, or natural settling. In areas like Miami, fluctuating moisture levels in the soil put pressure on the pool shell, leading to structural stress.
Temperature Changes
Concrete expands in heat and contracts when temperatures drop. Repeated expansion and contraction cycles weaken the surface and may cause visible cracking in both the pool and surrounding deck.
Poor Construction Practices
Improper reinforcement, low-quality materials, or rushed construction can create weak points in the pool shell. Over time, those weaknesses show up as cracks.
Aging Materials
Like any concrete structure, pools naturally age. Hairline cracks may appear as materials cure and settle over the years.
Improper Water Chemistry
Unbalanced pool water can deteriorate plaster finishes. High acidity or chemical imbalance weakens the surface, increasing the risk of cracking.
Types of Pool Cracks
Understanding the types of pool cracks helps determine whether the issue is cosmetic or structural.
- Surface Cracks- These are small, hairline cracks that typically appear in plaster finishes. They are usually shallow and affect only the top layer. While often cosmetic, they can worsen if ignored.
- Structural Cracks- Structural cracks extend deeper into the concrete shell. These cracks are more serious and may result in water loss or shifting. Professional pool crack repair is necessary for these cases.
- Pool Deck Cracks- Cracks can also develop around the pool deck. Sun exposure, heavy foot traffic, and ground movement are common causes. Proper pool deck crack repair, especially concrete pool deck crack repair, improves safety and prevents tripping hazards.
| Crack Type | Depth | Risk Level | Recommended Action |
|---|---|---|---|
| Hairline Surface | Shallow | Low | Patch and seal |
| Structural | Deep | High | Professional repair |
| Deck Cracks | Surface | Medium | Concrete repair |
How to Fix Pool Cracks
The method depends on the crack’s depth and severity.
Surface Crack Repair
Minor cracks can often be repaired by:
- Draining water below the crack level
- Cleaning debris thoroughly
- Applying epoxy filler or plaster patch
- Smoothing and sealing the area
This type of repair prevents moisture intrusion and extends surface life.
Structural Crack Repair
Structural cracks require expert attention. Professionals typically:
- Perform pressure testing
- Use epoxy or polyurethane injection
- Reinforce weakened areas if necessary
Prompt pool crack repair protects the structural integrity of the pool and prevents long-term damage.

Concrete pools are durable but require maintenance. Follow these repair tips:
- Address cracks as soon as they appear
- Use high-quality epoxy or polyurethane materials
- Ensure proper curing time
- Monitor for recurring cracks
Routine inspections combined with consistent Weekly Maintenance reduce the risk of serious damage.
Important Tip: Pool Crack Prevention Tips
Prevention saves both time and money. Consider these steps:
- Maintain balanced water chemistry
- Avoid completely draining the pool unless necessary
- Inspect deck joints annually
- Monitor water levels for unusual drops
- Schedule regular professional inspections
Taking these precautions reduces the need for major structural repairs.
How to Tell If a Pool Crack Is Structural
