Introduction

Underwater pool cracks are a common issue that can cause significant problems if left unaddressed. Whether caused by structural stress, shifting soil, or improper maintenance, these cracks can lead to water loss, equipment strain, and costly repairs.

At Superior Pool Service, we specialize in diagnosing and repairing underwater pool cracks, ensuring your pool remains safe, functional, and visually appealing.

What Causes Underwater Pool Cracks?

Several factors can lead to cracks forming beneath the waterline:

1. Structural Stress

✔ Concrete or gunite pools experience stress over time due to water pressure, soil movement, and temperature changes.

2. Improper Installation

✔ Poor workmanship or the use of substandard materials during construction increases the risk of cracks.

3. Shifting Soil

✔ Soil expansion, erosion, or settlement can place uneven pressure on the pool structure, causing cracks to form.

4. Freeze-Thaw Cycles

✔ In colder climates, water that seeps into small cracks can freeze and expand, worsening the damage.

5. Chemical Imbalances

✔ Unbalanced pH, alkalinity, or chlorine levels can corrode the pool surface, leading to cracks.

Types of Underwater Pool Cracks

Not all cracks are the same. Understanding the type of crack helps determine the appropriate repair method.

1. Surface Cracks (Crazing)

✔ Small, hairline cracks that affect only the plaster or top layer of the pool surface.
✔ Typically cosmetic but can worsen over time.

2. Structural Cracks

✔ Larger, deeper cracks that run through the concrete or gunite shell of the pool.
✔ Can cause significant water loss and structural instability.

3. Hydrodynamic Cracks

✔ Result from pressure imbalances caused by water movement or improper drainage.

How to Identify a Pool Crack

Signs of an underwater pool crack include:

✔ Unexplained Water Loss: Persistent drops in water levels even after evaporation is accounted for.
✔ Wet Areas Around the Pool: Indicating potential leaks.
✔ Stains or Discoloration: Cracks often collect debris or algae, causing visible stains.
✔ Visible Cracks: Clearly seen through the waterline or along pool surfaces.
✔ Increased Water Bills: Higher costs due to water refilling from leaks.

If you notice any of these signs, professional inspection is recommended.

Methods for Repairing Underwater Pool Cracks

There are several options for repairing cracks, depending on their size and severity:

1. Epoxy Injections

✔ Use: For filling structural cracks.
✔ Process: High-strength epoxy is injected into the crack to seal it and restore integrity.

2. Hydraulic Cement

✔ Use: For patching smaller cracks.
✔ Process: Hydraulic cement is applied underwater to seal the crack and prevent water loss.

3. Underwater Pool Plaster Repair

✔ Use: For resurfacing areas with crazing or surface cracks.
✔ Process: Specialized plaster is applied and smoothed for a seamless finish.

4. Fiberglass Reinforcement

✔ Use: For extensive structural cracks in fiberglass pools.
✔ Process: Fiberglass patches are applied over the damaged area to reinforce the structure.

5. Full Resurfacing

✔ Use: For pools with widespread cracking or aging finishes.
✔ Process: The pool surface is stripped and refinished with new plaster, pebble, or tile.

Superior Pool Service uses advanced tools and techniques to ensure long-lasting repairs.

Preventing Underwater Pool Cracks

Taking proactive steps can minimize the risk of cracks forming:

✔ Maintain Balanced Water Chemistry: Prevent corrosion by monitoring pH, alkalinity, and chlorine levels.
✔ Schedule Regular Inspections: Identify and address potential issues early.
✔ Ensure Proper Drainage: Prevent hydrodynamic pressure by managing water flow around the pool.
