Gunite Pool Repair: Common Issues and Solutions

Gunite Pool Repair Solutions

Gunite pools are celebrated for their durability, aesthetic appeal, and versatility in design. However, like any feature that adds value and enjoyment to your home, they require regular maintenance and occasional repairs to remain in top condition. At Harpeth Valley Hardscape, we specialize in diagnosing and resolving the most common issues associated with gunite pools. Here’s an in-depth guide to understanding these problems and the best approaches to address them.

1. Surface Cracks

Issue:
Surface cracks, also known as check cracks, are minor fissures that develop on the pool’s plaster surface. Natural settling, temperature fluctuations, or the long-term wear of the material typically cause these. While they are generally cosmetic, they can detract from the pool’s appearance if left untreated.

Solutions:

• Patching: Use specialized compounds designed for filling minor cracks. These materials adhere well to gunite and seal the cracks effectively.
• Resurfacing: If the cracks are widespread or recurring, resurfacing the pool may be necessary. Resurfacing involves applying a new plaster layer over the gunite, restoring the surface’s appearance and durability.

2. Structural Cracks

Issue:
Unlike surface cracks, structural cracks penetrate deeper into the pool shell and can compromise its integrity. These cracks can lead to significant water loss, affecting the pool’s usability and causing long-term damage if not repaired promptly.

Solutions:

• Professional Inspection: Structural cracks should always be assessed by an expert to determine the root cause and extent of the damage.
• Repair Techniques: Depending on the severity, repairs may involve injecting hydraulic cement or epoxy into the crack. For severe cases, structural reinforcement, such as adding rebar and additional concrete, might be required before resurfacing the pool.

3. Discoloration

Issue:
Over time, gunite pools can develop discoloration due to minerals in the water, improper chemical balancing, algae growth, or dirt accumulation. This discoloration can make the pool look aged and uninviting.

Solutions:

• Acid Washing: This involves draining the pool and applying a diluted acid solution to remove stains and restore the plaster’s original color. Acid washing is a cost-effective way to refresh the surface.
• Routine Maintenance: Prevent discoloration by maintaining proper water chemistry, performing regular cleaning, and using algaecides or shock treatments to keep the pool clear of contaminants.

4. Tile Problems

Issue:
The tiles around a pool’s waterline are not just decorative—they protect the underlying structure from water intrusion. Over time, tiles can crack, loosen, or fall off due to impact, age, or erosion of the adhesive grout.

Solutions:

• Tile Replacement: Replace broken or missing tiles with matching replacements. If a match isn’t available, consider retiling a larger section for a uniform look.
• Regrouting: Regrouting secures loose tiles and prevents further deterioration. Using water-resistant grout ensures longevity.

5. Plumbing Leaks

Issue:
Plumbing leaks are a common issue in gunite pools, often occurring in the piping system, fittings, or even the pool shell itself. These leaks not only waste water but can also lead to structural issues if the surrounding soil becomes saturated.

Solutions:

• Leak Detection: Conduct professional pressure testing to locate leaks in the pool’s plumbing or structure.
• Repairs: Depending on the location, repairs may involve patching cracks in the shell with hydraulic cement, replacing damaged pipes, or sealing leaks with commercial-grade waterproofing products.

6. Spalling or Scaling

Issue:
Spalling occurs when the surface layer of the pool plaster flakes off, often due to poor water chemistry or improper application during installation. Scaling, on the other hand, results from mineral buildup, leaving a rough and unattractive surface.

Solutions:

• Descaling: Use a descaling solution or pumice stone to remove mineral deposits from the pool surface.
• Plaster Refinishing: In cases of extensive spalling, refinishing the pool plaster restores the surface and prevents further damage.

7. Equipment Failures

Issue:
Faulty pool equipment, such as pumps, filters, or heaters, can affect the pool’s overall performance and water quality.

Solutions:

• Regular Maintenance: Schedule routine inspections and servicing for all pool equipment to identify issues early.
• Upgrades: Consider upgrading outdated equipment to modern, energy-efficient models for better reliability and lower operational costs.

Proactive Maintenance Tips for Gunite Pools

To minimize issues and extend the life of your gunite pool, consider these proactive maintenance strategies:

• Balanced Water Chemistry: Regularly test and adjust pH, alkalinity, and calcium hardness levels to prevent damage to the pool surface.
• Routine Cleaning: Vacuum the pool, brush the walls, and skim the surface weekly to remove debris.
• Professional Inspections: Schedule annual inspections by professionals to identify and address potential problems before they worsen.
