Fiberglass Pool Repair – Overcoming Tidal Pressure Challenges
At Robinson Restorations Inc., we specialize in fiberglass pool restoration and pool repair along the Outer Banks, where unique coastal conditions can create serious structural challenges. Our most recent project in Kill Devil Hills, NC, involved restoring a fiberglass pool that cracked due to tidal water pressure beneath it.
The Challenge: Coastal Water Pressure & Pool Damage
This particular fiberglass pool was installed at sea level, making it highly susceptible to hydraulic pressure changes caused by ocean tides. When the pool was drained, the natural groundwater—pushed by tidal fluctuations—created immense pressure underneath the shell, causing it to crack and shift.
As a result, water continuously seeped into the work area, making it necessary to constantly pump water out while we performed the repairs. This is a common issue for pools in low-lying coastal areas, where improper drainage planning can lead to serious structural failures.
Our Fiberglass Pool Repair Process:
To ensure a long-lasting repair, we followed a meticulous process:
- Continuous Water Management: Using pumps, we actively removed intruding groundwater throughout the repair process to keep the work area dry.
- Precision Cutting & Reshaping: We cut and reshaped the cracked fiberglass to prepare it for reinforcement.
- Structural Reinforcement: High-quality marine-grade fiberglass and resin were used to restore the pool’s integrity.
- Sealing & Finishing: After structural repairs, we refinished the pool’s surface, ensuring a smooth, watertight, and durable finish.
Preventing Future Pool Damage in Coastal Areas
If you have a fiberglass pool near the coast, here are some key tips to prevent structural damage:
✅ Never drain the pool without professional guidance—lowering water levels can create dangerous pressure imbalances.
✅ Install a hydrostatic relief valve—this allows groundwater to enter the pool rather than pushing up on the shell.
✅ Ensure proper drainage planning—sump wells and pumps can help control underground water pressure.
