Professional Pool Crack Repair – Costa Blanca North
At 100% Plumbing, we tackle every fissure—no matter how fine—with industry-leading methods that restore your pool’s strength and prevent water loss. Our technicians begin with a thorough crack assessment, using pressure tests and acoustic sensors to pinpoint both visible and hidden splits. We then prepare the damaged area by grinding and cleaning, before injecting high-performance epoxy or polyurethane resins deep into the substrate. Finally, we finish with a flexible polymer sealant that adapts to temperature changes and resists harsh pool chemicals.

Frequently Asked Questions – Pool Crack Repair
What types of cracks can be repaired?
We repair hairline cracks, structural cracks, and surface fissures in concrete, fiberglass, and vinyl pools. For related waterproofing work, check our general Swimming Pool Repairs page.
How do you fix pool cracks?
Our experts perform leak detection, pressure testing, epoxy or polyurethane injection, and surface refinishing. We also tackle underwater cracks using methods explained on our Underwater Pool Repair page.
Will crack repair work affect my pool finish?
No. After injection, cracks are refinished and re-textured to blend seamlessly with the surrounding surface. Additional upkeep is explained on our Pool Tile Replacement page if aesthetic matching is needed.
How long does crack repair take and is it disruptive?
Small cracks are fixed the same day, while larger or structural repairs may require 1–2 days, including curing time. We recommend avoiding pool use during this period for optimal results.
Is pool crack repair cost-effective compared to full resurfacing?
Yes. Crack injection and refinishing are much more affordable and quicker than full resurfacing, extending the pool’s life by years. According to the National Swimming Pool Foundation (NSPF), targeted structural repairs help preserve pool safety and value.
How long will crack repairs last?
With proper installation and maintenance, repairs can last 5–10 years. We also provide scheduled inspections to prevent recurring issues.
