What is Underwater Concrete Pile Inspection & Repair?
Submerged concrete piles supporting jetties, wharves and offshore platforms degrade through chloride ingress, freeze-thaw spalling, mechanical impact and reinforcement corrosion. Our service combines an inspection workflow (visual + UTG + crack mapping + half-cell potential) with a repair workflow (chip out + clean + epoxy injection or jacketing + anti-spall coating + cathodic protection).
When do concrete piles need inspection or repair?
- Surface spalling visible above waterline — usually means hidden damage below
- Rust staining on the pile — reinforcement corrosion, demands immediate attention
- Annual integrity inspection — port operator or terminal warranty programme
- After vessel impact — even minor knock can crack concrete cover
- Approaching design life end — extending service life through targeted repair
Our Concrete Pile Workflow
- Visual inspection — full pile surface, HD video, defect mapping
- UT thickness gauging — measuring residual concrete cover above reinforcement
- Crack mapping — width, depth and pattern of all visible cracks
- Half-cell potential — locating actively corroding reinforcement
- Repair design — engineering drawing, materials list, repair priorities
- Repair execution — chip out spalled concrete, clean reinforcement, epoxy / mortar reinstatement, jacketing if required
- Anti-spall coating — chloride-barrier coating to extend life
- Cathodic protection — sacrificial anodes installed if reinforcement corrosion is active

Frequently Asked Questions
Q1. Is concrete pile repair feasible underwater?
Ans: Yes — modern marine epoxy systems (ie. underwater-curing epoxies and inhibited mortars) achieve 28-day strengths comparable to dry-cured. The key is surface preparation, which our divers do with high-pressure water jets.
Q2. How long does pile repair last?
Ans: A properly executed jacket + anti-spall coating + cathodic protection package extends service life by 25+ years on a typical port pile.
Q3. Do you handle the engineering as well?
Ans: Yes — single-source: inspection, engineering, repair, coating and verification. You get one PO and one report.
