Underwater Bridge Inspections Backed by Real Experience
Our underwater bridge inspections are carried out by ADAS Certified commercial divers with backgrounds in both structural inspection and marine construction. These aren’t surface-level checks. We provide detailed inspections with high-resolution visuals, condition assessments, and actionable reports.
From tidal estuaries to deepwater river crossings, we assess everything from piles and pile caps to caissons, abutments, and scour zones. You get real insight into the health of your asset, not just a checklist.

Bridges, Jetties, and Wharves: Repairing Marine Piles
Corrosion and cracking are common in marine piles, especially in tidal and splash zones. Our marine pile repair service extends the lifespan of bridge foundations by addressing deterioration
before it becomes a major structural issue.
We offer:
- Composite pile jackets (FRP, HDPE, and steel)
- Crack injection and grout repairs
- Cathodic protection systems (including anode testing and replacement)
- Core sampling for condition analysis
- Encapsulation using proven tape systems
For assets with active deterioration or spalling, pile repair can prevent full replacement, saving significant time and cost.

Whether it’s a scheduled shutdown or an unexpected failure, we offer responsive, certified underwater bridge inspection and repair services. From stabilising compromised piles to supporting barge access for major replacements, we provide reliable results fast.
We also support marine salvage operations, where bridge components or vessels may have collided, sunk, or caused structural disruption. Our team works closely with engineers and local authorities to manage risk, visibility, safety, and documentation.

FAQs – Underwater Bridge Inspectors
How often should bridge piles be inspected?
Bridge piles should be inspected at least every five years under standard guidelines, or more frequently for structures in high-flow or saltwater environments. Regular underwater bridge inspection helps catch corrosion, scour, and damage early. If your bridge supports critical infrastructure or heavy loads, we recommend more frequent reviews to ensure safety and compliance.
What certifications do your underwater bridge inspectors have?
All our underwater bridge inspectors are ADAS Certified commercial divers with additional qualifications in structural inspection, confined space entry, and use of NDT tools like ultrasonic thickness gauges. We also provide certified underwater bridge inspection reports that meet Transport Main Roads (TMR), RMS, and council requirements.
What types of pile protection systems do you recommend?
Do you provide underwater bridge repair services outside Queensland?
What is pile encapsulation and when is it needed?
