Underwater Pile & Pylon Restoration
Restoring the Strength of Marine Infrastructure
Wells Marine provides specialist underwater pile and pylon restoration services for wharves, bridges, marinas, ports, jetties and waterfront infrastructure throughout Sydney, the east coast and inland New South Wales.
Piles and pylons form the structural foundation of many marine assets. Constant exposure to seawater, tidal movement, vessel impacts, marine borers and corrosion can weaken these critical components over time. Without regular inspection and restoration, structural deterioration can compromise safety, increase maintenance costs and shorten the life of valuable infrastructure.
Combining experienced commercial divers, specialist marine construction crews and purpose-built equipment, Wells Marine delivers practical restoration solutions that help extend the service life of marine structures while reducing the need for costly replacement.
Contact Wells Marine to discuss your underwater pile or pylon restoration project.

Underwater Pile Inspections
Understanding the Condition Below the Waterline
Before restoration work begins, our commercial divers carry out detailed underwater inspections to assess the structural condition of each pile or pylon.
Inspections can identify:
- Corrosion
- Concrete spalling
- Cracking
- Exposed reinforcement
- Marine borer damage
- Steel deterioration
- Impact damage
- Scour around foundations
- Structural movement
- Missing protective coatings
Detailed reports supported by underwater photography and HD video help engineers and asset owners determine the most appropriate restoration strategy.
Steel Pile Restoration
Protecting Structural Steel
Steel piles are continually exposed to saltwater, oxygen and marine growth, creating conditions that accelerate corrosion.
Wells Marine provides restoration solutions including:
- Corrosion removal
- Surface preparation
- Steel repairs
- Reinforcement installation
- Protective coating preparation
- Cathodic protection installation
- Structural strengthening
Our goal is to restore the structural integrity of the pile while extending its operational lifespan.
Concrete Pile Repairs
Restoring Structural Performance
Concrete piles can deteriorate through cracking, impact damage, chloride attack and reinforcement corrosion.
Our restoration services include:
- Concrete repairs
- Reinforcement treatment
- Structural patching
- Underwater grouting
- Concrete reinstatement
- Protective wrapping systems
- Structural strengthening
Each repair is completed in accordance with the project’s engineering requirements to provide a durable, long-term solution.
Timber Pile Restoration
Extending the Life of Timber Structures
Timber piles remain common throughout many marinas, jetties and heritage waterfront structures.
Over time, timber can deteriorate due to marine borers, decay and physical damage.
Wells Marine undertakes:
- Structural timber repairs
- Marine borer remediation
- Protective wrapping
- Reinforcement systems
- Partial pile replacement
- Structural strengthening
Where appropriate, restoration can significantly extend the service life of existing timber infrastructure.
Cathodic Protection
Controlling Corrosion
Cathodic protection is one of the most effective methods of slowing corrosion on submerged steel structures.
Our commercial divers install, inspect and maintain cathodic protection systems for:
- Steel piles
- Marine terminals
- Wharves
- Bridges
- Pontoons
- Industrial waterfront facilities
Regular inspections help ensure these systems continue providing effective corrosion protection.
Protective Jackets and Encapsulation
Long-Term Structural Protection
Pile jackets provide an additional barrier between the structure and the surrounding marine environment.
These systems can:
- Reduce corrosion
- Protect repaired sections
- Prevent further deterioration
- Improve structural durability
- Extend asset life
Depending on the application, restoration may include grout-filled jackets, composite systems or engineered encapsulation methods.
Underwater Concrete Restoration
Repairing Marine Concrete Structures
Marine concrete requires specialised repair techniques due to continuous water exposure and restricted access.
Wells Marine provides:
- Underwater concrete placement
- Crack repairs
- Surface restoration
- Structural patching
- Void filling
- Grouting
- Reinforcement protection
These repairs restore structural integrity while helping prevent further deterioration.

Our Restoration Process
Initial Consultation
We review your project objectives, existing reports and operational requirements.
Underwater Inspection
Commercial divers inspect the piles or pylons to identify deterioration, damage and structural defects.
Condition Assessment
Inspection findings are documented to assist engineers and asset owners in selecting the most appropriate restoration method.
Restoration Works
Our experienced marine construction crews complete the required repairs using specialist equipment designed for underwater applications.
Final Inspection
Completed works are inspected to verify quality, structural integrity and compliance with project requirements.
Ongoing Maintenance
Where required, Wells Marine can develop ongoing inspection and maintenance programs to maximise the service life of restored assets.
