Capabilities
Renovation of quay walls
Quay walls deteriorate where they cannot be seen. We survey the submerged section, quantify the damage and carry out repairs so the structure can continue to carry its design load without taking the berth out of service longer than necessary.
Applications
- Underwater concrete repair
- Sheet pile thickness measurement
- Anode and cathodic protection work
- Grouting behind wall panels
- Void and scour detection at the toe
Structures
- Concrete quay walls
- Steel sheet pile walls
- Combi-walls
- Relieving platforms
- Fender and bollard fixings
Method
We start with a graded inspection: visual and tactile survey, thickness readings and photo or video capture per section. Repairs follow the agreed specification — cleaning, reinforcement treatment, formwork and underwater concrete or grout — and are verified after curing.
Equipment
- High-pressure water jetting
- Ultrasonic thickness gauges
- Underwater formwork and grout pumps
- Video inspection systems
Safety
- Exclusion zone around the berth
- Coordination with vessel and crane movements
- Control of jetting reaction forces
- Confined-space assessment behind panels
Frequently asked
- Can the berth stay operational?
- Often partially. We phase the work per section and agree movement windows with the terminal so only part of the quay is closed at a time.
