Marine Civil Engineering Services
Civil Engineering in Marine Environments
Kaymac is a specialist marine civil engineering contractor delivering complex construction and maintenance projects in challenging coastal and offshore environments. Since 1994, we have provided expert solutions to combat coastal erosion, flooding, and sea level rise, while supporting critical infrastructure, including ports, harbours, railways, and water assets.
Our in-house team of chartered civil engineers, project managers, and skilled operatives combine technical expertise with practical construction knowledge to deliver safe, cost-effective, and sustainable marine engineering solutions. We work collaboratively with clients across government, local authorities, rail, marine, and utilities sectors to achieve high-quality project outcomes.
Our Marine Civil Engineering Capabilities
Bridge Repairs and Structural Strengthening
We specialise in the repair, strengthening, and rehabilitation of masonry and timber bridges, particularly in tidal and coastal environments. Our services include:
- Crack stitching and underpinning
- Timber structure repairs and reinforcement
- Structural rehabilitation in marine conditions
Projects are carefully planned to minimise disruption, often delivered from floating plant such as barges and modular pontoon systems, ensuring efficient access in difficult locations.
Temporary Works and Marine Access Systems
Temporary works are critical to successful marine construction. Kaymac delivers safe and compliant temporary works solutions, including:
- Cofferdams and temporary retaining systems
- Marine access platforms and floating systems
- Bespoke temporary works design and implementation
Our CITB-qualified Temporary Works Coordinators ensure all systems are designed, checked, and executed in accordance with current regulations and best practice.
Embankment and Revetment Stabilisation
We provide coastal and inland stabilisation solutions to protect infrastructure from erosion and failure. Our services include:
- Soil nailing and ground reinforcement
- Installation of geotextile systems
- Rock armour placement and revetment construction
These solutions are designed to address landslips, fluvial erosion, and structural collapse, extending the lifespan of critical assets.
Topographic and Site Surveys
Our team delivers accurate topographic surveys to support marine and civil engineering projects. Using advanced technology, we provide:
- GPS and robotic total station surveys
- 3D site mapping and data capture
- Detailed analysis of terrain and infrastructure
This enables informed decision-making and precise project planning across complex environments.
Structural Inspection, Maintenance and Repair
Kaymac carries out detailed structural inspections and maintenance of marine and civil infrastructure, including:
- Bridges, aqueducts, and culverts
- Ports, harbours, and coastal structures
- Marine assets requiring specialist access
Following inspection, we deliver targeted repair and maintenance solutions to ensure long-term structural integrity and compliance.
Spray Concrete for Marine Structures
We offer advanced sprayed concrete (shotcrete) solutions designed specifically for marine environments. Benefits include:
- Rapid application between tidal windows
- High bond strength and durability
- Enhanced chloride resistance
This method is ideal for the repair and protection of sea walls, groynes, piers, and jetties, extending asset life in harsh coastal conditions.
Confined Space Civil Engineering Operations
Kaymac delivers specialist confined space inspection, maintenance, and repair services in line with HSE Confined Space Regulations 1997. Our capabilities include:
- Surveys and inspections of culverts, tunnels, and outfalls
- Installation and operation within limpet dams and habitats
- Cleaning, de-silting, and structural repairs
- Maintenance of lock gates and caissons
By combining diving expertise with civil engineering capability, we provide safe and effective solutions for complex confined space environments.
