Expertise
Five material specialities at the heart of underwater integrity.
MAREX concentrates on the materials that decide the safety and service life of underwater structures. Each speciality combines field inspection, materials science and knowledge of the aquatic environment.
Acrylic viewing panels
Condition assessment of giant acrylic panels and tunnels for underwater viewing.
Hyperbaric silicone sealing
Inspection, leak detection and repair supervision of structural silicone joints.
Concrete & waterproofing
Thermodynamic waterproofing and tank watertightness systems.
Rebar corrosion
Corrosion of carbon steel reinforcement in concrete, potential mapping and diagnosis.
Stainless steel in seawater
Corrosion analysis and prevention for stainless steel exposed to seawater.
Methods
- Underwater visual inspection with photo and video evidence
- Ultrasonic thickness and NDT techniques
- Corrosion potential mapping of reinforcement (half-cell method)
- ROV and aerial drone inspection
- Leak detection on sealing systems
- AI-assisted data analysis and reporting
