Capabilities
Installation of scour protection
Propeller wash and current strip material from the bed in front of quays, piers and gates. We survey the affected area, place protection to the design profile and confirm coverage afterwards.
Applications
- Scour repair at quay toes
- Bed protection around bridge piers
- Protection at lock approaches
- Placement of concrete mattresses and geotextile
Structures
- Quay toes
- Bridge piers
- Lock approaches
- Pipeline and cable crossings
Method
Pre-placement survey establishes the existing bed profile. Material is placed from a pontoon or crane under diver or ROV guidance, and a post-placement survey confirms level and coverage against the specification.
Equipment
- Survey and sounding equipment
- Grab and crane placement
- Concrete mattresses and geotextile
- Diver-held positioning aids
