UK Diving Services Deliver Specialist Bridge Scour & Underwater Structural Condition Surveys Across the UK
December 2025
UK Diving Services Ltd (UKDS) continues to support local authorities, engineering consultancies, and infrastructure owners across the UK with specialist bridge scour inspections and underwater structural condition surveys in some of the country’s most challenging marine and inland waterway environments.
As a leading UK commercial diving and underwater investigation contractor, UKDS provides diver-led inspections supported by advanced sonar and hydrographic technology, ensuring accurate, data-rich assessments of submerged assets.
Specialist Bridge Scour Surveys & Underwater Inspections
Scour remains one of the most significant risks to bridge safety and serviceability. UKDS routinely undertakes CS 469 Level 1 scour data collection surveys, identifying bridges that may require more detailed Level 2 scour assessments.
Our scour inspections include:
-
Riverbed and seabed profiling
-
Identification of scour holes, undercutting, and undermining
-
Bathymetric and sonar-backed surveys in zero-visibility water
-
Structural probing of foundations, piers, and abutments
These surveys provide asset owners with a clear understanding of risk and inform targeted maintenance or remedial works.
Underwater Structural Condition Surveys
In addition to scour assessments, UKDS delivers comprehensive underwater structural condition surveys of bridges, culverts, river walls, piers, jetties, and marine structures.
Our commercial diver inspection teams assess:
-
Concrete, steel, masonry, and timber structures

Corrosion, section loss, cracking, and impact damage
-
Previous scour protection and repair measures
-
Submerged structural elements in tidal and non-tidal waterways
All inspections are supported by high-resolution underwater imagery, video, and sonar data, ensuring robust and defensible reporting.

To improve safety and data quality, UKDS utilises cutting-edge underwater survey systems including:
-
Norbit Winghead multibeam sonar
-
BlueView 2D and 3D imaging sonar
