Applications

Application Areas

The 3D subsurface and surface imaging capabilities of Kerberos™ and Lynx are useful for a wide range of applications, including:

Pavements

  • Scanning roads, airport pavements, bridge deck wearing surfaces and bridge approaches,  concrete turnouts etc to determine ‘as-constructed’ details; locating changes of construction; mapping and identifying prior remediation & repairs.
  • Detecting subsurface voids, pavement defects, and  subgrade obstructions such as boulders or old buried infrastructure.
  • Mapping extents and distinguishing between areas of homogeneous construction from those with varying depth and configuration.
  • Optimising the number and value of cores and trenches by targeting them to the most representative locations.
  • Detecting areas of moisture ingress.
  • Capturing a snapshot of surface imagery across large or small sites (roads, airport pavements, port facilities, concrete hardstand areas, etc.) for documentation, monitoring or evidentiary purposes

Subsurface Utilities / PUP

  • Locating, mapping and estimating the depth of subsurface utilities
  • Detecting and mapping the location of buried pits and protection slabs
  • Comparing features in surface imagery (e.g. access hatches) and subsurface 3D NM-GPR (e.g. pipes, protection slabs, pits) over vast areas to achieve a more holistic and complete understanding of site conditions

Bridges

  • Mapping the depth of asphalt Deck Wearing Surface (DWS) to plan remedial works and rebar cover depth
  • Identify underlying causes of bridge approach failures
  • Capture surface images of existing condition, for monitoring or evidentiary purposes

Law enforcement

  • Identifying the presence and precise location of buried objects or location of disturbed earth

Environmental

  • Mapping the pattern of tree roots, determining near-surface geology, measuring the depth of capping layers, etc.

Archeology

    • Locating and mapping buried structures, grave plots
