Concrete Scanning

Concrete Scanning

RE&LS offers superior concrete scanning and underground utility locating services to our clients. We specialize in non-destructive scanning of concrete up to 18″ thick to locate post-tension cables, conduit, rebar, and other embedded metallic and nonmetallic materials – all within a 1/4″ accuracy.

Concrete scanning is used to inspect concrete slabs or columns before coring or drilling in renovations and new construction projects. Our concrete scans are completed using Ground Penetrating Radar (GPR) technology for quick and accurate inspections. GPR is both safe and noninvasive; by using transmitted waves and their reflected signals, we can analyze the subsurface to detect embedded objects. A fast and efficient concrete scan can give your project engineers vital information on the concrete depth, objects within the concrete, and any possible air pockets that are undetectable from the surface .

Some applications include.

  • Conduit location
  • Reinforcement location
  • Post tension cable location
  • Slab thickness
  • Duct bank location
  • Wall and ceiling surveys
  • Detection of sub-surface cavities
  • Location and orientation of buried metallic objects
  • Locate steel reinforcement in concrete elements
  • Determine rebar location and spacing
  • Estimate concrete cover thickness
  • Identify major voids and discontinuities in concrete slabs
  • Inspection of tunnel lining

A concrete scan is critical to job site safety and can locate and identify objects within the concrete. This is done to prevent injury, damage, and additional costs during building. Whether you need to core though multiple floors, or need to saw cut a trench in the basement / ground floor level, our team of skilled utility locators can detect and mark-out utilities and structural members embedded in and below concrete walls, floors, and columns. We can even locate sanitary sewer lines under the concrete floor for your future tie-in.


RE&LS uses the StructureScan™ Mini XT for concrete inspection and evaluation. Easily and accurately locate the position and depth of metallic and non-metallic objects in concrete structures, including rebar, conduit, post-tension cables, pan decking, voids and service utilities.

The StructureScan Mini XT is typically used to:

  • Find rebar, post tension, conduits, and non-metallic objects
  • Measure slab thickness and void location
  • Concrete scanning and imaging
  • Condition assessment
  • Structure inspection

The device uses ultrasonic wave technology to penetrate the substrate and has the ability to create files to save scans & to download the information. The hand held digital scanning unit display shows depth & position
