Rebar Scan

Rebar Scan

Rebar Scan is a test to determine the condition of reinforcement inside concrete elements without breaking or chipping the concrete. Using a rebar detector (rebar scanner), our team can read directly on the instrument's screen: rebar position, rebar spacing (center-to-center), estimated rebar size or diameter, and concrete cover thickness.

This test is important because the number, size, and position of reinforcing bars determine the strength of structural elements. Insufficient concrete cover makes reinforcement more vulnerable to corrosion, while reinforcement that does not match the drawings can reduce structural capacity.

Rebar Scan is especially useful when as-built drawings are unavailable, when a mismatch between drawings and site conditions is suspected, or before coring and drilling work to avoid hitting reinforcement.

Rebar Scan

Scope of Work & Work Stages

  1. Test Point SelectionTogether with you, we determine which structural elements will be scanned (columns, beams, slabs, or walls) based on visual inspection results and analysis needs.
  2. Surface PreparationThe concrete surface is cleaned and the scanning area is marked with a grid.
  3. Equipment CalibrationThe rebar detector is prepared and calibrated before use.
  4. Rebar ScanningThe instrument is moved across the concrete surface to detect rebar position, rebar spacing, estimated diameter, and concrete cover thickness.
  5. Recording & DocumentationReadings are recorded for each test point, complete with photos and location markings.
  6. Analysis & ReportingThe data is compared against design drawings or applicable requirements, then compiled into a report.
