Concrete Radar Concrete Scanning Concrete Inspection Concrete x-ray

concrete inspection and scanning

CRLS uses equipment developed by the world’s leading ground and cement penetrating radar manufacturer to locate and trace almost anything within concrete slabs and walls.

Our technicians have a range of antennas on hand, including the high definition 2600 MHz antenna, which was developed specifically for situations involving closely spaced reinforcement, conduit or small voids within concrete.

We can:

  • Locate reinforcement and pre-tensioned tendons in walls and floors.
  • Locate conduit, PVC pipes and voids within concrete walls and slabs up to one metre in depth.
  • Detect concrete inconsistencies such as voids, cracks, honeycombing and others
  • Locate targets directly under slabs or behind walls.
  • Verify slab thickness.
  • Verify areas safe for cutting and core holes.
  • Precisely locate penetration exit points to avoid thickenings and beams.
  • Measure concrete cover and reinforcement size.
  • Offer a service that is cheaper, safer and quicker than x-ray.
  • Provide all customers with reports as a value added service when required.

Benefits of RADAR over concrete or cement x-ray

X-ray operators need access to both sides of the structure as the transmitter, or source, and the receiver needs to be opposed to each other.

Radar only needs access to one side of the structure being tested because RADAR has the transmitter and receiver in one unit and relies on the reflection of radio waves to produce a meaningful image.

X-ray is damaging to the human body so exclusion zones around the area being tested are necessary meaning part or all of the site will need to be evacuated.

The energy emitted from our Radar units is many times lower than a mobile phone. This means that there is no need for a site to be evacuated or there is any risk of harmful exposure.

X-ray can only produce one image on each exposure meaning that large areas are very time consuming and costly to investigate as the transmitter and receiver need to be constantly moved.

Radar can scan large areas in one or more scrolling images producing a vertical sectional view of the test area much like a MRI from the hospital. These images can be placed together to form a virtual 3D model.
