Experienced Technical Team

One of the most common GPR scanning applications is Concrete Scanning. Terraprobe has completed thousands of concrete scanning projects and many of our technicians have completed thousands of scanning locations themselves.

In fact, we have accumulated so much experience in concrete scanning that we are now conducting GPR Concrete Scanning courses around the world.

TerraProbe stands apart through our extensive field experience and technical proficiency. Our professionals have accumulated over 50 cumulative years of hands-on experience in concrete scanning and GPR analysis. This depth of expertise allows us to quickly interpret data and provide actionable insights, helping you navigate even the most complex projects with confidence. Our team's experience extends beyond just scanning; we provide comprehensive support, from initial consultation to final analysis, ensuring your project remains on track and within regulatory compliance.

What our Technicians can do for you!

Locate rebar

Map rebar spacing and depth in concrete, including slab-on- grade with multiple layers of rebar/other embedded elements.

Locate conduits

Map plastic and metal conduits with precision to avoid damage when drilling, cutting, or coring.

Locate post-tension cables

Map post-tension cables with precision to avoid damage when drilling, cutting, or coring through post-tensioned concrete.

Locate voids

Under concrete structures, behind walls, in tunnels, etc.

Measure slab thickness

Determine and record the slab thickness for both slab-on-grade and suspended slabs, determine rebar depth to measure concrete cover in slabs, beams, and columns

CAN GROUND PENETRATING RADAR SCAN CONCRETE SLAB-ON-GRADE?

Yes it can! Because GPR only needs access to one side of a concrete slab or structure to scan the material for anomalies, it can evaluate slab-on-grade.

CAN GROUND PENETRATING RADAR IDENTIFY THE DIFFERENCE BETWEEN REBAR, POST TENSION CABLES, ELECTRICAL CONDUITS AND OTHER EMBEDDED MATERIALS?

While the GPR itself can only identify anomalies, our expertly trained GPR technicians can interpret the provided data and let you know what it is the GPR has found and where it's located. Our field markings and reports then help you to understand what we've located so you can make an educated decision on where to drill, core or cut.

HOW ACCURATE IS GROUND PENETRATING RADAR WITH MARKING ANOMALIES IN CONCRETE?

Concrete scanning in the average slab is very accurate. In general, the resolution and accuracy of the radar diminishes as the target depth increases. For concrete slabs up to 12” we are able to locate targets to within about 1 cm horizontally.

Our work flow is designed to take into account both the radar accuracy and the type of target. First, we "calibrate” the radar (hyperbola matching) to increase radar accuracy for each site. We also use safety margins for our markings that take into account the critical nature of the target. ie. Wider for post tension cables and narrower for rebar.

ARE THERE ANY HEALTH RISKS ASSOCIATED WITH GROUND PENETRATING RADAR?

No. GPR scanners use radio waves, and typically produce a smaller power output than most cell phones. It is also non-destructive.

HOW LONG DOES IT TAKE TO SCAN AN AREA FOR CORE DRILLING?

Our rule of thumb for scanning time for clearing for core drilling is 30 minutes for a 3’x3’ area. This is based on scanning from one side only and will vary depending on the quantity and types of targets found during the scan.
