Radar Concrete Scanning
Scanning a floor at a hydroelectric power plant with concrete scanning radar.
 

Radar-based concrete scanning is the state of the art in concrete inspection technology, and provides the accurate results that you need when dealing with structures within concrete.

Our concrete scanning system locates structures embedded within concrete slabs prior to drilling, cutting or coring, to a depth of 24 inches or more. A 32" x 32" area of concrete can be inspected and its contents accurately marked in just five minutes. Only single-sided access is required to perform concrete scans (as opposed to X-ray inspection, which needs access to both sides), and thousands of square feet can be inspected in a single day. Faster, safer, and less expensive than traditional X-ray radiography, radar concrete scanning is the best method available for determining what objects lie inside concrete slabs – and exactly where they are.

Scanning a concrete floor at the Portland Jetport - the overlay graphic shows what the concrete scan data looks like.

As an example, the picture at left shows Glen scanning a section of concrete floor at the Portland International Jetport. This particular section of the Jetport is warmed by radiant-floor heat pipes buried within the concrete: it's very comfortable heat, but the heat pipes make it tricky to work in the concrete without hitting anything. When the need arose to cut some cores into the concrete, we came in with our concrete scanner and found a safe place to core that dodged all of the radiant heat pipes - and rebar.

For years, the only way to perform subsurface structure location on concrete was to use X-ray radiography. Trouble is, X-ray concrete inspection requires lengthy preparation, the evacuation of the work site, and a great deal of time to actually shoot, develop and interpret the films. Not only does this limit how much area can be covered in a day, it drives the price up. Using our portable concrete scanning unit, we can quickly survey a large area at any time, with no radiation exposure risks and no need to clear crews from the site. Plus, we can immediately mark right on the concrete where obstructions lie and where the clear paths through the slab are. It's the fastest way we know of to dig safely through concrete.

In a nutshell, our concrete imaging service provides:

A typical rebar strcture, before concrete is poured over it.With this system, we are literally looking through a concrete slab, and we can tell inch-by-inch what's inside. With a typical rebar structure like this in a slab, the accurate data we provide saves time and money: it prolongs drill and coring bit life by avoiding cutting through the steel rebar, and it prevents hitting embedded utilities in the slab.
