Concrete Scanning With The Help Of Ground-Penetrating Radar

Concrete scanning is usually done using rebar scanners whose operation is based on ground-penetrating radar (GPR). It proves vital in locating post tension cables located beneath the surface before drilling can be done. Contractors are thus able to carry out various tasks when installing sewerage lines, plumbing and electrical installations among other activities. The work can be carried out quickly and more effectively with the help of ground-penetrating radar technology.


Scanning concrete isn’t complicated at all; the area where drilling is meant to take place on the structure is first identified. A preliminary grid scan is then performed to identify where various items are located. Having done this, the drilling locations can then be mapped away from the area where the installations are.

With this technique, there’s little need for patch-work and repairs afterwards. Contractors can also be precise as they won’t have to move away from holes they’ve already drilled because various installations were encountered. Due to the non-invasive nature, the structural integrity of surrounding structures is safeguarded.


With traditional drilling techniques, activity in the surrounding area has to be minimized. As such, essential services like shopping malls and the like are kept shut so that the drilling work continues. For such interruptions to be avoided, ground-penetrating radar offers the best solution because it prevents damage to all embedded utilities.

Reduced Risk

GPR also reduces hazards encountered in such projects, along with unnecessary delays. This especially applies if electrical conduits are embedded in the concrete structures. Perhaps the best part of this technique is that if handled correctly with the right equipment, expert concrete scanning is very accurate.

Detecting Empty Spaces

The technology also comes in handy when there’s need to detect empty spaces beneath surfaces. Such spaces tend to be left after pouring concrete over a large surface. By locating them, proper maintenance can be done in order to avoid accidents in future.

The basic goal of using GPR remains to accurately point out the location of cables and embedded installations in walls and floors. Drilling patterns can then be mapped out accurately to move away from these points. Generally, prevention would be more preferable to encountering various hazards which could create damage and even result in compensation.

A number of different GPR scanners are offered by various manufacturers. It’s vital to know how accurate each scanner is before buying in order to purchase equipment that provides the best results. Some devices are even equipped with X-ray technology. Though expensive, such scanners are highly accurate, thus cost effective. Though one doesn’t need to be a civil engineering specialist to use the technology, some solid training would be necessary for good results.
