A little history about Ground Penetrating Radar (GPR)

Concrete X-rays for all types of construction projects began to first emerge in the early 1980’s as it grew to become the technique used in order to reduce risk in Construction Projects. The challenge in the X-ray technology is that the radiation emitted poses a huge risk to humans, specifically when used in a densley populated areas such as office buildings, malls, hotels etc…

Most of the time buildings needed to be evacuated prior to x-ray scan or work had to be done overnight. It is clear that projects took longer due to project delays & disruptions, since scanning with x-rays also took longer, up 5-6 hours a scan.

Fast forward to todays latest state of the art technology Ground Penetrating Radar (GPR) which doesn’t require any work stoppage, and is not dangerous to anyone health, it is safe and secures all environment. A scan can be performed in an industrial area and no personnel need to be evacuated from their office building. As a scan is performed, GPR transmits harmless electromagnetic waves into the ground or any soil or structure and then analyzes the data of the subsurface. Slab thickness can be measured and utilities, reinforcing steel (rebars), post tension cables can all be identified.

It is clear that GPR has brought many advancements to the construction industry. The fact that a scan takes a couple of minutes to a few hours, depending on the scope of the work, is a huge milestone. In light of the advantages of GPR, its cost is minimal in comparison to the cost of a cut pipe, or conduit. Saving time, money reputation and most important of all is the safety it brings to all construction projects, therefore saving the risk.
