Concrete core drilling is the process of making precise circular holes and openings in the concrete structure. Core drilling equipment is used to make the cut in the concrete structure. But before invasive work is performed, it is important to understand what is beneath the concrete surface. That’s where the role of GPR concrete scanning comes into play.

Concrete Scanning with GPR is the process of inspecting the concrete surface using non-destructive ground-penetrating radar. This method is used to detect the materials beneath the concrete surface.

GPR scanning is linked to the concrete core drilling to ensure the safety of the core drilling operations. Find out the role of GPR scanning in core drilling operations.


Locate Rebars

Rebars are the important structural components that resist the load of the structure. Core drilling equipment can create holes from 1 inch to 60 inches in diameter. If you accidentally cut the rebars or cut the rebar at the wrong section, it may result in severe structural damage and sometimes even result in collapse. You can determine the exact location of the rebars with GPR scanning and prevent accidents.

Prevent utility lines damaged

Most of the utility lines run beneath the concrete surface. Now, when some invasive work is required on a concrete structure, it is difficult to figure out where the utility lines are just by looking at the surface. Drilling at the wrong location may end up damaging the utility lines. If you accidentally cut the electric lines, it may result in a power outage, costly repairs, and electrocution of the workers. Similarly, damaging the plumbing lines can result in major water leaks, which are costly to repair and cause inconvenience.

Scanning the concrete structure with GPR can locate the utility lines and provide the information for the drilling staff to make openings at the right location.


Locate voids    

Voids occur in the concrete structure due to a variety of reasons. Making circular openings in the concrete walls, slabs, and columns at the hollow places may put the structure stability at risk. This can put the lives of the workers at risk. Making a thorough inspection with ground-penetrating radar can avert accidents. It can locate the voids, measure the slab thickness, and calculate the spacing of rebars.

These are the primary three ways GPR scanning of concrete is linked with concrete core drilling.

How to perform the concrete scanning?

Concrete scanning is performed using ground-penetrating radar. You can hire ground penetrating radar services in Virginia to perform concrete scanning. The analysis of the GPR images obtained is required to accurately inspect the concrete structure. The accuracy of the results depends on various factors such as ground-penetrating radar, concrete structure, and interpretation of results.

You can hire an experienced team of Concrete Insight GPR scanning professionals for accurate inspection of concrete structures, measure slab thickness, and locate rebars, PT cables, conduits, and voids. We use Structure Scan Pro SIR4000 that can be used to accurately detect metal, plastic, voids, geological features, and more.
