Is it possible to assess underground utilities and structures without digging the ground? Yes, GPR concrete scanning has made it possible to locate underground utilities without causing any damage to the ground surface.
Concrete scanning is a non-destructive concrete assessment technique that uses ground penetrating radar, or GPR, to identify embedded utilities and analyze the integrity of the structure before cutting, coring, or drilling the concrete. GPR scanning is more reliable, less invasive, and safer than X-rays for assessing concrete walls, slabs, and columns since it uses reflected radio waves.
Why is GPR concrete scanning important?
GPR concrete scanning is important for the safety of workers, underground utility repair, traffic management and for the success of both new and existing concrete construction.
GPR scans find hidden dangers, including wires, rebar, and electrical conduits that might otherwise go undetected. Cutting or damaging these elements could reduce the performance and strength of the concrete, resulting in expensive utility damage or posing a risk to the health and safety of workers and the general public.
Few Important Questions to know about GPR Concrete Scanning
When do you need to scan concrete?
Concrete must be scanned right before any destructive work is performed. This can include procedures like coring, drilling, cutting, and others that weaken the strength of the concrete.
Why is concrete scanning required?
When concrete is scanned, all significant internal concrete components are identified. This helps to prevent destructive work from being done to materials like conduits or rebar.
How does concrete scanning with GPR work?
Ground-penetrating radar scans the concrete building using electromagnetic waves. A transmitter antenna sends the electromagnetic signals, which are subsequently reflected back by the objects and picked up by a receiving antenna. These reflected signals are used to construct the graph. Finally, a GPR engineer interprets the graph to establish the utility's location and type.
Does GPR directly tell about the type of utility?
No, a GPR cannot identify the type of utility. Instead, a GPR engineer uses experience and knowledge to interpret the type of utility and its position within the structure.
What can GPR detect?
PVC, air spaces, steel, and plastic can all be found with advanced GPR equipment. However, GPR scanning might cost anywhere between $500 and $1000.
What are the factors that affect the accuracy of the GPR scanning?
The accuracy of the GPR scanning depends upon various factors, such as the capability of the GPR, the presence of obstacles in concrete structures, and the interpretation skills of the GPR engineer.
