Concrete scanning is a non-destructive method of discovering the secrets of concrete structures. Ground Penetrating Radar (GPR) is the most common and useful tool used to scan concrete, as it is fast and provides instant images. GPR uses pulsed electromagnetic radiation to scan concrete, emitting electromagnetic pulses with a specific centre frequency to scan the underground environment. The waves reflected by the subsurface layers and objects are picked up by the receiving antenna on the surface, capturing the objects and recording the individual traces and scans.
At United Scanning, we use the latest technology, developed by the world's leading GPR manufacturer, to locate and record the details of ducts and services. Our specialist technicians use a range of antennae that enable us to accurately locate rebar, post-tensioning, ducts and voids within and below slabs, as well as detect utilities, subsidence, services, data, stormwater and sewerage to a depth of up to 5m. We also carry out concrete testing. We provide structural engineers, building contractors, forensic experts and concrete specialists with the essential information they need and serve multinational companies, engineering and construction specialists, local and state government agencies, as well as residential and small business customers.
In some cases, X-rays are considered to be more accurate than GPR scanning as there is less scope for interpretation of the results, including visualisation of the condition of rebar and areas of corrosion or other defects. However, GPR can scan large areas in one or more displacement images producing a vertical sectional view of the test area much like a hospital MRI. GPR technology is the best tool for a slab scanning and concrete inspection job. Instead of hammering the concrete to discover that it has been dug in the wrong place, concrete scanning takes all the guesswork out of your job, allowing you to work on any concreted area safely.
We offer a selection of systems for concrete scanning so that you can choose the one that best suits the needs of your project. At United Scanning we provide our clients with fast and accurate information about the structure, strength and composition of their concrete structures. The images and image interpretations are provided in a timely manner and the process of acquiring the information is safe, non-destructive and can be done without significantly disturbing the space being scanned.
