Concrete scanning, including GPR scanning (ground penetrating), is increasingly being used for various situations like subsurface utility engineering, locating private utility, utility location with existing concrete, preconstruction with utility mapping, and safety hazard recognition.
GPR scanning helps in locating embedded objects within the concrete slabs like radar or other reinforcing steel members, gas pipes, water lines, leak detection and many more.
X-ray scanning, also known as concrete scanning, is a non-destructive testing technique that is often used to identify cracks and other structural defects in concrete structures. To scan a concrete structure, an engineer will use a device called a concrete scanner which emits an x-ray beam through the surface of the structure. This beam reflects off the internal surface of the concrete structure and back to the concrete scanner.
Why is Concrete Scanning Important?
GPR scanning is a major element to the safety of the workers and the success for both new as well as old constructions, utility placement, underground utility repair and many more. GPR scanning helps to detect embedded electrical cables, conduits which can be potential hazards if not detected. By cutting or damaging these objects will lead to the reduction of the strength of the concrete, expensive damage to the utilities and cause huge damage to the health and safety of the workers as well as the public in general.
With proper concrete scanning, your leadership team can get the exact data, thereby allowing them to make a CCTV pipe inspection, invasive testing, remediation and repairs like drilling operations and vacuum evacuation.
If your construction team is working in an existing concrete with various structures as well as utility elements, you will definitely require concrete scanning on the building site. Any type of utility engineering video pipe inspection requires a thorough GPR scanning.
Advantages of Concrete Scanning
Concrete scanning is a non-destructive testing technique that uses electromagnetic waves to analyze and diagnose the condition of the concrete. The electromagnetic waves are sent into the concrete with high-frequency pulses.
If these pulses encounter an electrical impedance difference between the different layers of the concrete, reflections will be generated and those reflections will tell what has been happening to the concrete since it was laid. In this way, it can detect damage, water content, curing, and anything else that has happened to the concrete.
1. Measurement of concrete thickness
Concrete scanning is a process in which a concrete surface is scanned with a laser and the thickness of the concrete layer is measured. This type of scanning can be used for many purposes, including identifying rebar or making sure that the concrete slab is at the correct thickness
Ground-penetrating radar is a non-invasive imaging technique used to identify the subsurface structures of the Earth. It uses electromagnetic waves to detect and map the geometric features of rock layers and objects on the surface and beneath. This data can be used to find the location of archaeological sites, construction challenges such as voids and as, and to measure the depth of buried pipes and cables.
2. Checking for voids and cracks
The advantage of concrete scanning is checking for voids and cracks. Over time, if a crack is not repaired, the steel reinforcing bar within the concrete will become exposed, which can lead to structural damage. This could lead to slab fissures, spalling, and softening or efflorescence of the concrete surface.
It’s called concrete scanning and it’s an innovative method to detect structural defects in concrete buildings, bridges, roadways, parking garages, dams, and other concrete structures. The technology is used by engineers, architects, engineers, construction companies, and other building professionals who want to save time and money when constructing new or rehabilitating existing structures.
3. Ability to monitor changes in the concrete over time
A concrete scan includes the detection of air and water leakage, as well as temperature variations. The detection of air and water leakage is important to monitor because it can lead to problems like soil movement and cracks in the foundation. Monitoring temperature variations can help engineers detect if there are any changes in thermal performance caused by chemical reactions that have occurred.
How do you scan concrete?
Concrete scanning is a non-destructive inspection, scanning and mapping of a concrete structure. The technology is typically used to check for cracks, corrosion, and damage. Companies that offer concrete scanning equipment can either use the existing grid system for a building or install special sensors. The sensors will emit acoustic pulses into the concrete, which will then bounce back. The scans are captured as images and the data from the scan will be saved on a computer.
The data can then be reviewed and analyzed. It is one of the more expensive forms of concrete scanning, typically costing $500 – $2,000 per scan depending on the needs of the client. You can ask your local concrete scanning experts for a copy of their scanning pricelist.
