Uncovering the Depths of Concrete Scanning

When it comes to concrete scanning, the usual maximum depth of penetration is around 24 inches or 600 mm. Ground Penetrating Radar (GPR) equipment is only capable of scanning up to 20 inches, but if access to both sides of the slab is available, then thicker concrete can be scanned. GPR is an effective method for determining what lies within concrete structures, as it is non-destructive and emits no harmful radiation. It can also be used to quickly scan large areas without prior setup, and generally penetrate to depths of 18-24 inches.

Concrete scanning can detect rebar, post tension cables, electrical conduits and voids, as well as being used for structural review and measurement of the concrete slab and rebar spacing. It is comparatively cheaper than other methods such as X-ray imaging, and if scanning from opposite sides, it is possible to see through concrete up to 26 inches thick. When it comes to a specific survey area and objectives, SiteScan is the leading provider of subsurface imaging, concrete scanning and utility locating services in California. Our team of highly experienced certified technicians are experts in the latest technology and can be on site within 24 hours of your call.

With GPR there is no need to evacuate a construction site for fear of exposing other workers to radiation, as you would with concrete x-ray scanners. A concrete scan is critical to site safety and can locate and identify objects within the concrete. Xradar-enhanced concrete scanning is a new method of imaging concrete with the accuracy of X-ray and the safety and efficiency of GPR. Concrete less than three months old has a higher moisture content than concrete that has had more time to cure, so it is better to wait before scanning.

In this case we would have to try to scan the concrete from different sides or edges to see what is under the mesh or matting layer.The signal is deflected into the device in different patterns depending on the type of material in the concrete and the depth of the concrete. GPR scanning of concrete is used to find the position or determine the depth of anything embedded within a concrete structure, such as pipes, ducts, reinforcement bars, etc. GPR and X-ray scanning devices are two of the best options among the technologies for non-invasive scanning of concrete structures.When working on a construction site such as a renovation, there are multiple ways to scan concrete structures for safety purposes. Ensure that your workforce remains safe and that your project stays on track by scanning concrete prior to construction.

GPR signals may be inhibited or bounced if the scanned slab has a significant water or moisture content.Concrete scanning is used to inspect concrete slabs or columns prior to drilling or coring in renovation and new construction projects. Before drilling, boring or cutting a concrete structure, a concrete scan helps identify the location and depth of embedded objects with high-resolution ground penetrating radar (GPR).
