Ground Penetrating Radar Services- How They Are Used for Concrete?
Faster than X-rays, ground penetrating radar for concrete requires access to only one side of the concrete. It’s an ideal solution for slab-on-grade in which the concrete is poured directly onto the ground.
GPR scanning for concrete works by emitting a pulse into the ground and recording the reflections resulting from subsurface objects. It also detects variations in the composition of the ground material.
When GPR scanning is performed, it doesn’t identify the specific material inside the concrete. So, technicians use the characteristics of the scanned data to help identify rebar, PT cables, conduits, etc. Certain limitations do effect the scan data such has dielectrics, conductivity, access to the work area, depth of the concrete, type of material, etc.
What can Concrete Scanning Ground Penetrating Radar Find?
Embedded electrical services
When cutting concrete in commercial locations, it’s important to accurately detect electrical conduits embedded in it. If they aren’t detected before cutting, they might damage electrical services, resulting in power outages and safety hazards. Sometimes, random concrete cutting leads to increased repair costs.
Reinforcing steel
The primary role of reinforced concrete and reinforced masonry structures is to strengthen and aid the concrete under tension. GPR scanning detects this reinforcing steel before cutting or working on the concrete slab.
Voids
GPR technicians not only locate tangible objects under concrete, but they also locate empty spaces in the grade and subgrade below the concrete. Voids occur because of various forces on the ground, such as soil erosion, compaction, and pipe ruptures. Voids are difficult to detect by visual inspection as they are covered by concrete and grade materials. So, GPR scanning is preferred.
Concrete structure analysis
Sometimes, ground penetrating radar services are not used for detecting objects under concrete; instead, they are important for analyzing the content of the concrete structure. This technique helps in knowing the thickness of the concrete and getting information about reinforcing bars, which include their spacing and depth in the concrete. Engineers use these details to make decisions regarding the slab.
