Concrete scan technology, sometimes called GPR scanning, is a nondestructive testing method that utilizes active radar, or GPR, in-situ to evaluate the structural integrity of a structure in position and detect hidden buried utilities before concrete cutting, drilling, etching, etc. Several GPRD scanners are available for both industrial and residential applications, depending on your requirements. A typical GPRD scanner can perform several common operations such as:
How to Do GPRD Scanning For Subsurface Utility Finding
The basic technique of a concrete scan involves two-dimensional scanning (autograph) and surface survey; with a rister consisting of two steel plates, one placed above the other, with an electrical current passing through the plates via an electric source. The first plate, called the “ground penetrating radar reflector”, is positioned above the second, called the “scanner” plate. This technology can utilize two or more scans, which can identify buried utilities in a much faster and thorough manner.
One of the most commonly used GPRD techniques is the vertical surface scan, which locates all buried utilities as well as all potential buried and exposed utilities. For underground utility locating, the vertical concrete scan is used to locate buried electrical and gas lines as well as any fiber optic or communications lines. In addition, this technology can also be utilized to locate piping connections. In addition, when performing a concrete scan, the GPRD technology utilizes a number of other key components such as: radars, software, databases, and data collection systems.
