Colorado Springs Concrete Scanning Projects that Penhall Technologies Has Worked On

Ground penetrating radar examination finds steel reinforcement in concrete

Penhall Technologies was contracted for a job in Weld County, Colorado. The job mainly consisted of scanning several areas of a newly constructed concrete road. The client mentioned that his reason for hiring Penhall Technologies for the GPR examination was to identify the placement of steel reinforcing dowels embedded in the concrete. Our skilled analyst arrived on site and began the procedure by marking the area to be scanned (as seen in the picture). Then, the Penhall Technologies’ analyst scanned the area and the results were drawn in red marker, yielding a comparison with the client’s required layout. An approximate depth was also recorded at each end of the dowels. This procedure was then repeated in several areas of the road.

The client was in need of a ground penetrating radar scanning method to prove to the Department of Transportation that the road reinforcement was correctly installed. The client mentioned that they previously used a method known as MIT to locate the alignment and depth of reinforcement. However, the client was skeptical of the results when several areas of the road failed under that inspection, and that is when he decided to hire our services. Our Penhall Technologies’ analyst was able to show through ground penetrating radar, also known as GPR,  that the reinforcement was within compliance of the Department of Transportation.

A lot of times, Penhall Technologies goes in to confirm a previous concrete scanning job. When it comes to concrete, it is always wise to scan first and make sure that there are no underground hazards lying the concrete before any cutting, coring, or other modifications. This eliminates a costly demolition and reconstruction project for the client, saving him time and money.
