Ground Penetrating Radar

Ground Penetrating Radar (GPR) is a safe, extremely fast, and accurate tool we use to locate materials within a concrete structure.

How it works: GPR emits electromagnetic energies through a concrete slab. This energy travels until it hits an object within the concrete. A majority of the energy is reflected off the object and is returned to an antenna receiver. The amount of signal return is dependant on the object’s dielectric make-up; the higher the dielectric constant, the higher return of signal. Older concrete and plastics generally have a low dielectric constant and a low signal return, while steel, water, and mineral-rich mediums have a high dielectric constant and a higher return of signal. Additional information regarding GPR is available in the Frequently Asked Questions section. 

"Subsurface Imaging has helped me save my contractors thousands of dollars.
Their employees are well trained and they use state of the art equipment. Their greatest strength is their continual effort to seek out new technologies and techniques to improve their efficiency or increase the reliability of the information they provide. I highly recommend using their company."
