Ground Penetrating Radar (GPR) for Subsurface Void Detection

ground penetrating radar for subsurface detection in kansas city, st. louisGPR quickly, safely and accurately detects subsurface voids. Many states departments of transportation use GPR to assess necessary highway and road repairs. They have found the cost savings to be substantial and the disruption of traffic to be minimal due to the speed of the GPR units in providing real-time imagery. With GPR we can scan a larger area in a shorter time than x-ray units which saves money.

We use Ground Penetrating Radar to locate subsurface voids. Poorly compacted and consolidated sub bases can cause settling and cracking of concrete slabs. The true extent of these voids must be identified and located so the problem can be fully addressed.

GPR is the ideal solution for void detection. GPR "looks through" concrete slabs to image the sub base and precisely locate all voids without removing the concrete.

Once the voids are identified, PFT injects polyurethane foam that expands and fills the voids while compacting the surrounding soil and helping to prevent the problem from recurring in the future.
