Ground Penetrating Radar (GPR) is a high resolution geophysical method for investigating underground structure. One of the most useful nonintrusive site investigation application to accurately locate hidden voids. Clear information is provided about the presence of subsurface voids, often at a fraction of the cost of traditional intrusive methods.
There are many subsurface voids that might represent critical safety issues and other concerns – washouts or settlement gaps beneath roadways or floor slabs, ungrouted masonry cells, bubbles in concrete pours, tunnels, mine workings, vaults, and incipient sinkholes or soil pipes. All of these can be detected using nonintrusive geophysical techniques.
While the structure itself may have no reason to fail, it can often be what surrounds the structure that makes the difference. Where there is a void, the material may move and settle, undermining the structure over time.
We can provide valuable information about target location or asset evaluation with effective survey results.
