Ground Penetrating Radar (GPR) is extremely safe for both operators and the public, it does not emit harmful radiation. Unlike X-rays, which use ionizing radiation, GPR is a non-destructive, non-invasive technology that uses high-frequency radio waves to create images of the subsurface. The power of the radio waves is very low, comparable to a Wi-Fi signal or a cell phone.

That depends on slab composition, reinforcement density, and site conditions. In typical slabs with access from one side we often achieve clear results up to 12 inches (30cm) deep, but two-sided access extends beyond this; we’ll advise though if conditions limit penetration.
