		GPR waves allow you to identify objects and materials based on their dielectric properties. In relation to concrete, such objects may be built-in metal fittings, the bottom of the plate, a plastic pipeline or concrete voids. Concrete voids may be hazardous and need to be fixed urgently.
GPR Corescan may also be used to identify voids that sometimes form under concrete. This data is necessary for the timely filling of little cavities with concrete before they increase in size. An increase in voids may lead to a violation of the integrity of the concrete slab, for example, to its destruction or the appearance of cracks. This is because concrete has enormous compressive strength, but its tensile strength is very limited. Structural failure of the slab may result in subsequent injury, or worse.
