Before cutting, coring, or drilling any concrete, certain steps should be taken. The two common and effective non-destructive methods are concrete x ray and Ground Penetrating Rader (GPR). There are advantages and disadvantages attached to both, and it is important to understand their differences and benefits to make the right choice.
GPR waves are equal to those of a cell phone or wifi network while X-rays needs a 50 feet clearance before usage for safety reasons. Generally, GPR is the cost-effective option and the faster method of concrete testing. The clarity of GPR is high but does not give the same resolution in concrete as x-ray. Concrete slab x rays target elevated slabs or the renovation of concrete wall surfaces where both sides of the structure are accessible. In GPR you only need one side of the surface accessible.
