Filling some or all of the cores with concrete, with or without reinforcing steel, offers much greater resistance to bending; however major performance and durability problems can arise if the reinforced cores are not fully filled with concrete. The question is, how can you tell? Ground Penetrating Radar offers a simple and effective solution...
