Locating Piles Beneath A Concrete Slab On Grade – Virginia

Ground Penetrating Radar Systems was recently called to locate piles beneath a concrete slab on grade at NASA in Hampton, Virginia. Scope of work was to scan a 30’ x 30’ area in the basement of a building to locate and map out underground piles so the engineers on site could core drill and test the composition and structure of the existing piles. They were not sure if the piles were concrete or possibly made of a wood material. There were several piles that were said to be in the area according to old drawings from the building. We also were asked to map out the rebar in the slab so they could get a clean core sample when they went to drill by the piles. Ground Penetrating Radar is an effective and efficient way of locating material in a concrete slab and underground. It also allows us to provide a depth to how deep the material is.
