  • sub-slab soil fluid samples are collected to evaluate vapor concentrations and the potential for these vapors to enter a building.
  • the collection of sub-slab samples can also be inconvenient to building occupants since it requires the removal of floor coverings and coring or drilling of the foundation slab.
  • One recommended method is using an electric hammer drill or rotary hammer to produce an inner pilot hole into the concrete slab. After the pilot hole is drilled, an individual must drill an outer hole to a predetermined depth using a larger drill bit. After the outer hole is finished, the individual must use the original tool to assure that the pilot hole is then drilled through the slab and several inches into the sub-slab material. Once the drilling is completed, a stainless steel probe is assembled and inserted into the pre-drilled hole. The probe is mounted as flush as possible with the surrounding slab to minimize the interference with pedestrian or vehicular traffic.
  • the probe has to be cemented into place to ensure that the probe assembly is air-tight with the foundation slab. Since the cement has to cure, an individual must come back at least one further time before sampling of the sub-soil may occur, further inconveniencing a homeowner or business.
