Direct Push Drilling & Sampling
Direct Push or Dual Tube Sampling Systems are efficient methods of collecting continuous soil cores with the added benefit of a cased hole. Dual tube sampling uses two sets of probe rods to collect continuous soil cores. One set of rods is driven into the ground as an outer casing. These rods receive the driving force from the hammer and provide a sealed hole from which soil samples may be recovered without the threat of cross contamination. The second, smaller set of rods is placed inside the outer casing. The smaller rods hold a sample liner in place as the outer casing is driven one sampling interval. The small rods are then retracted to retrieve the filled liner.
Using one of Cortek’s machines, you can drive tools to obtain continuous soil cores or discrete soil samples and you can drive samplers to obtain groundwater samples or vapor samples. You may also insert permanent sampling implants and air sparging points.
