Auger Drilling
Auger Drilling
Roschen is the leader in Direct Push Technology. However, we are not limited to percussion probing tools. Roschen has a wide range of auger tooling to fit your needs regardless of your scope of work. With the simplicity of a single bolt or pin, we can switch over from Direct Push to Auger Drilling in a matter of minutes. The list of tooling includes concrete coring capabilities, 2.5” & 4.5” solid flight, and 3.25”, 4.25” & 6.25” hollow stem augers.
Advantages
• Ability to install conventional 2” and 4” ground water monitoring wells
• Quickly run pilot holes through frozen ground or asphalt
• Easily install large diameter tooling for Soil Vapor Extraction (SVE) and downhole monitoring systems.

The Standard Penetration Test (SPT) and Cone Penetrometer Test (CPT) have become industry standards for subsurface geotechnical investigations using small diameter (<8-in. [20-cm]) borings and soundings. Both procedures have evolved over a period of 100 and 70 years, respectively, and have been adopted as ASTM standards. Each procedure has certain advantages over the other, but both can elicit incorrect data under particular subsurface conditions that are often overlooked, depending on the experience of field personnel operating or logging the tests. This paper seeks to explain the operative assumptions employed in both procedures, highlight the various corrections that are commonly employed, and warn the reader of common errors in interpretation.
The article concludes by stating that, under most conditions, the joint employment of SPT and CPT together has the greatest potential for characterizing sites correctly.
