Direct Push Drilling / Geoprobe

Olympus Technical Services uses direct push drilling for most environmental and geotechnical drilling and subsurface sampling.

Why Choose Olympus Direct Push Drilling Services

Direct push technology pushes tools and sensors into the subsurface using a percussion hammer and vehicle weight. This method can be used to achieve sampling depths of up to 100 feet depending on soil conditions.

Olympus owns two Geoprobe 78 Series combination drill rigs: An all-terrain 7822DT and a truck-mounted 7800. With our skilled operators at the controls, our direct push drilling services outperform other alternatives in several key areas:

  • Our rigs generate a fraction of the drill cuttings that traditional rotary drilling rigs do. That is important because drill cuttings from soil investigations may be hazardous and proper disposal of the cuttings can be expensive.
  • Our rigs push through soil twice as fast as truck-mounted, hollow-stem auger rigs, so we can get the job done faster.
  • The size and maneuverability of our rigs make mobilization faster and more economical than traditional drilling rigs.
  • Our rigs feature an adjustable, oscillating drill mast which permits us to drill on slopes and uneven surfaces. We can even drill at an angle to get under building foundations and other surface obstacles.
  • We can drill through, and install wells in, surface pavement (both concrete and asphalt).

“We worked with Olympus to demolish, dispose, and backfill two buildings containing hazardous materials. Olympus’ crew was receptive to our requests, adapted to changing site conditions, suggested ways to increase efficiency, and didn’t sway from their proposed cost. Together we changed the site from dilapidated hazardous buildings to a clean construction-ready property.”

“Olympus Technical Services won a major demolition bid with FCEDA. The bid was fair and the work started on time and finished in advance of our deadline. It was a difficult job with several unknowns that caused delays, change orders, and equipment breakdowns. Throughout, the team from Olympus was professional, flexible, and made sound recommendations. They were great partners on a difficult project. Because of this experience, we have recommended them to many of our partners.”
