Our Services

With the expertise of our drillers, top notch training on the nuances of drilling, and the detailed operation of our reliable equipment we have been able to narrow our focus to provide a best-in-class drilling operation.

  • A method of rotary drilling that uses air to remove cuttings from the hole. Generally used in hard rock where water loss can be expected or you are looking for water.

  • A method of drilling using a continuous flight tool (auger) that carries up soil cuttings as you drill deeper. Types continuous-flow auger (CFA) and hollow-stem auger (HSA).

  • The art of collecting continuous soil, sands or rock sample. Types such as shelby tubes, split spoons, 5’ continuous sampler, California sampler and continuous rock coring are commonly used.

  • Using a hydraulic or pneumatic hammer to collect soil samples. Generally preformed by Geoprobe equipment.

  • Subsurface soil and rock investigation with field testing data logged for lab testing.

  • The practice of injecting chemicals to clean up environmental issues or stabilize soil formations.

  • The practice of setting a well to monitor water level, water flow and water migration. Also used to monitor water table contamination.

  • The practice of setting a Piezometer to check water levels and triangulate water flow.

  • The art of cutting a continuous 5' to 10' sample of rock for the lab test such as compressive strength, tri-axle sheer, and unconfined test.

  • The technique of using 24" direct push sample that is 2.75" in diameter in clay formations used in lab tests such as compressive tests, swell tests, and plasticity index (PI).

  • A shallow, small diameter well to test and/or monitor subsurface vapors.

  • A technique used in sand and gravels for measuring compressive strength. Basic test involves an 18” length consisting of three sets of 6” counts or 50 hammer blows if less than 6”.

  • A method designed by TxDOT as another tool to recover compressive strength values with a 170 lbs hammer.

  • The act of removing the riser, screen, and casing from a well shaft. The well shaft is normally sealed to prevent contamination.

  • The technique of using water (wet or mud rotary) to remove cutting debris from the hole and advance bore hole to depth.
