Why Choose Direct Push Drilling

  • SMALL FOOTPRINT Direct push is ideal for smaller sites because it requires less space for operation and drills smaller holes.
  • PRODUCTIVITY In the right soil type, direct push can quickly produce a large number of high quality samples, generally up to 200 feet per day.
  • WASTE MINIMIZATION Direct push produces minimal investigation derived waste (IDW) because it does not require the continuous removal of drill cuttings to clear the hole, or additional fluids for cooling and lubrication.

SOIL SAMPLING

Soils samples can be collected in clear plastic (PVC), Teflon (PTFE), brass, or stainless steel liners, depending on project requirements. These liners can be capped and sent to your laboratory for analysis.

GROUNDWATER SAMPLING

Groundwater samples can be collected utilizing screen points, mill-slotted well points, peristaltic pumps, tubing and check valves, mini bailers, and screen implants. The method to be chosen for groundwater collection depends on the aquifer’s characteristics, sample contaminants, and the objectives of the project. Monitoring wells of up to four inches in diameter may be installed in the right subsurface conditions. The type of well completion will depend on the soil characteristics and the objective of the project.

DUAL TUBE SOIL VAPOR SAMPLING

The Geoprobe® Post Run Tubing (PRT) system can be used for soil-vapor collection. This system utilizes a three-way valve connected to the tubing: one running from the bottom of the boring, one to the purging pump and another to the sampling container, for an undisturbed soil vapor sample. ECTMFG also provides many other tooling and material configurations for sub-slab sampling.
