It uses static force and the dynamic percussion force of the GH40, GH60 or GH80 Soil Probing Hammer to advance small diameter sampling tools. It rearranges particles in the subsurface by application of weight and percussion to advance a tool string and produces no cuttings in the process.

How does a Geoprobe work?

Geoprobe sampling involves taking samples from a specific location at defined depths. It can happen from the ground level down, or beginning at a certain depth. For taking samples from ground level down, the rig drives an outer casing, with a drive shoe installed, into the ground.

What's a Geoprobe?

A geoprobe is a direct push technology that is used to obtain samples. The geoprobe uses percussion and static force to drive steel boring rods into the ground. Sampling with a geoprobe takes place below the surface at a multitude of depths depending on lithology.
