Geoprobe Systems

What's Behind Our Name
Geoprobe a brand name of high quality, hydraulically-powered, direct push machines that use both static force and percussion to advance sampling and logging tools into the subsurface. The first Geoprobe brand machine was built for the Environmental Protection Agency in 1988.

The Geoprobe brand name refers to both machines and tools manufactured and sold exclusively by Geoprobe Systems in Salina, Kansas. Geoprobe tools are used to perform soil core and soil gas sampling, groundwater sampling, electrical conductivity and contaminant logging, grouting, and materials injection.

Soil probing techniques can be thought of as a subcategory of what are commonly referred to as 'Direct Push' techniques. Direct Push refers to tools and sensors that are 'pushed' into the ground without the use of drilling to remove soil or to make a path for the tool. A Geoprobe direct push machine relies on a relatively small amount of static (vehicle) weight combined with percussion as the energy for advancement of a tool string.

Using a Geoprobe direct push machine, you can drive tools to obtain continuous soil cores or discrete soil samples. You can drive samplers to obtain groundwater samples or vapor samples. You can insert permanent sampling implants and air sparging points. You can drive a conductivity sensor probe to map subsurface lithology. You can install small diameter monitoring wells. In fact, the Geoprobe machine has been used to perform many of these functions to depths of 100 feet (30m) or more where the geology and soil conditions are appropriate.
