A Geoprobe® is a hydraulically-powered, percussion probing machine designed for the geotechnical and environmental industry. The first unit was built for the Environmental Protection Agency in 1988.
Direct push refers to the method of pushing tools into the ground without the use of drilling to remove soil. A Geoprobe® rig relies on a relatively small amount of static weight combined with percussion as the energy to advance the tool string. Using a Geoprobe® rig you can advance tools into the subsurface to collect continuous soil samples, discreet soil samples, groundwater samples or soil vapor samples. In addition, you can also install small diameter temporary or permanent monitoring wells. When the soil conditions permit, samples can be collected with a Geoprobe® from depths in excess of 100 feet.
The Probing Company owns and operates the following direct push sampling equipment.
