What is Geoprobe Drilling?

A Geoprobe is a hydraulically-powered, direct push machine that uses static force as well as dynamic percussion force to drive steel boring rods into the sub-surface at a variety of depths in order to assist in sub-surface sampling. The use of the direct push technique refers to tools being pushed into the ground without the use of drilling to remove soil or to make a path for the tool. The Geoprobe has become a quick, clean, and economical upgrade from the conventional environmental drilling equipment. It is able to work in areas not reachable by other drill rigs. By attaching a variation of sampling tools to the steel bore rods, the Geoprobe is able to collect soil, soil-gas, and groundwater samples. If a variety of electronic probes are attached to the steel bore rods the Geoprobe is capable of providing continuous in-situ measurements of subsurface properties (soil core sampling, discrete soil sampling), coring for monitor well installations, and more.

The Geoprobe direct push technology is also more cost effective than using conventional drill rigs when completing soil borings or installing wells. The use of direct push tools makes sampling speeds much faster, and fewer wastes are generated for disposal. Also, using test borings by direct push technology provides accurate ground water sample results, defines the water table interface, and can be used for the measurement of other physical parameters for in-site investigations.

Some Geoprobe Advantages Over Conventional Drilling Include:

. Accurate Soil Profiling: Undisturbed soil cores allows for vertical profiling capability in order to generate three-dimensional profiles of a site.

.Accurate Groundwater Profiling: Direct Push drilling is capable of collecting depth-discrete groundwater samples to detect contaminated layers.

.Sample Quality: Soil samples recovered in plastic liners for volatile organics are not exposed to the atmosphere before dispatch to the laboratory.

.Cleanliness: There is no water or drilling muds present during direct push boring.

.Rate of Work: The direct push boring provides data at a faster rate when required.

.Reduced Drill Spoil: Dual-tube sampling allows for a smaller volume of drill spoil required for safe disposal.

.Mobility and Access: With the Geoprobe you have access to confined areas.
