Complete your geotechnical investigation faster, easier, and safer when using a Geoprobe® geotechnical drilling rig. The low impact and maneuverability of the geotechnical drilling rigs allow for free movement on geotechnical investigation sites with limited access, such as next to foundations, inside buildings, or under power lines. But don&#;t be fooled by the small footprint. These rigs pack the pull and push power necessary to complete your geotechnical investigations for roadways, buildings, tunnels, and levees while also providing the control to fine tune your geotechnical soil testing.
For more Crawler Mounted Drilling Rigsinformation, please contact us. We will provide professional answers.
Make your geotechnical investigation quick and efficient with quality components like the automatic drop hammer and combo head along with tooling systems like the interlocking split spoon. With enough engineering to keep drillers out of harms way, fewer moving parts and loads of tooling storage make your geotechnical investigation safer. Making field operations simpler includes little touches like a measuring device on the drop hammer and indicator arrows to guide the sliding of the head. These all combine for increased productivity.
With efficient and effective versatility to complete SPT, DPT or CPT, complete your geotechnical investigations and expand opportunities for handling multiple types of job sites or offering more service lines to increase your profit potential.
With drill rig service shops in North Carolina, Pennsylvania, Florida, and Kansas, you&#;ll have service support nearby for your routine maintenance or more in-depth drill rig remounting and refurbishment work. Our service technicians are backed by our team of engineers to ensure solutions not bandaids to issues. And our production processes mean your geotechnical drilling rigs are constructed consistently and tested thoroughly to ensure easier service support.
Our team of engineers thrives on collaborating with drillers while they continually innovate new designs for our geotechnical drilling rigs. Our goal is to help maximize your success by making your job faster, safer, and easier.

Rotary drilling: This type of drilling digs a hole by grinding the rock with a tool under the effect of weight and rotation. It is mainly used in oil production. The cuttings are brought to the surface under the pressure of a drilling fluid that is injected into the drill string. Drilling fluid also helps consolidate the walls of the borehole, so it is not necessary to case it as the operation progresses.
Down-the-hole drilling (rotary percussion drilling or rotary hammer drilling): this type of drilling uses drilling rigs that drill with a rotary cutter (drill head) and hammer the bottom of the hole with a pneumatic hammer. The excavated material rises to the surface under the pressure of the compressed air used for the hammer. These drilling rigs are powerful and have high drilling rates, especially in rock. For artesian wells (wells where water naturally rises to the surface under groundwater pressure) or geothermal drilling, an air injection at the end of the drill pipe pushes the water up the borehole, allowing the operator to immediately determine the water flow encountered. This type of drilling is used for hard and cracked ground up to 4,000 meters deep. When the drilling bit is eccentric, the drilling can be done with a casing advancement system (installation of tubes by gravity) which reinforces the hole as the drilling progresses.
Top hammer drilling: this type of drilling uses drilling rigs that also operate on a percussion system, but one that remains outside the borehole. They are mainly used for small diameter drilling, for example for mineral exploration or the installation of tie rods in rock. This system is used for shallow boreholes, as there can be significant deviation due to the structure of the ground drilled through. These drilling rigs can operate in any direction however.
Auger boring: This is a type of rotary drilling using a worm screw (the auger). This type of drilling is mainly used for unconsolidated clay or sand terrain. The excavated material is directly brought to the surface by the worm screw. For deep drilling, it may be necessary to regularly raise the auger to empty it of its excavated material.
Core drilling: Core drilling is similar to rotary drilling, but it uses a crown to extract a sample, called a core, inside the tool.
Percussion drilling: consists in breaking the rock by dropping a tool, the drill bit, by gravity. This type of drilling can only be used vertically. To prevent the borehole from collapsing, it is necessary to case it as it is drilled. The cuttings are reassembled as soon as they interfere with drilling by replacing the drill bit with a flap valve bailer. The flap valve bailer is a type of tube equipped with a tilting flap in the lower part. This tilting flap allows the tube to be filled with excavated material which is then transported to the surface.
Pipe jacking: is mainly used to install horizontal pipes. The tube is pushed progressively by percussion, the excavated material being removed at the end of the drilling operation either by water injection or with an auger. This technique is used in particular to avoid transmitting vibrations to the surrounding buildings or to avoid digging a trench.
