Our Equipment

We take pride in our wide selection of equipment. All of our rigs are equipped with automatic hammers for geotechnical sampling. Each rig is easily converted to rotary wash drilling. All equipment is serviced and maintained regularly. Equipment is inspected each morning prior to operating.
