All work is performed in accordance with State Environmental and ASTM standards. Soil probing offers a quick and inexpensive technology to define site stratigraphy and delineate contaminant plumes, install monitoring wells and investigate property for real estate transactions. The rigs available from Aztech Technologies include a Foremost Mobile B3500. This rig offers more power and versatility than equipment of other manufacture. The drill is mounted on a four-wheel drive vehicle. Equipment includes both a soil probe hammer and rotary top heads. Operations can be switched from probing to drilling and back without moving the equipment from the hole. The Foremost/Mobile 3500 is equipped with a high torque rotary tophead, which enables the use of 6-5/8" hollow stem augers. The hydraulic mast drop enables operation in areas of low overhead clearance
