W hether purchasing new boots or a new car, people want the most value for their money. This is espe- cially true for drillers purchasing geotechnical drills for water well drilling, soil sampling, or standard penetration testing. A well thought-out purchasing decision maximizes return on investment. While some consider choosing the cheapest drill manufacturer as the easy answer, price should never be the only factor. A geotechnical drill that achieves a high return on invest- ment withstands challenging soil conditions time and time again as well as comes with quality support from a trust- worthy manufacturer. Before purchasing a drill—consider application, quality, and service. Assess the Application Begin by determining which type of formations your drill crew will encounter. Water well drillers face major expenses when their drill can't meet the challenges of their project's location. For example, pulling a poorly manufactured drill over rough terrain can damage the equipment, which can delay a project for repairs as well as risk the operator's safety. Depending on the drilling formation, drill crews require either a mechanical or hydraulic drill. Each drill is suited for certain soil conditions, ranging from sand and clay to gravel formations. Three key considerations for selecting geotechnical drills that maximize return on investment. By Joe Haynes Geotechnical drills such as the Lone Star 300H+ can drill in a variety of formations.
