AET > Services > Geotechnical > Drilling and Testing

American Engineering Testing (AET) offers a highly trained, experienced staff using state-of-the-art equipment. Our drill crews normally consist of two skilled technicians trained to log borings, classify soils and bedrock, install monitoring wells or piezometers, and perform various in-situ soil or bedrock tests. As part of our quality control system, all soil and bedrock samples are returned to our laboratory for verification of material classification and log presentation. We use gINT software for computer-generated logs and certain test reports.

AET stresses safety while performing services. Personnel assigned to drill crews and subsurface sampling duties receive training that meets OSHA and DOT requirements. This training includes 40-hour and 8-hour refresher courses on hazardous materials handling, confined space entry, hazardous materials transport, random drug testing and other salient topics.

Recognizing how important efficient and reliable results are, we've established a fleet of sixteen modern drill rigs having a wide range of capabilities. Rigs are available ranging from small, portable units for limited spaces to various truck-mounted units to track or flotation-tire, all-terrain units. We have a large assortment of drill tools to tackle drilling tasks in most soil and bedrock situations.
