EST provides full-service geotechnical services. It is EST’s mission to exceed the client’s expectations by providing timely and accurate geotechnical services. EST has the drill rigs outfitted with the equipment needed to provide the geotechnical service on time. EST has a full-service testing laboratory at four Oklahoma locations to provide a full range of geotechnical and soil testing services. The staff has the experience to provide accurate results and is fully capable in providing any geotechnical service needed. EST has seven (7) professional engineers, five (5) State certified drilling operators, and over ten (10) State certified laboratory technicians.

Design and construction of functional and cost-effective structures require a thorough understanding of local soil, rock and groundwater conditions. EST provides a wide range of services to support all phases of a project, from preliminary design through completion of the building process. Each local EST office, with access to the extensive geotechnical experience and expertise of engineers, geologists and technicians throughout our company, can help to assess the construction and long-term performance risks associated with subsurface conditions. We participate as a vital member of the project team, focusing on project objectives and using innovative technologies to provide practical design recommendations.  EST has the people, software, and equipment to provide any geotechnical service needed in a timely manner according to specification. Below is a listing of some geotechnical operations EST is capable of performing.   For additional information contact Corby.Key@estinc.net
