Geotechnical Engineering1

Expertise in the field of geotechnical engineering has been a key element in the growth of Earth Systems group of companies. The firm's staff possesses high technical competence and sensitivity to important project requirements such as scheduling, government regulations and client needs.

Our facilities provide a full complement of geotechnical engineering services. The firm maintains in-house laboratory-testing facilities fully equipped to perform tests required to evaluate most geotechnical engineering problems. The firm also maintains in-house drilling capabilities with both continuous flight auger and hollow stem auger equipment. Sampling capabilities include the standard penetration split spoon samplers, split barrel samplers and Shelby tubes.

Earth Systems group of companies professional staff has extensive experience in solving geotechnical problems. In addition to the prediction of settlement and allowable bearing capacity which are basic to all foundation studies, the firm also provides evaluations of seismic design criteria, slope stability, subsidence, collapsing soils, expansive soils, liquefaction and seepage. Depending on the nature and complexity of the problem, computer analyses are employed using the latest programs and techniques.
