Geotechnical Engineering

Honoring the spirit of the great Karl Terzahgi. Geotechnical engineering is a relatively new field, only formalized into a discrete engineering discipline over the last 80 years. The Duffield geotechnical engineering firm, serving PA, MD, NJ, & DE, is proud to be part of that evolution with the first large scale geosynthetic installations in the USA; involving innovative reuse of materials, challenging foundation designs, earthworks, and soil/structure work.
