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. We’re proud to be part of that evolution with the first large scale geosynthetic installations in the USA; innovative reuse of materials, challenging foundation and soil/structure innovation.
