Geotechnical Engineering and Construction Materials Engineering and Testing Services

We provide geotechnical engineering to assess specific site soil and groundwater conditions and design earth structures (slopes, channels, and dikes), foundations (retaining walls, bridges, buildings, tanks), and subsurface structures (clarifiers, lift stations, buried utilities, tunnels) to economically achieve the specific project objectives.

We engineer and test materials such as soil, concrete, and asphalt, so you get what you pay for, and the project performs as or better than expected including owner verification testing, pavement subgrade stabilization, and shrink-swell mitigation mix designs, and construction observation of drilled shaft, auger-cast-pile, driven pile, shallow spread footing, and mat foundations.

Recent Projects

We focus on public sector infrastructure projects. We deliver superior engineering knowledge and an outstanding experience working together.
