Geotechnical Engineering

Stop guessing with Geotechnical and Geophysical Services!


While surprises are a fact of life, they don’t need to be part of your engineering or construction project when it comes to what’s underground. The stability of the foundation of a building, bridge, pavement section, or any other structure built on soil depends on the characteristics of the subsoil. Our geotechnical and geophysical teams are experts at determining what’s below the surface.


Our team includes professional engineers, LEED® APs, certified field technicians, and a testing laboratory qualified by the U.S. Army Corps of Engineers to perform soil and materials testing. We plan and execute subsurface explorations to fit your project needs and cost constraints. After the exploration is complete and all potential hidden structures, such as sinkholes or underground storage tanks, are revealed, our geotechnical team will tailor a custom solution for you to keep your project on track and on budget.

Ground Penetrating Radar (GPR) uses radar pulses to image elements below the surface. It can be used to detect subsurface voids and cracks.

We use scientific evidence to provide you with the most thorough view of your project. A few of our tools include Ground Penetrating Radar (GPR), Shear Wave Testing, and Electromagnetic Induction (EM). In addition to avoiding surprises, a proper geotechnical or geophysical investigation can save your budget. For example, shear wave testing, which measures the susceptibility of the ground to shaking during an earthquake, almost always provides a higher International Building Code (IBC) Site Class than that obtained from borings. The higher class can result in saving hundreds of thousands of dollars on design and construction.

With broad experience in the design of shallow and deep foundation systems and integration of subgrade densification and intermediate foundation systems, we strive to cultivate the most efficient foundation solution. Our geotechnical experience includes residential and commercial buildings, government facilities, slope evaluation, transportation structures, pavement design and more. Coupled with our construction inspection services, we can provide the assurance that your design is implemented in the manner that it was intended.

Electromagnetic Induction (EM) quickly and inexpensively detects the conductivity of earth and non-earth materials by emitting an electromagnetic field and measuring the strength of the secondary magnetic field created by it.
