Geotechnical Engineering 

Our geotechnical engineers assess land in order to design appropriate foundations for large structures on soft ground. We’re civil engineering specialists and have significant experience with Kansas and Missouri soil and rock properties.

Low, Medium, High-Rise, and Industrial Engineering

  • Shallow foundation systems: spread footings, mat foundations, post-tensioned slabs
  • Intermediate foundation systems: Rammed Aggregate Piers (RAP)
  • Deep foundation systems: Drilled piers, auger cast piles, driven piling, micro-piles
  • Anchored structures

Earth Structures

  • Slope Stability including design and repair of failed slopes
  • Embankment Dams
  • Earthen embankments
  • Underground limestone mine development


Retaining Walls

  • Cantilevered
  • Mechanically Stabilized Earth (MSE) / Modular block systems
  • Soil nails / Tieback and anchored
  • Stacked Stone

Pavement Design

  • Rigid – Portland cement concrete
  • Flexible – Asphaltic concrete
  • Soil stabilization using fly ash or lime
  • Subgrade reinforcement using geotextiles and geogrids
