Geotechnical Engineering

Geotechnical engineering involves investigating and understanding conditions beneath the ground’s surface. Our geotechnical engineers assess land in order to design appropriate foundations for structures of all sizes. We are a seasoned engineering group with experience and expertise specific to the Kansas City area. Our influence can help improve the design of your foundation, make better use of your budget, and provide a higher degree of confidence that your project is being done right.

Foundation Engineering

Low, Medium, High-Rise, and Industrial Structures

  • 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
