Geotechnical Engineering, Material Testing & Engineering Technology

Montana Engineering Firm Serving Bozeman, Kalispell & Surrounding Areas

Geotechnical engineering is the branch of civil engineering concerned with the analysis, design and construction of foundations, slopes, retaining structures, embankments, and other systems that are made or supported by soil or rock. All civil engineering projects should start with an adequate geotechnical investigation and analysis to determine what subsurface conditions are present at a site and how those conditions will impact the proposed construction. C&H Engineering is experienced in performing subsurface investigations and has an in-house laboratory to assist you with all your geotechnical engineering needs.

Geotechnical engineering services provided by C&H Engineering include:

  • Subsurface exploration and analysis
  • Deep and shallow foundation design
  • Estimated settlement of foundations
  • Retaining wall design
  • Flexible and rigid pavement design
  • Slope stability assessment
  • General earthwork construction considerations
  • Groundwater conditions
