Foundation Soils Assessment

GeoStrata provides foundation recommendations for all types of structures, including residential and commercial buildings, bridges, utility plants, and waterfront structures.

Our assessments cover foundation type selection, bearing capacity calculations and settlement analysis, along with mitigation strategies for problematic soil conditions such as expansive or collapsible soils.

• Foundation type selection
• Bearing capacity
• Settlement analysis
• Expansive soils
• Collapsible soils

Field Instrumentation & Monitoring

We provide instrumentation installation, calibration, monitoring, data reduction and analyses for landslide and settlement evaluations.

Equipment includes slope inclinometers, piezometers and extensometers, deployed for both short-term construction monitoring and long-term hazard programs.

• Slope inclinometers
• Piezometers
• Extensometers
• Settlement monitoring
• Data reduction & analysis

Pavement Design

Pavement design recommendations include subgrade preparation and compaction requirements, and the thickness and type of base materials required.

We cover both flexible and rigid pavements, Superpave mix designs, and removal and reconstruction projects.

• Flexible pavements
• Rigid pavements
• Superpave
• Subgrade preparation
• Removal & reconstruction

Earthen Dams & Embankments

GeoStrata handles the design and permitting work associated with earthen dams and embankments, including permits from departments of environmental quality and divisions of oil, gas and mining.

• Dam design
• Embankment design
• DEQ permitting
• Oil, gas & mining divisions

Retaining Structures

We design both temporary and long-term retaining structures, selecting the system that fits the site, the schedule and the loads.

• Soil nails
• Mechanically stabilized earth (MSE)
• Modular block systems
• Temporary shoring

Slope Stability Assessment

Stability analyses for both planned and existing slopes, using current industry-standard analysis software and field data from our own instrumentation programs.

• Planned slopes
• Existing slopes
• Global & local stability
• Remediation design

Seismic Design & Liquefaction Analysis

Our seismic work encompasses ground motion studies, seismic lateral earth pressure calculations, and liquefaction evaluation for saturated granular soils.

This is central to work along the Wasatch Front, where seismic and liquefaction hazards drive foundation and mitigation decisions.

• Ground motion studies
• Seismic lateral earth pressure
• Liquefaction triggering
• Post-liquefaction settlement
• Mitigation design
