Our professional team consists of licensed Geotechnical and Civil engineers and Engineering geologists, registered in the State of CA with decades of experience in geotechnical and materials engineering in the San Francisco Bay Area. We specialize in determining and finding a cost-effective way to design and build foundations for residential and multi-story commercial buildings and recommending solutions to resolve foundation distress problems.
We specialize in landslide investigation and recommend cost-effective repair strategies. We also specialize in designing various types of retaining walls (on spread footing or drilled piers), geosynthetic reinforced embankment, below grade structures, and performing slope stability, seismic, and liquefaction analyses. To learn more about all our geotechnical services, contact us today at O'Terra Geotech Group, Inc.
We look forward to working with you.

Foundation engineering involves the determination of the best suited and most economical foundation types and depth for our clients' projects based on the strength of foundation soils and rocks.
We provide geotechnical information, design data, and recommendations for slab-on-grade, mat foundation and drilled piers foundation to the project structure engineer.
We conduct foundation inspections and evaluations of the existing structures and provide written recommendations to the project structural engineer for repair such as underpinning.

At O'Terra Geotech Group, Inc., we can provide you with all your soil engineering needs.
Soils and foundation investigation involve soil borings, test pits, CPT sounding, using truck-mounted track-mounted and portable drilling rigs.
Standard Penetration Test (SPT) is conducted at 5' or less intervals.
Expansive soils are soils that experience significant volume change associated with changes in water contents.
These volume changes can either in the form of swell or in the form shrinkage and this is why they are sometimes known as swell/shrink soils.

When buildings to be constructed on existing slopes we investigate the condition and stability of the slopes, perform stability analysis using computer program and provide written recommendations.
For landslide project, we investigate the site, conduct foundation explorations and provide repair recommendations.
The investigations may include borings, instrumentations, and monitoring.
The repair solution may be drainage improvement, non-structural solution such as geo-synthetic reinforced earth (GRE) or structural repair involving various type of earth retaining structures.
