Geotechnical Engineering

Geotechnical engineering is a branch of civil engineering dealing with the analysis, design, and construction of foundations, slopes, retaining structures, and other systems that are made of or supported by soil or rock. Geotechnical engineering is essential to the foundation design for every existing or new structure, highway, bridge, tunnel, harbor, airport, water line, reservoir, etc. Commonly, the geotechnical engineering service comprises a study of subsurface conditions using various sampling, in-situ testing, and/or other site-characterization techniques, performing engineering analyses, and providing geotechnical solutions and recommendations to build improvements.

Geo-Advantec team has performed numerous geotechnical engineering evaluations and investigations for different types of projects worldwide and in Southern California. Our projects include developments of schools and colleges, seismic retrofit of structures, solar energy, cell towers, roads and bridges, tunnels, cooling towers and stacks for power plants, parking structures, main water and sewer lines, recycled water and utility lines, sports facilities, parks, and recreational facilities. We provide comprehensive soils/underground studies based on the project-specific requirements. The following is a list of services under this category:
