Geotechnical Engineering Services
At LOI, it all starts from the ground up.
What Is Geotechnical Engineering?
Geotechnical engineering is the study of how soil, rock, and groundwater behave beneath and around a structure. Before anything gets built, the ground has to be understood: its composition, its strength, how it moves, and how water flows through it. Geotechnical engineers take that knowledge and turn it into design recommendations that keep foundations stable, slopes secure, and pavements performing for the long haul.
Why It Matters
Every structure sits on or in the ground, and ground conditions are never the same from one site to the next. Without proper geotechnical analysis, projects risk foundation failure, unexpected settlement, slope instability, or costly redesigns mid-construction. A thorough geotechnical investigation up front saves time, reduces risk, and gives designers and contractors the information they need to build with confidence.
What We Do
LOI’s geotechnical team provides a full range of services to support your project at every stage, including:
- Subsurface drilling and sampling
- Foundation recommendations for various structure types
- Pavement recommendations for roadways and site development
- Slope, earth retention, and embankment solutions
- Settlement, infiltration, and groundwater assessments
- Geotechnical reports for vertical, roadway, utility, and site projects
- Site reconnaissance and geologic hazard identification
- Geo-structural design for retaining walls and shoring systems
Our Process
On-Site Geotechnical Investigation
We drill borings, collect samples, and perform field testing to build a detailed picture of your subsurface conditions.
Laboratory Testing
Soil and rock samples are tested in the lab for strength, moisture content, plasticity, and other properties critical to design.
Engineering Analysis and Recommendations
Our engineers analyze the data and deliver a geotechnical report with clear design parameters and construction recommendations.
Construction Monitoring and Observation
We stay involved during construction to verify that field conditions match our findings and that work is performed in accordance with our recommendations.
