Geologic Hazards Studies

Geotechnical engineering is the branch of civil engineering concerned with the behavior of earth materials. It uses the principles and methods of soil and rock mechanics to solve engineering problems and design engineering works. It relies on the knowledge of geology, hydrology, geophysics, and other related sciences.

RMA Group primary geotechnical exploration services uncover unforeseen issues and ensure structural integrity and longevity, using data from soil and rock samples to expose risks and make site-specific remediations.

Our staff of registered civil and geotechnical engineers, professional geologists, and certified engineering geologists work with our clients to understand their needs and develop the best geotechnical procedures for each project.

We have the most comprehensive laboratory resources available in California.

Companies owns and operates facilities in the Inland Empire, Los Angeles, San Diego, and the Sacramento Valley strategically located to service projects throughout the state. We also have a fleet of self-sufficient mobile labs to serve our clients’ needs in remote areas of the state.

Soil mechanics and rock mechanics

Because all foundations rest on the ground, understanding the ground they rest on is critical to the viability of your construction project. Our geotechnical engineers specialize in rock and soil mechanics, providing analysis of properties such as permeability, strength, and density that ensure your project starts on solid ground.
