Geotechnical Site Analysis

GMU has more than 40 years experience evaluating soil and rock conditions for clients before, during and after construction to verify stability, meet performance goals and reduce the potential for unexpected problems.

GMU’s engineering geologists and geotechnical engineers are specialists in evaluating soil, rock and groundwater conditions for proposed and existing development.

From the planning and design phase through construction and beyond, GMU has the specialized expertise needed to see the job is done right the first time.

	Slope Stability Analysis GMU reviews soils conditions for planned hillside development and analyzes the stability of existing and proposed slopes. Our engineering geologists and geotechnical engineers are well trained in identifying potential landslides and providing solutions to stabilize slopes and allow for development.
	Seismic Hazard Analysis GMU’s engineers and geologists perform seismic-hazard analyses to determine the ground motion anticipated at proposed and existing developments. GMU provides site-specific responses and has experience with California’s wide range of soil and rock conditions.
	Geotechnical Instrumentation GMU’s staff is experienced in installing and monitoring a wide variety of geotechnical instrumentation and in-place monitoring systems, including slope inclinometers, peizometers, extensometers and strain gauges.
	Soil and Rock Testing GMU maintains a complete soil and rock mechanics laboratory, which allows the company to more quickly provide feedback and solutions to our clients’ geotechnical issues. The lab is approved by both the California Department of Transportation and the County of Orange Materials Testing Division, and is one of few labs that provide triaxial strength, permeability, pavement and corrosion testing.
	Seismic Refraction/Hard Rock Studies GMU has more than four decades of experience providing seismic refraction services for hard rock studies, which allow clients to more effectively plan their infrastructure and development projects.
	Fault Investigations GMU’s geologists have performed or directed fault investigations in various regions of Southern California. Our fault investigation team is highly skilled in interpreting geomorphology, structural geology, trench exposures and fault-related features.
	Liquefaction Analysis GMU is frequently called upon to perform detailed and comprehensive liquefaction, seismic-settlement and lateral spreading studies. We perform analyses on both proposed and existing developments using state-of-the-art techniques, and propose solutions to mitigate the potential hazards of liquefaction.
	Site Exploration GMU investigates subsurface geology and geotechnical conditions using a wide variety of drilling techniques and geophysical methods.
