Outline of soil liquefaction due to unstable layer after an earthquake.

Guide To Soil Liquefaction

Soil liquefaction is a geological phenomenon that changes the structure of the Earth’s soil. External stressors loosen the soil particles, changing the ground into a less stable base for buildings and other structures. Soil liquefaction presents risks to construction companies building in high-soil liquefaction areas, such as California. If builders construct on top of loose…

Why Should You Hire a Geologist?

A geologist ensures the safety of the ground you are building on by testing for groundwater, percolation, soil gas, and other government-required tests. Hiring a geologist saves construction projects time and money by creating scientifically-backed design recommendations for anything from a septic tank to the foundation of a large building.   If you want to…

Alabama Hills: A California Geological Treasure

On the eastern slope of the Sierras, just three hours north of Los Angeles, lies the deceptively-named “Alabama Hills” — a wonder of geology and Earth science. Sitting around 5,300 feet in elevation, this rolling vista of rock formations, classic Western landscapes, and spectacular natural weathered arches is a treat for anyone who visits (not…

soil engineering reports

Soil Engineering Reports: Why You Need Them and How They Work

Also known as soils reports and geotechnical investigations, soil engineering reports are investigations undertaken by geotechnical engineers to discover the properties of soil and earthworks at a proposed or existing building site. These geotechnical soils reports help developers understand the status of the ground where they plan to build structures, and they also help contractors…

What Is Farming Carbon Capture?

In recent years, discussions surrounding climate change have focused on agriculture, and animal agriculture in particular. The amount of methane emitted from livestock accounts for a significant percentage of the overall carbon emission volume. Since the advent of concentrated animal feeding operations (CAFO), this problem has intensified — beef raising operations alone count for half…

All Geotechnics Is Local

Many of us have heard this famous expression: “All Politics is Local.” Incidentally, the same idea applies to the geotechnical and environmental engineering profession. In that sense, we can say “All Geotechnics is Local!” Local building codes, guidelines for work in the profession, and standards of care vary greatly by both region and local agency…

What Are “Modified” Soils Reports?

Considering some new construction on your home? Here’s something you should definitely familiarize yourself with: some jurisdictions (such as the city of Glendale) allow for analyses known as “modified soils reports” for small addition projects. So, what are modified soils reports? Typically these involve a short site visit by a soils engineer, followed by a…
