Few Representative Projects

Foundation Settlement Investigation and Remediation

We found the causation of foundation settlement and provided methods to remediate. The picture above shows foundation jacking we recommended..  We performed subsurface investigation, wrote the geotechnical report, and provided monitoring during remediation. 

Unstable Foundations Due to Expansive Clay Soil

We performed a geotechnical investigation and  identified the causation of distress in 110 homes. We testified in federal court.  The court awarded in favor of our client.

Failing Slope Under a Liner - Wastewater Pond

We provided expert testimony on the causation of the slope failure.  

Typical Projects

Failure of Slope and Remediation

We investigated failure of a slope and monitored the remedial work.  The remediation consisted of adding a berm to flatten the slope. 

Post-Fire Concrete Evaluation

We evaluated concrete foundations and walls exposed to fire.  We performed destructive and non-destructive testing, identified concrete members to be kept and the ones to be removed and replaced.   Wrote a report to summarize our findings.  

Post-Fire Shotcrete Evaluation

We evaluated a 22-foot high shotcrete retaining wall after exposure to fire. Performed destructive and non-destructive testing, wrote a report to summarize findings.

Personal Injury - Gas Pipe Explosion

We provided expert testimony in a PG&E gas pipe explosion case.  Trench pipe cover and backfill  compaction was at issue.

Concrete slab-on-grade Distress-RV Park

We identified the cause of concrete cracks in 144 RV pads. Provided expert testimonial.
