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.
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.
We provided expert testimony on the causation of the slope failure.
We investigated failure of a slope and monitored the remedial work. The remediation consisted of adding a berm to flatten the slope.
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.
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.
We provided expert testimony in a PG&E gas pipe explosion case. Trench pipe cover and backfill compaction was at issue.
We identified the cause of concrete cracks in 144 RV pads. Provided expert testimonial.
