Geotechnical Hazard Assessment

Evaluation of geotechnical hazards including slope stability, landslide risk, seismic hazards, and liquefaction potential. Ground movement assessment, mitigation, and long-term performance planning for critical infrastructure. Supported by instrumentation: inclinometers, piezometers, settlement monitoring, and vibration measurements. Also includes ground improvement recommendations.

Home Inspections

Independent geotechnical evaluations for homeowners, real estate professionals, and property investors. We evaluate foundation performance by analyzing wall cracks and visible signs of structural movement or soil-related issues, including expansive clays. Reports are clear, concise, and written in plain language with practical recommendations.
