Geosciences & Civil Engineering

DiGioia Gray has geotechnical engineers and geologists that are highly experienced in the principles of engineering geology, hydrogeology, soil and rock mechanics, subsidence remediation, landslides, and mine fire investigations. We coordinate drilling services, soil and rock laboratory testing and field testing. We also monitor field investigations and provide slope-stability analyses, foundation design, topographic and geologic mapping, grading plans and cost estimates for site development.

Landslide repairing

DiGioia Gray specializes in foundation design and analysis for all types of shallow and deep foundations, using the latest design methods. Due to our extensive experience and collaborative research efforts on foundations we have become the foundation consultant of choice for many challenging projects. In addition, we have an exclusive relationship with the Electric Power Research Institute that allows DiGioia Gray to license and make technical modifications to the FAD Tools software package - a design and analysis tool for various types of deep foundations.
