We have extensive experience designing and overseeing repairs on problems involving moisture intrusion, erosion, settlement, collapsible soils, expansive soils, asphalt deterioration, concrete cracking and deterioration, groundwater issues, etc We frequently get asked the question: "What is forensic geotechnical engineering?" Forensic geotechnical engineering is an analysis of a structure in order to understand the cause of problems and/or failure. For example, we frequently get calls from homeowners that are having reoccuring drywall cracks, tile cracks, and/or stucco cracks. These reoccurring problems can be related to several factors, but our job is to determine the exact cause, design a repair, and then oversee that repair.
