Forensic investigations of subsurface (geotechnical/geological) incidents can be complex. Though certain damages may be viewed from the surface, there are times that the primary problem resides in the subsurface. YAES professionals are experienced at assessing damages to structures and their foundations resulting from subsurface conditions including sinkhole activity, shrink/swell (expansive) clays, slope movement (landslides), collapsible soils, organic soils, hydro-fracking, and mining or landfill activity.
YAES also performs geotechnical investigations of related fields such as hydrology (surface water/erosion) and geohydrology (groundwater).
Our phased and multidisciplinary approach to the investigation of ground movement, damages and subsurface conditions provides an efficient means to the determination of cause as well as a cost-efficient determination of remediation and repair.
