CTL | Thompson offers a wide range of geotechnical and geologic expertise for preliminary design, final design, and forensic evaluations. 


Geotechnical Engineering represents the core of CTL’s practice. Our engineers, geologists, and environmental specialists can provide geologic mapping and hazard analysis, shallow and deep foundation design, expansive soil evaluations, and groundwater investigations including de-watering studies and pump tests.


Our staff includes engineers and geologists with specific expertise in the evaluation of landslides and rockfalls, including design of remedial measures using mechanically stabilized earth, soil nailing, and tie-back structures in addition to more traditional earthwork measures. Our knowledge of local conditions will assist in maintaining continuity from design to construction.
