Geotechnology is providing drilling, Cone Penetrometer Testing (CPT), and sampling at Prairie Du Pont and Fish Lake Levee Systems using hollow stem augers, mud rotary and wireline coring techniques. Disturbed and undisturbed samples were obtained in general accordance with ASTM standards. Additionally, the automatic standard penetration test hammers on each of our machines were calibrated in the field during the project. CPT was performed at 330-foot intervals on the levee riverside toe. Coordinated submittal results were sent to the Army Corps of Engineers – St. Louis District for analysis of slope stability and exit gradient
