Our subsurface investigations can also involve cone penetrometer testing (CPT), dilatometer testing (DMT), and geophysical testing such as ground penetrating radar (GPR) and electrical resistivity. If required, select soil samples from the borings will be sent to our USACE validated laboratory to perform engineering classification tests. We also have the capability to provide more complex geotechnical testing should the need arise including gradation, hydrometer, triaxial shear, direct shear, unconfined compression, one dimensional consolidation, restricted flow consolidation, permeability testing, and others. A comprehensive subsurface exploration program is essential to sufficiently characterize the ground that will support any constructed facility. The quality of the exploration program ultimately dictates the geotechnical design as well as the level of the owner’s risk associated with additional costs due to unanticipated ground conditions encountered during construction. Therefore, proper planning and

execution of the exploration program is crucial. Earth Retaining Structures and Ground Improvement

WSP geotechnical engineers have experience in both the design of new earth retaining structures and the remediation of existing ones. We are experienced with the design of both temporary and permanent wall systems such as sheetpiles, soldier piles, tie back walls, soil nail walls, and concrete retaining walls. The design of the most effective wall system is highly dependent on factors including the wall height, aesthetic requirements, foundation soil conditions, water table location, soil corrosivity, and backfill materials. We are accustomed to tailoring our site investigation to provide a thorough understanding of the site conditions important in determining the most effective earth retaining structure to meet the needs of our clients.
