Subsurface Investigation

DLZ provides geotechnical drilling services for a wide range of structures such as high-rise office buildings, hotels, hospitals, wastewater treatment plants, and shopping centers. We have conducted explorations for a wide variety of projects. DLZ’s geotechnical engineering capabilities are complemented by our in-house subsurface investigation and materials testing laboratory. We have provided quality subsurface investigation and drilling services since 1980. Our subsurface investigation capabilities include truck, all-terrain vehicle (ATV), and barge drilling. DLZ crews are experienced in soil and rock sampling as well as instrumentation installations. Our materials laboratory is equipped to perform general index tests, consolidation tests, permeability tests, and shear strength tests on both soil and rock samples.

DLZ geotechnical engineers provide geotechnical support to other DLZ projects as well as stand-alone geotechnical assignments.
