HDL’s Geotechnical Services Group brings wide ranging expertise to assist clients with soil and groundwater challenges. We provide out-of-the-box solutions and have successfully used multiple techniques to solve geotechnical challenges throughout the State.

We pioneered the use of dynamic compaction and large-diameter helical piers in frozen soils for wind turbine foundations in Alaska. We routinely develop design solutions keeping in mind future climate changes and how these changes may impact the design life of structures. We address challenges with a pragmatic and practical approach to assure our clients receive exceptional value.
