Geotechnical Engineering and Testing

Geotechnical Engineering & Testing

Combining our experience and expertise with our field and in-house laboratory resources allows SME to provide a wide variety of geotechnical services

Whether a project requires closing a landfill, stabilizing a highway embankment, or armoring a shoreline, our team can handle the process from beginning-to-end. SME provides subsurface investigation, geotechnical design, interaction with agencies for regulatory approvals, preparation of construction plans and specifications, inspection of work product, QA/QC testing of soil and geosynthetic materials, and construction documentation.

SME’s geotechnical engineers conduct subsurface investigations leading to practical solutions for even the most challenging projects. This includes services for support of above-ground structures; designs for control of subsurface water forces and drainage; design of soil and geosynthetic barrier systems for lining and covering waste disposal sites; and design of filtering media to resist internal erosion of soils subjected to subsurface seepage. We also evaluate slope stability and settlement for dams, waste deposits, and other earth and earth-supported structures.

SME conducts inspections of water storage dams, landfills, and liquid storage lagoons to evaluate hydraulic performance and structural integrity. The geotechnical staff designs and installs below ground instrumentation to monitor soil and groundwater behavior relative to potential adverse effects on surface and subsurface infrastructure.

We also provide engineering inspections and evaluations of levee flood control systems for accreditation by the Federal Emergency Management Agency (FEMA).

In-House Geotechnical Testing Lab

For over 35 years, SME has maintained an in-house geotechnical laboratory for physical and mechanical property evaluation for a wide range of material types, including soil, sludge, ash, and sediment. The lab gives our engineers fast access to a wide range of standard geotechnical tests for characterizing soil and soil-like materials for use in development and/or re-development of raw land and commercial or industrial sites

The laboratory also provides outside consulting engineering firms and government agencies with reliable, high-quality, on-time test results.
