Build Confidently
Our goal is to provide more accurate soil data to create a safer, faster, and more efficient engineering design.
Stable Ground In-Situ
Where We Build Your Visions
Stable Ground In-Situ, LLC (SGI) is a geotechnical firm focused on providing advanced, accurate and timely in-situ soil testing services to aid in your engineering design. Services include Cone Penetration Testing (CPT), Flat Plate Dilatometer Testing (DMT), In-Place California Bearing Ratio Testing (CBR), Pressuremeter Testing (PMT) and Vane Shear Testing (VST). In addition to field services, SGI’s experienced Engineers are available for data analysis and general engineering consulting.
For most any structure, SGI’s Engineers can implement our services before construction to optimize soil parameters, reduce foundation costs or pave the way for a more economical design altogether. These same methodologies can be used for verification during and after ground improvement operations.

Who our clients are
SGI’s target client is a civil engineering, geotechnical engineering, or construction firm that requires a more specialized soil investigation or an alternate approach to geotechnical obstacles. Specifically, SGI specializes in CPT, DMT, CBR, PMT and VST for use in bearing capacity, settlement, and stability analysis. The above testing expedites analysis, is less conservative, and generally creates significant cost savings for the client.
