Stable Ground In-Situ, LLC

Advanced field investigation methodologies designed to measure geotechnical parameters directly in the ground, providing high-resolution subgrade data for foundation design.

• Cone Penetration Testing (CPT)

  Provides a fast and efficient view of subgrade soils at very short intervals to enhance characterization and parameters.

• Plate Dilatometer Testing (DMT)

  Provides a true elastic modulus of the soil at user-defined intervals, particularly useful in soft soils and when lateral characteristics are required.

• Pressuremeter Testing (PMT)

  Provides an accurate modulus of subgrade materials, applicable to dense soils and soft rock where other in-situ methods cannot advance to deeper depths.

• Vane Shear Testing (VST)

  Provides an accurate measure of undrained shear strength of fine-grained soils and soft clays, allowing both residual and remolded values to be determined at the same location.

• Dissipation Testing (CPT/DMT)

  Provides accurate coefficient of consolidation correlations to help determine overall settlement times and groundwater levels.

• In-Place California Bearing Ratio Testing (CBR)

  Allows strength testing of pavement subgrades or bases digitally in the field state without requiring laboratory testing.

• Wave Velocity Analysis (Vs and Vp)

  Enables correlations between dynamic engineering properties and reduction of IBC Seismic Site Classification.

Comprehensive processing of field-collected datasets to deliver actionable geotechnical parameters and engineering recommendations.

• Foundation Bearing Capacity Analysis

  Evaluates soil loading capacities to optimize foundation designs and reduce construction costs.

• Soil Settlement Estimation

  Determines expected deformation and settlement times to ensure long-term structural stability.

• Seismic Site Classification

  Uses wave velocity measurements to determine building code site classifications and support dynamic analysis.

Specialized advisory services to assist engineering and construction teams with complex geotechnical challenges.

• Ground Improvement Verification

  Applies advanced testing methodologies to verify soil strengthening during and after ground improvement operations.

• Traveling Testing Services

  Provides mobilization of specialized testing equipment and operational expertise to project sites nationwide, utilizing client-provided rigs when necessary.
