In-Situ Geotechnical Testing

In-Situ Testing for Comprehensive Geotechnical Investigations

In-situ testing is a critical method in geotechnical investigations, enabling the measurement of key geotechnical parameters directly in the field. This minimizes soil and mine tailings disturbance while providing reliable data for engineering and construction projects. Legion Drilling offers industry-leading in-situ testing capabilities, including Cone Penetration Testing (CPT), Piezocone Testing (CPTu), Seismic Cone Penetration Testing (SCPTu), Marchetti Flat Dilatometer Testing (DMT), and Electrical Vane Shear Testing. These advanced systems are designed to deliver precise, real-time data for a wide range of geotechnical challenges.

Advantages of Legion Drilling’s In-Situ Testing Systems

Our in-situ testing methods provide numerous benefits that make them invaluable for geotechnical site investigations:

• Rapid data collection: High-density geotechnical data is collected quickly, saving time and resources while improving the quality of decision-making.

• Cost-effectiveness: Compared to traditional soil sampling and laboratory testing, in-situ testing is more economical while maintaining accuracy.

• Real-time data visualization: Live data streams from systems like CPTu and SCPTu enable engineers to assess site conditions immediately, optimizing project workflows.

• Enhanced reliability: By reducing uncertainties, in-situ testing improves confidence in geotechnical analysis and minimizes project risks.

Additionally, high-quality soil and tailings samples can be collected using direct push technology or other advanced sampling methods in adjacent locations to complement in-situ testing results.

Cone Penetration Testing (CPT) and Variants

Legion Drilling specializes in CPT, CPTu, and SCPTu, which are essential for evaluating soil stratigraphy, groundwater pressure, and seismic site characterization. These methods are ideal for assessing soft soils, mine tailings, and other challenging conditions. Our CPTu systems integrate piezometers to measure pore water pressure, while SCPTu provides seismic wave velocity profiles for dynamic soil properties.

Flat Dilatometer Testing (DMT)

The Marchetti Flat Dilatometer Test (DMT) is a versatile tool for determining soil strength, stiffness, and consolidation characteristics. DMT results help engineers design foundations, retaining structures, and earthworks with higher precision.

Electrical Vane Shear Testing

For direct assessment of undrained shear strength in cohesive soils, Legion Drilling offers Electrical Vane Shear Testing, which delivers accurate results for stability analysis in critical infrastructure projects such as dams, embankments, and tailings storage facilities.

Sonic Drilling and Geotechnical Sampling

Legion Drilling has expanded its capabilities by incorporating Sonic drilling rigs into our fleet. Sonic drilling offers highly efficient, clean, and precise sample recovery across a wide variety of soil and rock types. Combined with our in-situ testing systems, this allows us to provide comprehensive solutions tailored to each project's geotechnical requirements.
