Geotechnical Testing

Advanced geotechnical testing for deep foundations, soil behavior, and in‑situ deformation.

Geotechnical testing is a critical component of understanding how soil, rock, and structural elements behave under real‑world loading conditions. Our geotechnical testing services provide engineers, designers, and contractors with the high‑quality data required to evaluate ground performance, verify design assumptions, and ensure the long‑term stability of foundations and underground structures. Whether a project involves deep foundations, complex soil–structure interaction, or challenging subsurface conditions, our geotechnical testing solutions deliver precise, repeatable measurements that support confident decision‑making throughout the construction process.

Sixense offers a comprehensive suite of geotechnical testing tools capable of addressing a wide range of project requirements, from load and pull‑out testing to in‑situ deformation measurements and borehole deviation analysis. Every geotechnical testing program is carried out using rigorously selected instrumentation, installed and operated by experienced specialists who understand the importance of accuracy, traceability, and adherence to international standards. Because many geotechnical tests are costly and difficult to repeat, we place exceptional emphasis on proper setup, calibration, and data validation to ensure that each test produces reliable, actionable results.

Our Solutions for Measuring Geotechnical Parameters

Load and Pull‑Out Tests

We perform a full range of geotechnical testing on piles, micropiles, bars, nails, tie rods, and bolts under tension, compression, and horizontal loading. These tests validate the physical and mechanical behavior of structural elements under real conditions. All procedures follow standardized methodologies, typically ASTM D1143 (Deep Foundation Static Compressive Load), ASTM D4435 (Rock Bolt Anchor), ASTM E488 (Concrete Anchors), ASTM E1512 (Bonded Anchors), or similar.

Our teams handle the complete process, from installing instrumentation to operating it during the test, and can provide full test management when required. Because load tests are expensive and often impossible to repeat, the selection, installation, and configuration of instrumentation must be executed with exceptional care. Our geotechnical testing specialists ensure that every detail is controlled to deliver accurate, defensible results.

Plate Tests in Galleries or Shafts: Measuring the Deformation Modulus of Rock and Soil

Also known as the rigid plate jack test, this geotechnical testing method determines the in‑situ deformation modulus and Poisson’s ratio of rock or soil masses. A steel plate is pressed into the ground using a hydraulic jack, with reaction forces typically taken from the opposite wall of the gallery or shaft.

During the test, incremental loads are applied to the plate, and deformation is measured using comparators and, when required, mini‑drilling extensometers installed beneath the plate. By comparing applied loads with measured settlement or deformation, engineers can calculate the stiffness and deformation characteristics of the material. This information is essential for evaluating ground stability and optimizing foundation design.

SixGyro: Drilling Deviation Measurements

As part of our geotechnical testing capabilities, we offer SixGyro, a gyroscopic probe designed to measure borehole deviation at any depth and in any orientation. The system includes centralizers that allow measurements in boreholes of virtually any diameter. Because the probe is immune to magnetic interference, it can be used in open holes, cased holes, and metal drill pipes.

SixGyro provides accurate, reliable deviation data that supports drilling operations, directional control, and quality assurance for subsurface construction.
