We offer testing tools for any project with geotechnical issues.
Our solutions to measure geotechnical parameters
Load and pull-out tests
Tests on piles, micropiles, bars, nails, tie rods and bolts, in tension, compression, horizontal loading
Our geotechnical load tests validate the real‑world performance and physical behaviour of structural elements such as piles, micropiles, anchors, nails, tie rods and bolts. These tests follow established standards, primarily the French P94 series, which is progressively being replaced by the ISO 22477 international standards for foundation and geotechnical testing.
Sixense teams handle the complete process, including instrumentation design, installation and onsite operation, and can also manage the full testing campaign when required. Because each load test is complex, costly and difficult to repeat, the selection, configuration and installation of instrumentation must be executed with exceptional precision. Our expertise ensures that every measurement is reliable, helping project teams confirm design assumptions, verify capacity and ensure the safety and long‑term performance of geotechnical structures.
Plate tests in galleries or shafts
Measurement of the deformation modulus of rocks and soils
The rigid plate jack test is used to evaluate the in‑situ deformation properties of soil and rock by applying controlled load to a steel plate. During the test, the depth and settlement of the plate are monitored, and deformation at different depths can also be measured using extensometers. The reaction force is typically provided by the opposite wall of a gallery or shaft.
Incremental loading is applied through a hydraulic jack, and at each stage, the resulting ground deformation is recorded. By comparing the applied load with the measured displacement, engineers can determine the deformation modulus, stiffness and Poisson’s ratio of the ground. These parameters are essential for understanding ground behaviour under stress.
The results provide valuable insight into ground stability, helping optimise foundation design and ensuring safer, more reliable geotechnical structures.
SixGyro
Drilling deviation measurements
The gyroscopic probe delivers accurate borehole deviation measurements at any depth and in any orientation, making it suitable for a wide range of geotechnical and drilling environments. Supplied with adaptable centralizers, the system can be used in boreholes of various diameters without compromising measurement quality.
Because the probe is not affected by magnetic interference, it functions reliably in bare or cased boreholes, as well as inside metal drill pipes—an advantage over magnetic‑based deviation tools. This ensures consistent, precise data for confirming drilling accuracy, understanding subsurface geometry and supporting geotechnical investigations or foundation design.
