Sisgeo borehole extensometers measure axial ground movements with high precision.
These instruments provide reliable data for tunnels, deep excavations, embankments, slopes, and dams.
Each system supports stable and long-term subsurface deformation monitoring.

Sisgeo extensometers use dedicated anchors for different geological conditions. Proper anchor selection ensures accurate and repeatable measurements. Rods, sensors, and heads work together to detect every displacement.

Our range includes rod extensometers, MPBX – Multipoint Borehole Extensometers, sensor chains, and mobile probe solutions.
Each system fits specific project needs and accuracy requirements. Digital and wireless versions simplify data management in challenging environments.

A correct grouting process improves anchor stability in the borehole. Proper borehole backfilling reduces errors and increases data quality. Grout mix selection depends on soil type and installation conditions.

Sisgeo extensometers support tunnel convergence monitoring. These systems track EDZ development and deformation around excavations. Measurements provide essential information for excavation support and safety.

In earthworks, extensometers measure settlements and lateral movements. Collected data help evaluate soil behavior during construction stages. This information is crucial for design verification and mitigation plans.

On slopes, extensometers identify active deformation zones. Measurements follow the evolution of potential instability. Continuous monitoring enables timely and targeted interventions.

Sisgeo systems integrate with dataloggers and remote monitoring platforms. Automated data acquisition improves analytical efficiency over time. Digital solutions ensure constant control of geotechnical behaviour.

Sisgeo offers technical support for instrument selection and installation. Each project receives expert assistance and tailored solutions. Our technologies ensure reliability, precision, and continuity in monitoring.
