MPBX \u2013 Multipoint Borehole Extensometers<\/a>, 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.<\/p>\n\n\n\nA 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.<\/p>\n\n\n\n
Sisgeo extensometers support tunnel convergence monitoring. These systems track EDZ development and deformation around excavations. Measurements provide essential information for excavation support and safety.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
On slopes, extensometers identify active deformation zones. Measurements follow the evolution of potential instability. Continuous monitoring enables timely and targeted interventions.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
