Dams and levees

Monitoring of your hydraulic structures (dam, dike, etc.)

Cementys offers innovative and sustainable solutions for the monitoring and expertise of aging hydraulic structures in their environment.


      • Precise geodetic and topographic measurements for monitoring deformation of structures and the surrounding environment :

        • INSAR, GNSS, Total Stations (manual measurement campaigns or automated monitoring), Leveling, Terrestrial radar, Photogrammetry, 3D scanner, bathymetric survey.
      • Automated monitoring systems specially designed for hydraulic works :
        • Drowning or facing extensometers, flowmeters, piezometers and pore pressure cells, total pressure cells, direct and reverse pendulums, multi-point extensometers and inclinometers in drilling, facing tiltmeters, vinchon and fissurometers, pressure cell, hydraulic tassometer, etc.
        • Robust and durable acquisition centers.
        • Vibrating strings, optical fibers, and electronic technologies.
      • Automated monitoring systems for monitoring environmental parameters :
        • Weather stations (solar radiation, wind speed, rainfall, air temperature, etc.), level gauges, temperature gauges, etc.
      • Distributed measurement systems (temperature, deformation and acoustics) by optical fibers for monitoring dikes and dams :
        • DTS, DSS and DAS.
        • Geo-Detection of leaks and landslides.
      • Geotechnical and géophysical investigations :
        • Drilling for laying geotechnical instruments.
        • Core or destructive drilling with recording of parameters.
        • In-situ geotechnical and hydrological tests (pressuremeter, penetrometer, dilatometer, Lugeon, Lefranc, Micro-reel, etc.).
        • Study of water and soil pollution.
        • Laboratory tests on samples.
        • Geophysical measurements (georadar, parallel seismic, electrical panel, etc.).
      • Concrete expertise (diagnosis of pathologies, measurement of sustainability indicators, in situ stress measurement on dams, mechanical and chemical tests in the laboratory).
      • In-depth Technical Visits and underwater inspections.
      • Data management and interpretation :
        • Data storage and visualization web platform with GIS.
        • BIM or EF digital model (digital twin) with auscultation data taken into account.
        • Cell of data managers specialized in dams.
        • Statistical analysis of monitoring data (HST, Delay effects, Machine Learning, etc).
        • Risk mapping tool for a fleet of hydraulic structures.
        • Predictive or conditional maintenance models and decision support algorithms.
      • Assistance to the Contracting Authority (monitoring, diagnosis, prognosis, work scheduling).
