Geodetic and Electronic Monitoring Systems



Hydra Capsule have restructured its hydraulic jacking and monitoring division, with additional research, development and investment. Which has allowed our jacking systems, geodetic monitoring and real-time instrumentation to be completely integrated as one complete operating unit. This allow

Hydra Capsule to offer a complete “one-stop” solution for all suitable applications, allowing for complete control and analytics of structures throughout projects.

Hydra Capsule is a leading subcontractor for supplying flat jacks, hydraulic jacks for hire, temporary propping systems, electronic instrumentation, and real-time / long-distance monitoring. With over 30 years of experience within this market, Hydra Capsule has extensively designed and developed systems to suit all applications.

Currently Hydra Capsule monitoring division can offer:
  • Consultancy and Conceptual designs
  • Installation of instrumentation, monitoring equipment, temporary propping works, and hydraulic jacking systems
  • Real-time and long-distance monitoring, with the inclusion of provisional data analysis facilities
  • Complete data-logging and alarm / trigger limits integration; via SMS or email warnings, for complete monitoring control
  • Automated (solenoid control) and / or responsive solutions (manual control)
  • Integration of all electronic instrumentations (ie. Geodetic Monitoring Systems, pressure transducers, movements displacement / LVDTs, stroke sensors, tilt sensors, strain-gauges and load cells) to one control software unit to analysis
Hydra Capsule have carried out numerous projects, previously Kingston Bridge – Glasgow and Guild Hall – London (which is still installed to-date), to current projects utilizing our system:

Birmingham New Street Station Redevelopment – Hydra Capsule have installed a jacking system with ULS to over 9,000 tonnes with load monitoring through pressure transducers, load cells and strain gauges. To relative displacement monitoring of structural movements, attached to the critical elements, to measure up to accuracy of +/- 0.01mm through Geotechnic monitoring devices.

The complete system being data-logged and accessed through our wireless viewing page. The project is approx 18 to 24 months duration, prior to permanent installation works to be carried out.

Tate Modern, London Art Galley – Hydra Capsule were approached to design and install a hydraulic jacking system capable of 4,000 tonnes. The complete system, was designed and manufactured by Hydra Capsule to meet the Engineers specifications.

The hydraulic jacking system was required to be electronically controlled; single, multi-sets and/or all hydraulic jacks activated synchronously, achieved through the use of electronic non-return solenoid-control.

The monitoring element involved “real-time” monitoring during jacking phases and throughout the 12 months construction period. Monitoring the relative movement of the support beam to the structure. This was achieved by installed stroke sensors, deflection boxes, and Hydra Capsule’s relative laser levelling system. With the integration of pressure transducers to distribute loads through the correct load-path throughout the construction phases.


As stated above for each project, all the monitoring information is transferred from our on-site data-loggers to a wireless viewer website page and can be displayed and access 24/7 worldwide. In addition, Hydra Capsule software can introduce numerous specified tolerance limits, which then are exceed, will activate automated trigger alarm and distribute to all key personnel through an email or SMS text alarm indicating the location and description.

This will allow key personnel to review and analysis the information and trend data provided. To carry out the necessary works to the structure. Through change of the construction phase working or introducing of jacking adjustment, giving construction our full support.
