Geotechnical monitoring of structures and objects

Preventing ground and structural movements

SAFIBRA’s geotechnical monitoring system based on Fiber Bragg Grating (FBG) technology, allows the evaluation of geotechnical structures, sites, and environments against the geotechnical design assumptions. It provides useful data about the performance of the ground and necessary changes to construction or engineering measures in order to reach the required stability. Thanks to this, it allows early identification of the risk of harmful processes which may occur during construction, assembly works, or while maintaining the buildings and facilities.

Request information

Geotechnical monitoring of structures and objects usually includes ground movements, structural movements, water pressures, and vibrations. It is carried out during the pre-construction, construction, post-construction, as well as in the dilapidation stages.

In many cases geomonitoring may be required by statutory authorities on large projects, particularly when your project is close to sensitive structures (e.g. heritage buildings), mudflow protection facilities, civil, public and industrial buildings, highways and railways, and built up or landslide areas.

By using geomonitoring, you can manage onsite emergency situation risk and control costs by reducing the redundancy in your design.

Fiber Bragg Grating (FBG) technology

FBG technology brings many advantages over the conventional sensing methods, such as immunity to EMI/RFI, high precision, durability, quasi distribution, absolute measurement, compact size, reduced cabling requirement, etc.

Early warning of events

The geomonitoring system is equipped with direct alarm relays for immediate notifications via email, SMS, or other communication interfaces, in case of significant and unusual events.

Comparing temperature increases

Continuous monitoring of temperature increase against deformations shows whether or not the deformations are temperature dependent.

Monitoring of rainfall deformations

Our geotechnical system monitors rainfall deformations which can show whether the deformations are affected by the amount of water in the soil and whether it can be expected that cloudbursts or long term rainfall can increase deformations.

Multifunctional measuring platform

Several FBG geotechnical sensors with different functionalities can be connected by a single fiber without signals being confused. The necessary cabling becomes considerably smaller.

Prevention of catastrophic failures

Thanks to the geotechnical monitoring you’ll be able to take appropriate action in advance and thus minimize potential damages and losses.

Measuring over long distances

The distance between the unit and geotechnical sensors can be several tens of kilometers. Therefore, you can cover a large area with one unit and a multitude of sensors.

No calibration or determining of new zero

The wavelength reflected by each FBG is modulated by the measured quantity, for example strain. The geomonitoring system measures this reflected wavelength which is an absolute parameter. Hence you can turn off or replace the geotechnical monitoring instrument without having to recalibrate it or reset the zero level.

Use of existing fiber optic network

Installation of an expensive geotechnical sensor infrastructure or availability of electrical power are not necessary, which is very economical even for a large number of monitored points.

Web interface

You will be able to manage our geotechnical monitoring system via a user friendly web interface, which also provides all necessary information about the structure, reporting, and data analysis features according to your SLA.

Reporting and data analysis

Our geomonitoring system provides all necessary reporting and data analysis features. The available level of service is according to SLA.

Customized solutions and adjustments

The geotechnical monitoring system can be modified in order to meet your project’s needs, such as the desired functionality, interoperability, etc.
