Monitoring of Bundeswehr Infrastructure
Sensor-based Monitoring of Critical Bundeswehr Infrastructure with Infrasolute
The Bundeswehr faces the challenge of modernizing its critical infrastructure and facilities – from bunkers and depots to command centers – and protecting them against failures and unauthorized access. Modern IoT sensor technology such as the solutions from Infrasolute offers a decisive advantage: it enables asset preservation, security, and sustainability through IoT-based early damage detection. As part of the Bundeswehr’s modernization and enhancement action plan, the use of such sensors can help reinforce existing structures and intelligently equip new buildings, enabling early response to changes and avoiding high consequential costs.
Modernization with IoT Sensors: Early Warning System for Structures
Infrasolute is a specialist in sensor-based monitoring of concrete structures, infrastructure, and civil engineering constructions. The sensor solutions make it possible to visualize the condition of structures in real time – independent of local infrastructure thanks to modern cellular standards such as LTE-M and NB-IoT. This is a major advantage, especially for the Bundeswehr, which often operates remote or heavily secured facilities. Whether new construction or existing buildings, continuous monitoring or temporary measurement – the monitoring system helps minimize risks, control costs, and extend the service life of structures in a targeted manner. By retrofitting existing facilities with wireless sensors and equipping new buildings at the factory, an early warning system is created that detects damage before it becomes a hazard.
Structural Monitoring of Bunkers and Protective Structures
Especially bunkers, shelters, and other massive structures of the Bundeswehr benefit from continuous structural monitoring. Moisture and corrosion are among the most important factors that, in combination with environmental influences, cause invisible damage inside reinforced concrete structures. If, for example, corroding reinforcement steel remains undetected, it can eventually compromise load-bearing capacity – making repairs very costly. This is where Infrasolute sensors (e.g., CorroDec 2G) come into play: they detect corrosion activity and moisture within the concrete, enabling early countermeasures to be taken. The sensors operate wirelessly and energy-autonomously and can be installed in existing structures with minimal effort (retrofittable) – for example, via core drilling into bunker walls. Typical application areas include all types of concrete structures, including hydraulic structures, bridges, parking garages, or shaft structures – with similar requirements to many military protective buildings.
The wireless remote querying of measurement points allows the condition of critical building structures to be checked at any time. This provides the Bundeswehr with valuable information about the condition of the structure and enables timely, targeted action before cracks, spalling, or concrete degradation become visible. In this way, the substance and value of the facility are sustainably preserved, and repair measures can be planned proactively and cost-efficiently. Especially during the renovation of older bunkers, the sensor technology enables real-time condition assessment and monitoring of the renovation’s success (e.g., drying of masonry or halting of corrosion).
Crack and Vibration Monitoring for Structural Safety
Military facilities are sometimes exposed to vibrational stress – whether due to training detonations, the operation of heavy vehicles, or external influences. Infrasolute offers sensors for crack monitoring and static changes that comprehensively record such impacts on structures. Crack sensors measure changes in crack width in masonry or concrete and trigger an alarm as soon as defined thresholds are exceeded. This way, the responsible personnel are automatically alerted if, for example, existing cracks begin to widen, allowing for immediate intervention.
A typical application is the monitoring of ammunition depots or bunker facilities located near detonation sites: if vibrations occur due to explosions, the sensor system can detect structural changes in real time and report whether the structural integrity remains intact. The data is transmitted reliably and energy-efficiently via NB-IoT, ensuring connectivity even over long distances or within fortified areas. Since the sensors operate wirelessly and have internal memory, no complex cabling is required – making them ideal for retrofitting existing structures. Infrasolute crack sensors have been rated as extremely reliable and precise in numerous applications, making them perfectly suited for structural safety in military facilities.
Roof and Structural Monitoring in Halls and New Buildings
Not only underground structures but also large-scale roof constructions and halls of the Bundeswehr benefit from sensor monitoring. Climatic influences such as storms, heavy snowfall, heavy rainfall, or temperature fluctuations can lead to dangerous loads on wide-span roofs. For example, in aircraft hangars, vehicle halls, or warehouses, structural sensor systems enable continuous monitoring of deflections and deformations. Even the smallest unwanted movements or deflections in beams and supports are detected. If deformations exceed defined thresholds, the system automatically triggers an alert – even before structural integrity is acutely at risk.
This type of precise inclination and deformation measurement provides an important early warning system for the structural integrity of large buildings. Especially in the construction of new military infrastructure, sensor technology can be integrated from the outset to monitor operational loads (e.g., observing settlement of a new protective structure over the first years). But even in existing buildings – such as older depot halls – roof monitoring can be retrofitted, as Infrasolute components operate completely wirelessly and battery-powered. This eliminates the need for wiring in sensitive areas, and the sensors meet the highest standards even in outdoor environments (fully sealed and weather-resistant). Proactive alerting thus protects against unexpected structural failures and supports decision-making on, for example, when a roof must be cleared of snow or reinforced.
Keeping an Eye on Water Levels, Climate, and Infrastructure Data
In addition to structural monitoring, environmental and operational parameters also play a major role in military facilities. Infrasolute offers universal wireless sensor systems that can detect and report a wide range of measurements. These include water levels, temperatures, meter readings, pressures, access activities, and more, all of which can be monitored in real time via NB-IoT. Wireless water level monitoring is particularly important in pump shafts of bunkers or barracks to detect rising groundwater or flooding at an early stage. Instead of relying on labor-intensive manual inspections, the sensors automatically report the water level in shafts or tanks, even if these are difficult to access. This way, in the event of an emergency (e.g., flooding), an alert can be triggered immediately and countermeasures (pumping, sealing) can be initiated in time.
Also relevant is the monitoring of indoor climate in sensitive areas. In ammunition depots or IT control centers of the Bundeswehr, temperature and humidity often need to be maintained within narrow tolerances. Wireless sensors can continuously measure the climate and environmental conditions around the clock. In the event of deviations – such as rising humidity that could destabilize explosives, or excessive temperatures in server rooms – an alarm is triggered automatically. Fill levels of fuel or water tanks can also be detected using level sensors, simplifying logistics and supply security. Thanks to their robust, sealed design, the devices function even under extreme conditions (e.g., outdoor facilities, frost, or heat) and are long-term stable with minimal maintenance. The collected data flows into a central monitoring software or the existing control system, where it is analyzed and archived. This allows the Bundeswehr to maintain full oversight of all critical infrastructure parameters and operate its facilities optimally.
Sabotage and Access Monitoring of Sensitive Areas
In addition to protection against natural or wear-related hazards, security against sabotage and unauthorized access is also essential – especially for military facilities. Infrasolute offers specialized sensor solutions for this purpose, such as for the monitoring of access doors, hatches, and shafts. Security-critical infrastructure requires special safeguarding measures – Infrasolute solutions prevent unauthorized opening, intrusion, and vandalism. Specifically, this means: at a heavy bunker door, an access hatch, or, for example, an ammunition chamber gate, a sensor can be installed that reports the “open/closed” status in real time. If the protected door is opened or tampered with without authorization (attempted sabotage), the system immediately detects this and triggers an alarm.
One example is the monitoring of recessed shafts (cable shafts, utility shafts) on military training grounds or barracks premises. These typically remain closed and secured – if a cover is lifted, the sensor detects this immediately. Thanks to energy-efficient battery power and wireless technology, the sensor can be flexibly placed in the shaft cover or door frame and operated over long periods. Such a system is often connected to a gateway that can also integrate other sensors (e.g., crack or water level detectors) in the surrounding area. This provides the Bundeswehr with a comprehensive security system that immediately detects acts of sabotage or break-in attempts. It significantly increases the security of, for example, weapon and ammunition depots, communication facilities, or secured operation rooms, as response forces can be alerted early, before any major damage occurs.
