Impact Sentinel is a cutting-edge hazard detection system designed to monitor rockfalls, landslides, and terrain shifts in real time. Built for the rail industry, it provides early warnings using advanced sensors and smart data relays—protecting infrastructure, ensuring safety, and minimizing disruption across mountainous and high-risk areas.
What started as expertise in advanced glass surface coatings and thermal dynamics has evolved into comprehensive rockfall monitoring systems and emissivity readers trusted across Europe.
Even minor rockfall events can weaken protective barriers and cause costly downtime. The Impact Sentinel system continuously monitors low-energy impacts, helping operators move from reactive repairs to predictive maintenance across rail, road, and alpine infrastructure.
Long-Distance Communication: Rockfall Monitoring in Real Time Overview Many hazard zones—such as Rockfall & Landslides, especially in alpine or isolated regions—are difficult to reach and challenging to maintain.For these locations, reliable remote monitoring is not...
Some segments of Switzerland’s Gotthard railway corridor pass through exceptionally steep terrain where traditional protective measures are difficult—if not impossible—to install. One such section required the construction of a 90-degree vertical rockfall barrier, positioned directly above a tunnel entrance.
The goal: to stop falling debris before it could reach the tracks below. But the vertical nature of the installation introduced complex safety and logistical challenges—both during setup and ongoing maintenance.
