With decades of experience in seismic protection, Freyssinet delivers innovative solutions through its ISOSISM® line—an established name in structural safety. Our tailored products and technical support help ensure the resilience of new buildings in earthquake-prone regions.
ISOSISM® systems are designed for a wide variety of uses from new construction to retrofitting and post-earthquake repairs. They’re ideal for bridges, viaducts, industrial sites, energy infrastructure, heritage buildings, hospitals, and schools.
Our technology is built on four core principles that can be used individually or in combination: seismic isolation, energy dissipation, structural connection, and movement accommodation.
Projects using ISOSISM® typically see up to 15% in initial cost savings. Plus, structures remain operational after seismic events, reducing downtime and reconstruction expenses.
By reducing the demands on superstructures and foundations, our systems contribute to more resource-efficient and environmentally conscious construction.
ISOSISM® devices are easy to install, replace, and maintain to ensure long-term reliability with minimal upkeep.
All systems meet international standards, with CE marking available upon request, ensuring compliance and peace of mind.
We don’t just deliver products—we provide tailored seismic protection strategies based on your structure’s design, location, and budget.
From initial risk assessment and structural analysis to installation and ongoing maintenance, Freyssinet offers full lifecycle support.
Our technical specialists work closely with you from the earliest stages of your project to:
This dual expertise, engineering insight and seismic risk analysis, is available to both structural designers and project owners. It enables smarter decision-making, helping to reduce overall construction costs while enhancing the resilience of infrastructure against seismic events.
We begin with a detailed evaluation of your structure’s seismic behavior using both linear spectral analysis and non-linear time history analysis. Based on the required performance criteria, we design a tailored ISOSISM® solution to meet your project’s specific needs.
To ensure precision, prototypes are developed and tested in-house at our state-of-the-art ISOLAB facility in Italy.
Our manufacturing process adheres to CE marking standards, ensuring consistent quality and compliance. To guarantee performance, up to 20% of production batches undergo rigorous testing at ISOLAB—home to some of the most advanced seismic testing equipment in Europe.
Freyssinet offers expert technical assistance during installation to ensure every ISOSISM® device is fitted according to best practices and project specifications. For a seamless experience, our teams can also manage the full installation process, including all related works.

After a seismic event, our engineers are available to inspect your protection systems, assess any damage, and recommend necessary repairs or structural reinforcements to restore full functionality.
These systems are designed to absorb and dissipate seismic energy, helping to reduce the impact of earthquakes on structures. They perform especially well under sudden stress, such as seismic shocks or vessel impacts, while allowing smooth movement during normal conditions. Damping systems can also be combined with isolation technologies like High Damping Rubber Bearings to control displacement and reduce internal stress.
Isolation systems work by increasing the structure’s fundamental vibration period. This reduces the building’s response to seismic acceleration, often cutting it by a factor of two or three, which significantly improves structural resilience.
The Shock Transmission Unit (STU) connects separate structures or creates fixed points in civil engineering projects. It activates during events like earthquakes, emergency braking of high-speed trains, or strong winds, providing added stability when needed.
The SFX joint is a supported mat joint that absorbs movement through the deformation of elastomeric components. It accommodates structural shifts while maintaining integrity and flexibility.
Freyssinet offers complete seismic protection for existing structures. From strategy development to in-house design, manufacturing, and installation, we provide turnkey solutions for retrofitting, structural reinforcement, and post-earthquake repairs.
