Pioneer in the development of earthquake protection devices, Freyssinet offers a complete range of dedicated products and associated services marketed under the well-known ISOSISM® brand.
New structures, retrofitting of existing structures, post-earthquake repair.
Bridges and viaducts, industrial and energy facilities, heritage buildings, hospitals and schools.
Based on four concepts, used alone or combined together: Isolation – Dissipation by damping – Connection – Junction
On average, initial savings of 15% on the project overall cost. Continued operations after an earthquake and lower rebuilding costs.
Earthquake protection devices allow to considerably lighten the superstructure and the foundations of a structure.
Easy installation & replacement, low maintenance.
Conformity to all international standards, CE marking on request.
Not only products. But solutions tailored to the seismic risk, the structure, its environment and your economic constraints.
From risk and structure analysis to installation of seismic solutions and maintenance.
Our technical teams will assist you to:
We make this dual expertise available to structural designers and clients, providing them with practical solutions to optimize the overall cost of the structure and minimise the seismic risks of their infrastructure project.
Prototypes will be produced in-house and tested in our ISOLAB facility in Italy, in order to confirm the right design.
The supply chain and manufacturing are done according to CE marking requirements.
Production tests can be carried out in order to guarantee reproducible performance. For CE marking for instance, 20% of the production is tested in our ISOLAB laboratory, whose equipment is unequalled in Europe.
Freyssinet proposes on-site technical assistance to help its customer install the ISOSISM device in compliance with the rules of art and the specifications.
On request, Freyssinet teams can also manage the full installation of the seismic devices including all associated works.

Following an earthquake, Freyssinet’s technicians and engineers can inspect the seismic devices in order to assess the repair needs and propose structural repair or strengthening works.
ISOSISM® damping systems allow to dissipate part of the energy generated by an earthquake so as to minimize its impact on the structures. They are particularly effective under quick stresses (earthquakes, boat impacts, etc) and offer very low resistance to slow movements under service conditions. They can be used in combination with an isolation system, especially High Damping Rubber Bearings, to reduce structural displacement while limiting the stresses to which structures are subjected.
ISOSISM® isolation systems increase the fundamental period of vibration of the structure to be protected. They reduce the response to seismic acceleration, which is reduced by a factor of two to three.
ISOSISM® Shock Transmission Unit (STU) is used to connect buildings together, or to create a fixed point on a civil engineering structure in the event of an earthquake, emergency braking by a high-speed train or gale.
The ISOSISM® SFX joint is a supported mat joint in which movement imposed by the main structure is absorbed by deformation of the elastomeric sections.
From proposing a seismic protection strategy to delivering and installing systems designed, manufactured and tested in-house, we offer turnkey solutions for retrofit, seismic strengthening and post-earthquake repair projects of existing structures.
