We developed the ROCKFALL-X G and ROCKFALL-X A damping system with the aim of increasing the level of protection and durability that rockfall protection galleries provide. Equipped with cellular glass ballasts or used tires respectively, this system enhances energy absorption capacity while simultaneously reducing the static loading associated with conventional gallery reinforcement solutions. The modular system's low weight reduces the static load on the gallery and facilitates not only easy installation, but also reduces maintenance work after a rockfall incident. The ROCKFALL-X A damping system is also suitable as a temporary protection measure during construction works.
