Our sleepers made from sulphur concrete are chemically stable and have undergone various European accreditation tests by railway infrastructure managers.
Several tests have shown that sulphur concrete is as resistant to the high dynamic load of trains as traditional concrete. For this purpose, a test track has been monitored for over 5 years. It is also less porous than classic concrete. This means that sulphur concrete is less susceptible to infiltration (e.g. water). Therefore, it is also highly resistant to chemical damage and attrition.
Due to the unique properties of the material, the sleeper can be remelted and reused at the end of its life, including all its integrated components. Sulphur concrete has thus all the advantages of a material designed for the future.
