The total length of supra-local roads in Germany is around 230,000 kilometers (as of 2019). This includes highways, national roads, state roads and district roads. Crash barriers are not present everywhere, but the total length is nevertheless immense.
The crash-barrier systems used in Germany are made from bolted steel sections or prefabricated reinforced-concrete elements. The service life is assumed to be 25 years. This means that many kilometers of crash barriers are renewed every year. The production of crash barriers made from steel or reinforced concrete requires a large amount of energy and releases considerable quantities of carbon dioxide (CO2).
The deployment of wooden crash-barrier systems is an efficient means of improving the eco-balance of the construction sector. They can be manufactured using comparatively little energy and store CO2 for a long period of time.
From a global perspective, there are already a handful of systems which are made entirely or partially from wood. These have, however, various system-specific disadvantages, including a still-high steel proportion, the use of tropical hardwood, very elaborate construction, and incompatibility with established systems.
By developing a compatible crash-barrier system made from indigenous woods, we aim to create a consistently sustainable solution with high market potential.
