With the installation of emvau-schlacke on the site of the Burchardkai container terminal, this building material has demonstrated its suitability as a base layer even under particularly high loads. The ash was able to meet the high load capacity requirements of 180 MN/m2, which are necessary due to the heavy container traffic, without any problems. By using emvau-schlacke, the material costs for the base layer can be up to 40% lower than for conventional building materials.
