Bethmannstraße 50-54, Frankfurt am Main

Between September 2025 and January 2026, we carried out concrete repair works at Bethmannstraße 50–54 in Frankfurt am Main on behalf of Lang & Cie. Management GmbH & Co. KG. Covering a total area of approximately 11,000 m², the works included the application of concrete replacement mortar to ceilings, columns and beams using the wet-mix spraying method to increase the required concrete cover. A particular feature of the project was the continuous and dust-free supply of dry mortar directly from the silo to the wet-mix mortar continuous mixer. The fully automated mixing process enabled particularly efficient spray application with minimal rebound.
