The Leier Group of Companies is an internationally recognised corporation with a total staff of approximately 2,000 at 40 sites in Austria, Croatia, Hungary, Poland, Romania and Slovakia. Leier’s business activities are well diversified but can be separated into two main sectors: construction materials and services. The construction materials’ area concerns mainly concrete products – from large-scale precast components right up to paving blocks that Leier produces and markets in the above-named countries. A total of 15 concrete paving block and precast production facilities provide the potential for market-driven manufacturing in such a large sales area. Of paramount importance to Leier is not the quantity of concrete products manufactured but rather their quality, with a view to maintaining customer satisfaction on a long-term basis. In order to keep up with customer demand for antiqued concrete pavers – and increasingly for multi-format blocks -, a new ageing plant with a fully automated sorting and packaging unit was commissioned at the production facility of Kaiserstein, a member of the Leier Group of Companies. The plant was supplied by Gerhard Warning GmbH from Bielefeld, Germany.
