Bergmann Kalk has been successfully mining in Azendorf for almost 110 years, and is now owned by the Groppweis family in the fourth generation. Our high-quality natural limestone, which is the raw material for a large number of different lime-based applications, is extracted from the quarries close to the works in open-cast mining. State-of-the-art, computer-controlled plant technology – with the most modern PFR lime kiln in Europe – together with an experienced team of employees ensure the quality of our premium products.
A reliable and fluent production process – from the blasting to the finished product – guarantees the punctual delivery of our products to our customers. The constant control of the individual production steps by our in-house laboratory ensures the consistent quality of the products.
Our mission statement is characterized by sustainability and internationality. Bergmann Kalk is a traditional medium-sized company that takes responsibility for its employees and the region. We think in generations instead of financial quarters. This philosophy is reflected in our resource-conserving approach to natural raw materials, as they are the basis of our natural products.
Quality is the basis of our entrepreneurial success. That is why the needs and wishes of our international customers have top priority for us. We meet this demand with our reliable products, our services, our competent advice, and our smooth and punctual order processing. In this way, we ensure our customers’ orders are secure, and thus corporate earnings and jobs.
Occupational safety and environmental protection are central elements of our corporate policy. This can be seen in our introduction of an integrated management system.
The certified quality management system, in accordance with DIN EN ISO 9001/2000, was introduced as long ago as 2005, and is based on the principles formulated in our corporate policy. In our quality concept, both the quality of the product and the quality of our employees’ teamwork – as well as the relationship with our customers – adhere to the same high standards. The achievement of customers’ satisfaction through consistent delivery of products that meet customer requirements, are of impeccable quality, and are not only reliable but also good value for money, is what we consider key to the long-term success of the company.
Our QM system is aimed at continuously improving the quality of our products and services, and adapting them to the technical and economic requirements of our customers, with the aim of achieving the greatest possible customer satisfaction.
We place particularly high demands on the production of our straight feeding stuffs. A hazard analysis and the monitoring procedure, in accordance to the HACCP concept, ensure that all feed produced in our company complies with the legal requirements, guaranteeing customer satisfaction.
Furthermore, in 2005, we received certification of compliance with QS criteria in the meat production chain (in the stage ‘single feed producer’ in the context of the QS food inspection system). In 2008, this was extended to ‘road transport (animal feed)’ in accordance with the GMP standard.
Research and Development
Together with Franken Maxit, a new research and development center was built on the factory premises in Azendorf. In addition to the continuous further development of dry mortar products, ways of optimizing lime production are also being researched here. The formulation of lime mixtures on behalf of customers is also carried out in the modern production complex.
The new company laboratory for the control of lime products has also been set up on the premises. Close monitoring is a prerequisite for the manufacture of high-quality products: In addition to continuous production control, every customer delivery is also checked before leaving the factory premises.
The company laboratory is equipped with state-of-the-art laboratory equipment. This enables us to offer a wide range of analyses to our customers.
Environment and Sustainability
The companies Johann Bergmann GmbH & Co. and Franken Maxit Mauermörtel GmbH & Co. have committed themselves to continuously reducing energy consumption and to improve both energy efficiency and energy use. In order to achieve this goal, we have introduced an energy management system according to DIN EN ISO 50001/2015. We ensure that all the requirements of this standard are correctly implemented and that the processes within this energy management system are constantly improved. In doing so, we also commit ourselves to ensuring the availability of information and the necessary resources to achieve our strategic and operational goals, and to comply with all applicable legal requirements regarding energy-related performance.
In addition, we regularly check whether
- the necessary financial and structural conditions are in place
- all employees are integrated into the implementation and execution of the management systems
- the improvement of energy-related performance is supported by the purchase of energy-efficient products and servicesthe energy policy within the organization is documented and communicated across all levels, and is regularly reviewed and updated as necessary
“Our particular strength lies in the high technical standard that we have achieved. The density of our locations in Germany and the Czech Republic and our international orientation also play a decisive role. This enables us to reach every customer in the shortest possible time and guarantee a constant readiness to deliver,” says Sebastian Groppweis, Managing Director of Bergmann Kalk, which co-founded the maxit Group.

Lime mining has a tradition of more than 110 years in Azendorf. As early as 1908 the company founder Johann Bergmann, grandfather and great-grandfather of the current shareholders Hans-Dieter and Sebastian Groppweis, respectively, built a lime kiln in the Azendorf district of the municipality of Kasendorf, thus laying the foundation for the successful development of the company. The burnt lime was used by construction companies as building lime for bricklaying and plastering, as well as in agriculture in the surrounding area as fertilized lime. The term ‘immediate surroundings’ was used at the time to refer to a maximum distance of 30 km around the Azendorf plant.
