gräfix - Building materials for walls and floors

The good prevails

gräfix: Biological building materials for walls and floors. Gräfenberg is located in the northern Franconian Alb, at the southern entrance to "Franconian Switzerland", and thus at the north-eastern end of the large Jurassic range, which continues from France via the Swiss Jura and the Swabian Alb to the Franconian Jura. Gräfenberg lies in the area of the White Jurassic with the typical "banked limestones", which formed in the Jurassic Sea around 155 million years ago. In the White Jurassic, limestones were formed by precipitation of calcite from the seawater and from the fragments of calcareous hard parts of organisms that died in the sea, such as corals, mussels, calcareous sponges, sea urchins and brachiopods.

We extract this high-quality and valuable raw material in a selective mining process, for use in a wide range of applications and for further processing.

Good things prevail

All products are ecological and sustainable.

A holistic view of the company's processes starts with the development of new products and ideas.

As a medium-sized company, it has been our maxim for many years not only to extract and refine raw materials, but also to think about ecological and sustainable utilisation and recycling. Similarly, as a small manufacturer, innovation and customer service are of fundamental importance to us and are "lived" by our team, but also to set us apart from our large competitors.

Another step in the right direction

Administration in Gräfenberg

With the relocation of the administration to our main production site in Gräfenberg, a long-planned wish has been fulfilled. A contemporary and technically modern building was integrated into the neighbourhood parallel to the B2. Equipped with a spacious showroom and the corresponding exhibits, our customer can inform himself optimally. Various training and conference rooms can be used optimally and mutimedially for meetings, training courses and seminars.

Lime - the building block of life

Lime is not only an important building block of life, it is also the fifth most common element on earth. Lime was already present in prehistoric times around 2 billion years ago. However, it was the Jurassic period, with its diversity of species and plants, that brought about the largest proportion of today's raw material deposits. An interplay of deposition and erosion of rock layers over millions of years led to the formation of the Franconian Jurassic limestone, among other things. Tectonic shifts and the retreat of the shallow sea left behind a charming and unique landscape with some bizarre rock formations and a large number of embedded ammonites. For this reason, we grant fossil collectors access to collect fossils on two fixed days a year.

The oldest limestone kilns to date were found in what is now Iraq and are estimated to date back to around 2500 BC. A complex and energy-intensive extraction and production process that was only made easier with industrialisation. Thanks to the wealth of possible applications, lime found its way into all areas of daily life. In construction in particular, the reproducible and qualitative advantages could be utilised by burning the limestone in modern kilns, slaking and grinding it in the factory and then packaging it as a powder material. A further step towards sustainability and efficiency is to selectively allocate the raw material before it is extracted. A measure that saves resources and has a positive impact on quality prior to production and refinement.

 

Ready-mixed dry mortar has many advantages

Functioning quality assurance and an existing liability management system

The invention of ready-mixed dry mortar was a ground-breaking development in the preparation and realisation of planned construction projects. With the development of formulas, production processes could be controlled. Products were now reproducible and the ingredients of the recipe could be harmonised and finely dosed. A completely different quality management and solid quality assurance for the construction work could now be achieved.

Almost 90 years later, ready-mixed dry mortar is still on its triumphal march. Packaged in sacks, film or buckets, as well as loose in silos, the quality and above all the logistical advantages are absolutely unbeatable. Furthermore, there is an increasing call for harmonised products, as well as the question of product liability according to the specified parameters in our increasingly regulated processes.
