Guaranteed Quality
Highest Quality Natural Stone Materials
Our granite has special hardness (Sz 13,5 - 16,5), very low water absorbtion (< 1%) and extremly high abrasion resistance (min. PSV 55 - PSV 59), which is unique for the area of the Bavarian Forrest.
Best Workmanship
We refine the natural qualities of our materials in various working processes to high end natural stone products. Continuous internal and external controls guarantee that our products meet constantly the highest requirements.
Our Quality Control System verifies products specifications such as:
- Size
- Hardness and Abrasiveness
- Purity of the material
- Splitting value
- Resistance to frost
- Water absorbtion
- Resistance to polishing
- Shape of grain
Independent institutes such as the Technische Universität (TUM) MPA Bau in Munich or the LGA Bautechnik GmbH in Nuremberg conduct regular checks for ongoing quality assurance. Test certificates for our materials are available on request.
Our quality management is not reduced to product tests only but verifies continuously our productions process to improve the quality level of our products and services. Thus quality of service includes also the careful interaction with our environment: We make sure to use only state of the art equipment and machines with low energy consumption and low emissions. Our refining plants are all equipped with dust collection systems and insulated for noise reduction. The irrigation of our quarry sites reduces additional emissions of dust.
