About usMining with a long tradition and a sense of responsibility
PORR Group websiteFounded in 1881, we extract dolomite rock from the Josef Tunnel in Wellen on the Upper Moselle via underground mining and process it in surface facilities into high-quality crushed stone, gravel, grit and stone powder. We supply our products to partners throughout Europe.
We fill the voids created by mining in the Josef Tunnel with backfill materials, thereby ensuring the long-term stability of the rock mass. In doing so, we work closely with local authorities and always act in accordance with the Backfill Regulations.
Our own shipping terminal on the Moselle enables the environmentally friendly transport of materials – not only to the surrounding regions of Germany and Luxembourg, but also to France, Belgium and the Netherlands. In January 2012, the PORR Group acquired TKDZ, thereby further consolidating its market presence.

SustainabilityAn integral part of our corporate strategy
For us, sustainability means acting responsibly towards nature, society and all future generations.
When extracting our raw materials, we ensure that mining is carried out in a resource-efficient manner. We backfill the resulting voids with approved mineral waste in line with the principles of the circular economy. In this way, we ensure the long-term stability of our mine workings.
Our location on the Moselle enables us to transport our materials across Europe in an environmentally friendly manner.
As a company in the raw materials industry, we regard energy efficiency as our duty and continuously invest in the modernisation of our plant.
We are committed to bee conservation by establishing and caring for bee colonies on our site.
