Mibau Stema Group. Rock solid business.
We are a leading sustainable aggregates supplier to the building industry in Europe. Our core competences are reliable manufacture of high-quality aggregates and logistics solutions to the construction industry. 
In our quarries, including Jelsa, the largest in Europe, we extract around 17 million tons of high-quality crushed rock products every year. This material is used in the realization of infrastructure projects. Our own fleet of modern self-discharging vessels and over 40 port terminals along the coasts of the North and Baltic Sea ensure the rapid distribution of construction materials and efficient delivery to all construction sites. 
The success is based on more than 400 qualified employees in 7 countries. Together, we want to realize challenging rock solutions and change the construction industry to protect the environment. With optimized work processes and a more careful use of resources we make our industry more sustainable.
