The Central German Hartenstein-Industrie AG ( MHI ) is a German group of companies with a focus on raw materials production as well as in road and civil engineering . It has approx. 1000 employees and 47 production sites. The company's headquarters are in Hanau .
history
The company was founded in 1906 from businesses of the Rousselle family and Bayrische Hartstein-Industrie AG. The First World War, inflation in 1923 and the global economic crisis, in some cases severely affected, the company found itself in a situation that threatened its very existence at the end of the 1920s.
When Heinrich Hagemeier joined the company, the company recovered; Both sales and company results developed positively up to the beginning of the Second World War. The war years, on the other hand, were marked by a sharp drop in sales, a general shortage of skilled workers and the destruction of the administration building in Frankfurt.
The post-war years were also difficult for the Central German hard stone industry. The situation began to improve with the currency reform in 1948. The development was supported in particular by the introduction of full mechanization in selected plants and the increase in domestic demand.
The 1950s and 1960s were characterized by a further expansion of full mechanization in the factories and the associated increase in productivity, as well as an increased use of bituminous road surfaces.
In the mid-1970s, the plants were decentralized into four regional branches, which were converted into independent subsidiaries in the early 1980s. The existing business fields were expanded to include road construction and civil engineering, building materials trading and building material testing, as well as recycling and landfill .
After the reunification of Germany, MHI acquired several companies in the new federal states. In addition, the ready-mixed concrete business area was set up and developed in the 1990s . The R&D department of MHI developed the product aspha-min in the area of low-temperature asphalt . Later, the company set up its own logistics company in the Rhine-Main area .
Business segments
Natural stone
The core of the activity in the natural stone segment is the extraction, processing and classification of the raw material in 25 quarries (2013). The natural stone products made from basalt , diabase , gabbro , greywacke and limestone are used in industry as well as in agriculture and forestry.
Building materials
The business fields asphalt , concrete , trade and building material testing form the building materials segment in the MHI group.
The company operates 20 asphalt mixing plants. The MHI Group has been active in the ready-mixed concrete sector since 1991 and has since implemented construction projects in Hesse , Thuringia and Saxony-Anhalt .

Recycling and landfill
In the recycling business area, bituminous road debris is reused in the production of asphalt mix. The same applies to the processing and reuse of natural stone, concrete and building rubble from demolition measures. The landfill business unit disposes of customers' mineral waste.
construction
The construction segment includes road and civil engineering activities.
trade
The trade segment deals with the sale of natural building materials and special products for gardening and landscaping, road construction and civil engineering as well as in industry and agriculture.
Trade fair location
At the location in Nieder-Ofleiden , Hesse , Europe's largest basalt quarry, the Steinexpo , an international quarry demonstration fair for the raw materials and building materials industry, has been held every three years since 1990 . Since the exhibition areas change significantly due to the constant rock extraction, each exhibition must be completely redesigned from the start.
