MHIGRUPPE

What MHIGRUPPE does

MHIGRUPPE, legally Mitteldeutsche Hartstein-Industrie Aktiengesellschaft, is a German family-owned producer of raw and construction materials headquartered in Hanau and operating 40 regional locations across central Germany with approximately 1,070 employees. Founded in 1906 and now in its fourth generation of Hagemeier-family ownership, the group extracts and processes natural stone (basalt, diabase, gabbro, granite, greywacke, limestone), produces asphalt and ready-mix concrete, and provides road and civil engineering plus bridge rehabilitation through its Strassing GmbH subsidiary. The product portfolio spans eight business lines: raw and construction materials (natural stone, asphalt variants including its aspha-min temperature-reduced asphalt, transport concrete); construction services (Strassing road/civil engineering and MHI Bohrtechnik/UniWork DrillTec drilling); recycling and fill operations; in-house logistics with a telematics-equipped fleet; in-house material testing laboratory services; and natural stone/specialty construction materials trading. MHI is recognized as a pioneer of 100% asphalt recycling in Germany and won the 2001 Prix de l'Innovation in Paris for its aspha-min low-temperature asphalt technology, which is positioned to benefit from a 2026 German regulatory shift making temperature-reduced asphalt the standard practice.

The company monetizes through hardware sales of construction materials, professional services for road construction and drilling, and recycling/disposal fees, with all pricing quote-based and B2B/government-tender oriented. Go-to-market is direct via 40 regional locations and 17 subsidiaries (MHI Asphalt, MHI Beton, MHI Naturstein, MHI Baustoff, MHI Bohrtechnik, Strassing, aspha-min, MHI Logistik, MHI Baustoffprüfung, Hartsteinwerke Thomas, Sauerländer Hartkalkstein-Industrie, Asphaltwerke Waldeck, and others), supported by regional sales teams covering Nord, Mitte, Süd, and Ost territories. Customer segments span public authorities (federal, state, municipal government, Deutsche Bahn), commercial construction companies, garden/landscape contractors, and private end customers. Distribution emphasizes regional proximity and short delivery distances as the primary value proposition. A 2026 corporate rebranding (new logo, typography, subsidiary wordmarks, and websites) and a 2026 investment in sustainable-asphalt startup ecopals indicate a forward-looking posture around digitalization, sustainability, and brand modernization.

Core offering

MHI Gruppe produces and supplies raw and construction materials including natural stone (basalt, diabase, gabbro, granite, greywacke, limestone), asphalt (including temperature-reduced variants under the aspha-min brand), and ready-mix concrete. Through its subsidiary Strassing GmbH it delivers road and civil engineering as well as bridge rehabilitation, complemented by recycling of bituminous road material, fill operations, in-house telematics-equipped logistics, and material testing laboratory services to public authorities, commercial construction companies, and private customers across central Germany.

Product overview

MHI Gruppe operates a diversified platform of construction material products and infrastructure services organized around four core pillars: (1) Roh- und Baustoffe — raw and construction materials including Naturstein (natural stone: Basalt, Diabas, Gabbro, Granit, Grauwacke, Kalkstein), Asphalt (multiple types: Asphaltbeton, Splittmastixasphalt, Gussasphalt, OPA, TA, Kaltasphalt), and Beton (transport concrete); (2) Bau — road/civil engineering and bridge rehabilitation via Strassing GmbH and drilling services via MHI Bohrtechnik GmbH (UniWork DrillTec); (3) Recycling und Verfüllung — responsible recycling of bituminous material and fill operations; and (4) Logistik — in-house transport and delivery. The group also maintains a Baustoffprüfung (material testing) laboratory division, a Handel (trading) business for specialty materials, and an aspha-min brand for temperature-reduced asphalt additives. The group comprises approximately 17 subsidiaries (including MHI Beton GmbH, MHI Asphalt GmbH, Strassing GmbH, aspha-min GmbH, Hartsteinwerke Thomas, Sauerländer Hartkalkstein-Industrie, and others) coordinating across 40 locations in central Germany. The enterprise traces its roots to 1906 and remains family-controlled in its fourth generation.

Scale indicators8 records

Recent moves11 records

Expansion highlights6 records

Broad incumbents

• CEMEX: Global cement, ready-mix concrete, and aggregates producer with German operations. Comparable across the cement-based construction materials value chain, though internationally diversified versus MHI's regional focus.
• STRABAG SE: Large European construction contractor with deep road and civil engineering operations in Germany. Directly comparable to MHI's Strassing GmbH subsidiary in road construction services, but operates at national/EU scale rather than regional.
• Eurovia (Vinci): Vinci subsidiary operating one of Europe's largest road construction and aggregates networks. Directly comparable to Strassing GmbH in road building and to MHI's asphalt production, though at EU-wide scale rather than regional.
• Holcim: Global construction materials giant with significant German aggregates, ready-mix, and asphalt operations. Comparable across the full construction materials value chain MHI addresses, though Holcim's portfolio is far broader and internationally diversified.
• Heidelberg Materials: Germany's largest cement, aggregates, and ready-mix concrete producer with national and international scale. Overlaps directly with MHI in aggregates, ready-mix concrete, and downstream construction materials, but operates at vastly larger scale across multiple geographies.
• CRH plc: Global building materials group with material German aggregates and concrete assets. Comparable in core products (aggregates, ready-mix) and integrated value chain, but operates globally with vastly greater scale and capital access.

Direct peers

• SCHWENK Baustoffe: German building materials producer with cement, ready-mix concrete, and aggregates operations primarily in southern Germany. Comparable in product mix (cement-based materials, aggregates) and Mittelstand character, but geographically non-overlapping with MHI's central German footprint.
• Basalt-Actien-Gesellschaft: German aggregates producer focused on basalt and other hardstone quarrying with regional sites. Directly comparable to MHI Naturstein as a quarry operator and aggregate supplier, though without MHI's downstream asphalt/concrete integration.
• GP Günter Papenburg AG: German Mittelstand construction and building materials group with aggregates, ready-mix concrete, asphalt, and civil engineering operations. Closely comparable integrated business model to MHI, though concentrated more in eastern Germany.

Regional players

• Asphalt-Bau GmbH & Co. KG: Mid-sized German road construction and asphalt paving contractor. Comparable to MHI's Strassing subsidiary in road construction services, though smaller and regionally focused without MHI's upstream aggregates integration.
