What Klaus does
KLAUS Gruppe is a family-owned German construction group headquartered in Augsburg, Bavaria, operating through five wholly-owned subsidiaries: KLAUS Wohnbau (residential development), KLAUS Hoch + Tiefbau (building construction, civil engineering, concrete prefabrication, raw material extraction), ECKLE Tiefbau and HOLL Tiefbau (regional civil engineering and road construction), and recycling+ GmbH (construction material recycling). The group serves private residential customers, commercial/industrial clients, and public-sector/municipal authorities primarily across the Augsburg, Munich, Ulm, and surrounding Bavarian corridor regions. The legal entity is structured as KLAUS GmbH & Co. KG, a German limited partnership, with KLAUS Geschäftsführungs-GmbH as general partner and Dipl.-Ing. (FH) Jörg Klaus as Managing Director (Geschäftsführer).
The company's core technology stack centers on physical construction execution rather than software, anchored by vertically integrated capabilities spanning raw material extraction (own gravel pits in Königsbrunn and Lösau), in-house concrete prefabrication (~12,000 customized components annually at the Kissing facility, including stairs, balconies, facades, and structural elements), and full-service construction delivery. A distinctive proprietary offering is the DINO® Dachhebesystem (Roof Lifting System), a patented hydraulic technology developed since 1992 that lifts existing roof structures to enable attic conversion or floor expansion without demolition, with over 1,500 completed installations including heritage-protected buildings. KLAUS Hoch + Tiefbau additionally holds TÜV SÜD certification as a specialist firm under §19 I WHG (German Water Resources Act) for handling water-hazardous substances.
The revenue model is project-based professional services plus hardware sales (prefabricated concrete elements and raw construction materials), with no publicly disclosed pricing. GTM is sales-led and regionally anchored, with each subsidiary operating in defined geographic territories and customer segments (private, commercial, public), acquired via direct outreach, referrals, project tenders, and regional market presence. Distribution runs through dedicated subsidiary websites, Instagram channels for KLAUS Hoch + Tiefbau and KLAUS Wohnbau, and a recruitment-focused careers portal. Marketing emphasizes the multi-generation family-business identity, regional roots, and integrated "all construction services under one roof" value proposition.
