Baustoffwerke Havelland

What Baustoffwerke Havelland does

Baustoffwerke Havelland GmbH & Co. KG is a privately held German building materials manufacturer founded in 1991 and headquartered in Oranienburg-Germendorf, Brandenburg, near Berlin. The company produces two core masonry product lines: UNIKA Kalksandstein (calcium silicate / lime sandstone) including the sustainability-differentiated UNIKA ecobluu® variant, and PORIT Porenbeton (aerated concrete). Its product portfolio spans standard formats (Kleinformate, Plansteine), large-format XL elements, pre-configured UNIKA Planelemente for waste-free construction, and complementary components (Kimmsteine, ISO-Kimmsteine for thermal bridge mitigation, U-Schalen, Stürze/lintels, Dünnbettmörtel). UNIKA ecobluu® employs a modified sand-lime-water formulation that reduces production-stage CO2 emissions by 40% and achieves near-CO2-neutral performance over a 50-year recarbonization horizon, supported by the Kalksandstein-Nachhaltigkeitsgütesiegel (KS-NGS) awarded in 2025.

The firm sells primarily to regional construction companies and builders across Oberhavel, Brandenburg, and the Berlin metropolitan area through an in-house sales organization comprising a commercial inside-sales team, a technical sales function, and four named field sales representatives, supplemented by regional building materials distributors such as Raab Karcher. Marketing channels center on technical publications, the KALKSANDSTEIN Bauseminar with KS Nord e.V., customer factory tours, distributor events, and community sponsorships. Approximately 80–90 employees operate from the single Oranienburg-Germendorf production site, with the workforce drawn from the surrounding region and many staff tenured since founding; the firm has held IHK Potsdam "Ausgezeichneter Ausbildungsbetrieb" recognition since 2009. The company is managed by Geschäftsführer Marco Engel (appointed September 2024) alongside Christian Bertmaring in a supporting role. The entity is a GmbH & Co. KG with no disclosed venture, private equity, or parent ownership, and has no subsidiaries.

Broad incumbents

• Wienerberger AG: Wienerberger is the world's largest producer of clay bricks and a broad masonry/building-solutions incumbent with German market presence. While it primarily competes in clay brick rather than Kalksandstein, its wall-system portfolio and German distribution network put it in indirect competition for the same builder relationships Baustoffwerke Havelland serves.
• Heidelberg Materials AG: Heidelberg Materials is one of the world's largest building materials groups with German heritage across cement, aggregates, concrete products and masonry. Its concrete-products division competes broadly with both Kalksandstein and aerated concrete offerings in Germany.
• Saint-Gobain Weber GmbH: Saint-Gobain Weber produces masonry mortars, renders and wall-system components in Germany, and the broader Saint-Gobain group includes aerated-concrete and insulation activities. It is an indirect competitor in the German masonry wall-solutions space where Baustoffwerke Havelland operates.

Direct peers

• H+H Deutschland GmbH: H+H Deutschland produces both Kalksandstein and Celcon aerated concrete masonry products for the German residential and commercial construction market. It is a comparable mid-to-large regional manufacturer serving a similar customer base and product mix to Baustoffwerke Havelland.
• August Lücking GmbH & Co. KG: August Lücking is a German Kalksandstein manufacturer producing KS plan stones, lintels and masonry components for the regional construction market. It directly overlaps Baustoffwerke Havelland's UNIKA Kalksandstein portfolio and mid-market builder customer segment.
• Xella Group: Xella is the largest aerated concrete manufacturer worldwide (Ytong, Hebel, Multipor) and also a Kalksandstein producer in Germany. It is the most direct competitor to Baustoffwerke Havelland's PORIT aerated concrete and UNIKA Kalksandstein product lines, competing for the same builders and developers in regional German markets.
• Emsländer Baustoffwerke GmbH & Co. KG: Emsländer is a long-established German Kalksandstein and walling-product manufacturer based in northwestern Germany. It operates in the same Kalksandstein category as Baustoffwerke Havelland's UNIKA line, with comparable plan-element products and regional building-supply distribution.
• Hans G. Hauri KG: Hauri is a German-Swiss family-owned Kalksandstein manufacturer offering KS plan elements and complementary masonry products. It serves a comparable mid-market construction customer base with the same core product (Kalksandstein blocks) as Baustoffwerke Havelland.
