H+H Deutschland

What H+H Deutschland does

H+H Deutschland GmbH is the German operating subsidiary of the publicly listed Danish parent H+H International A/S, headquartered in Wittenborn, Schleswig-Holstein. The company manufactures two complementary masonry product lines — Porenbeton (autoclaved aerated concrete) and Kalksandstein (calcium silicate / lime sand brick) — for the German construction market. Following the March 2018 acquisition of Heidelberger Kalksandstein GmbH (later renamed H+H Kalksandstein GmbH) and the 2019 majority stake in Baustoffwerke Dresden, H+H Deutschland operates a network of German production facilities including Wittenborn, Hamm-Uentrop, and Bad Bramstedt, placing the consolidated group as the second-largest Kalksandstein provider in Europe with approximately 15 factories across Germany, Poland and Switzerland.

The core technical offering covers large-format masonry elements (H+H Multielement), the licensed KS-QUADRO modular building system with the KS-QUADRO E variant, and the H+H Thermostein MW composite brick with integrated mineral wool insulation (U-value 0.16 W/(m²·K)). Value-added services include Multielement Plus factory pre-cutting with just-in-time delivery, minikran rental combined with element delivery, BIM objects, and the KS-Schallschutzrechner sound-insulation calculator. Products address structural, thermal, fire (non-combustible A1), and sound-insulation requirements for multi-family residential, healthcare, and social housing projects.

The business model is industrial B2B: products are priced per cubic meter (€/m³) via published regional price lists with key-account distribution through Baustoff-Fachhandel dealer cooperatives, supported by a regional sales manager (Gebietsberater) network. Customer segments include property developers, architects and structural engineers (specifiers), construction companies, and building material dealers. Recent commercial actions include energy and logistics surcharges effective April 2026 and a social media relaunch in January 2024, alongside DGNB Navigator sustainability listing in March 2024.

Revenue model

1. Porenbeton and Kalksandstein Masonry Products: H+H Deutschland generates revenue primarily through the sale of masonry building materials including aerated concrete (Porenbeton) and lime sand brick (Kalksandstein) products. Products are sold through building material traders (Baustoff-Fachhandel) and directly to construction companies. The company operates factories in Germany and sells throughout the German market.
2. H+H Multielement Plus Pre-cutting Service: Value-added service where aerated concrete elements are factory-precut to exact dimensions based on architect's plans and delivered just-in-time according to construction progress. Additional service fee for precision cutting and commissioning.
3. Minikran Rental: Mini crane rental service combined with delivery of H+H Multielements, allowing construction companies to efficiently process large-format masonry elements without capital investment.

• Leipfinger-Bader: Leipfinger-Bader is a leading German brick and masonry manufacturer offering facing bricks, clay blocks and energy-efficient wall systems. It competes with H+H for wall construction specifications in German residential and commercial projects.
• Cirkel GmbH & Co. KG: Cirkel is a German manufacturer of calcium silicate (Kalksandstein) bricks, directly competing with H+H Kalksandstein in identical products, German dealer channels, and Bundesverband-led specification frameworks.
• Röben Tonbaustoffe: Röben is a major German manufacturer of facing bricks, clay blocks and related masonry products. It competes with H+H in the German residential wall-build specification market, particularly for visible masonry and multi-family construction.
• Schlagmann Poroton: Schlagmann is a major German producer of vertically perforated clay bricks (Poroton) used in monolithic exterior walls. Its energy-efficient clay block systems compete head-to-head with H+H Porenbeton in the same specification channel.
