Steinzeug-Keramo

What Steinzeug-Keramo does

Steinzeug-Keramo is a European manufacturer of vitrified clay pipe systems used in municipal wastewater and sewer infrastructure. Founded in 1957 in Hasselt, Belgium as Keramo NV, the company entered a joint venture with Wienerberger Group in 1991, was fully acquired in 2010, and now operates as a wholly-owned subsidiary under Wienerberger Infra GmbH, with management led by Johan Van Der Biest and Tom Deckers. It runs two production sites — Bad Schmiedeberg (Germany) and Hasselt (Belgium) — and distributes across 23 European countries via direct enterprise sales and regional dealer networks, supported by nine localized country websites and active corporate social channels.

The company's core product is vitrified clay pipe systems (branded "The One") manufactured from natural raw materials — clay, chamotte, and water — with a documented lifespan of more than 150 years. The portfolio is organized into four solution categories: Open Trench (new installation via traditional excavation), Trenchless (no-dig jacking pipes), Rehabilitation (manhole and sewer renovation), and Accessories (fittings and consumables such as joint lubricant), with a specialized product (KeraMat) offered in selected markets. Independent Life Cycle Assessments (LCAs) and Life Cycle Costing (LCC) studies underpin the sustainability and total-cost-of-ownership proposition.

Steinzeug-Keramo generates revenue through direct hardware sales of these pipe systems and accessories to two primary buyer groups: municipalities and public utilities responsible for wastewater networks, and construction companies/contractors executing sewer installation and rehabilitation projects. The go-to-market is sales-led B2B, with technical consulting provided by a dedicated service and support team; pricing is not publicly disclosed and is handled through direct sales engagement. Products carry CE Declarations of Performance across 16+ European jurisdictions and conform to PN EN 295, supporting tender eligibility for public infrastructure projects.
