What Polytechniek B.V. does

Polytechniek B.V. operates as the installation technology arm of Schadenberg Groep, a Dutch family-owned construction and infrastructure group with roots dating to 1947 and headquarters in Hem, Netherlands. The company designs, delivers, installs, and maintains technical installations spanning water technology, air treatment, cooling technology, heating, heat pump systems, electrical engineering, and measurement and control technology. Its customer base spans the construction, agricultural, industrial, and utility sectors, with named projects including hospital infrastructure expansions, agricultural conditioning cells, residential developments, hotel balcony renovations, and government infrastructure.

The core proprietary technology is the PT Solution process computer, an in-house developed controller for complex climate and process installations, with integration capabilities for third-party climate computers from Priva, VDH, and Sercom. Differentiated offerings also include the Waterneutraaldak circular rainwater system, which captures up to 80% of rainfall for rooftop garden irrigation, and the Vertuss vertical plant system installed and maintained for over 15 years. Polytechniek holds international market leadership in chicory hydroponic installations, operating across 21 countries, and has delivered energy-efficient cooling installations since 1980 with natural refrigerant expertise (ammonia, propane) and R22 replacement systems.

Commercially, the company generates revenue through project-based professional services contracts (design, installation, and maintenance) integrated with Schadenberg Groep's five other business units: Infrastructure, Construction, Roofing, Greenery, and Real Estate Development. Its go-to-market is direct B2B sales targeting governments, project developers, housing corporations, VVE owner associations, property managers, and industrial buyers. The business holds extensive certifications including ISO 9001, VCA**, BRL-6000 series, SCIOS, CO2 Performance Ladder, and Safety Culture Ladder Level 3, which are required for qualification on institutional and government contracts.
