What Van de Haar Groep does

Van de Haar Groep is a privately held Dutch regional contractor headquartered in Wekerom, Gelderland, with a secondary operational office in Arnhem. The company provides integrated outdoor space construction and maintenance across three divisions — Infra (civil engineering, road construction, sewer systems, residential area preparation), Groen (green space design, ecological construction, invasive species management, and nature compensation), and Sport (sports field maintenance and data-driven monitoring). It serves municipal governments, water boards, educational and healthcare institutions, and select private developers across the Midden-Nederland region (Gelderland and Utrecht provinces), acquiring work primarily through public sector tendering supplemented by direct engagement with community organizations.

The company employs proprietary or specialized methods including the WAVE thermal weed control system with sensor-based pavement scanning, GPS-guided line marking robots, sensor-based field moisture monitoring, sewer relining via the Kousmethode, and CleaRoot biological invasive plant control. Revenue is generated through one-time project contracts (with disclosed individual values ranging from approximately €135K to over €6M) and recurring multi-year maintenance framework agreements with municipalities. The company holds CO2-prestatieladder niveau 5 (the highest level), BRL7001 soil remediation certification, and RANOX natuuraannemer status, which together serve as gating qualifications for many Dutch public tenders.

Van de Haar Groep operates a sales-led, relationship-driven go-to-market anchored by named project managers who serve as relationship owners for specific municipalities and service areas. Its headcount is reported at 50-80 specialists (with one source indicating 80+), and it actively recruits across divisions. The business model combines civil engineering and ecological expertise into a single point of responsibility, reducing coordination complexity for public sector clients, and includes Social Return obligations delivered through partnerships with regional labor development organizations.
