What GKB Group does

GKB Groep is a privately held Dutch civil-engineering and outdoor-infrastructure contractor headquartered in Barendrecht, Zuid-Holland, founded in 1946 and now transitioning from third- to fourth-generation Kraaijeveld family leadership effective January 1, 2026. The company designs, builds, and maintains public outdoor space — bridges, parks, sports complexes, playgrounds, waterway revetments, dredging works, road and water construction, and custom steel structures — for a client base dominated by municipalities (Rotterdam, Barendrecht, Den Haag, Roosendaal) and regional water boards (Hoogheemraadschap Delfland, Waterschap Hollandse Delta), with secondary work for education, zoo, and sports clients such as Feyenoord and Diergaarde Blijdorp. Operations run through six wholly-owned divisions — GKB Realisatie (project execution), GKB Staalwerk (steel fabrication), GKB Machines (custom machinery including electric dredging equipment), GKB Materieel (equipment rental), GKB Visie (planning and design), and Grondbank IJsselmonde (earthworks). GKB has built out proprietary zero-emission dredging and construction fleets, a custom machinery capability for complex sites, and an internal vocational academy (GKB Bedrijfsschool) offering MBO and HBO programs in partnership with Hoornbeeck College and SDO Hogeschool, supplemented by 60 social-return placements. The company employs 51-100 staff, operates within the Zuid-Holland province, and generates revenue through project-based contracts tendered by Dutch public-sector buyers.
