What De Krom does
De Krom B.V. is a privately held Dutch infrastructure main contractor (hoofdaannemer) providing integrated civil-engineering services in the Grond-, Weg en Waterbouw (GWW) sector. The company's service portfolio covers manual and mechanized paving, earthwork, specialized sewage installation and service, demolition, traffic management, and CO2-neutral maintenance, delivered as complete projects from demolition through handover under the 'ontzorgen' value proposition. Founded in 1997 by Leo de Krom and now led by brothers Johan and Martijn de Krom since the founder's death in 2014, the group operates from its headquarters in Etten-Leur with regional offices in Eindhoven and Lieshout and a specialist sewage subsidiary in Giessen (Zijlstra Infra), employing approximately 125 people. Customer mix is split between Dutch municipalities (Etten-Leur, Eindhoven, Rotterdam, Breda, Bergen op Zoom, Roosendaal, Rucphen, Halderberge, Moerdijk, Woensdrecht, Alphen-Chaam, 's-Hertogenbosch, ABG-gemeenten) and commercial enterprises (Lidl Nederland, ERA Contour, WonenBreburg, C-Cinemas, Transport van Overveld, Krinkels).
Core technology is concentrated in three co-owned vehicles: Streetrobotics B.V., which developed the Strobo autonomous paving robot in a five-year collaboration with De JongCeba (laser/radar, robotic arms, high-performance processors); ROMFIX, a sustainable two-component joint compound supplier used on projects such as Station Tilburg; and Infrabox, a paperless administration and compliance platform for contractors. De Krom operates 11 fully CO2-neutral maintenance crews and holds Level 5 of the SKAO CO2 Performance Ladder, the highest tier, alongside ISO 9001:2015, VCA**, PSO Trede 3, SEB, and BRL 9334 certifications. A pending industrial design registration covers a sound-dampening, water-permeable paver tailored for robotic installation.
The business model is project-based and exclusively B2B: revenue is generated through custom quotations and framework contracts, with acquisition driven by direct sales to municipal procurement and B2B commercial clients rather than consumer channels. Recent strategic actions include the 2024 establishment of De Krom Lieshout following the bankruptcy of F. Vereijken B.V. (absorbing 14 employees and equipment) and the 2026 acquisition of Steevens Wegenbouw in Valkenswaard, both extending the group's Brabant footprint. The company is family-owned with no disclosed external private equity or venture capital participation.
