Lek-sloopwerken

What Lek-sloopwerken does

Lek-sloopwerken is a privately held Dutch civil engineering and demolition contractor headquartered in Woerden, Netherlands, founded in 2009 by Maarten Lek and Peter de Korte. The company operates four integrated service lines—Sloopwerken (demolition), Betonbewerking (concrete processing), Sanering (remediation), and the Lek Mining circular demolition division—serving government infrastructure agencies, housing corporations, project developers, contractors, and fellow demolition companies. Project execution spans the Netherlands and internationally, with documented engagements in Spain (Steel Factory Zaragoza, FC Barcelona's Camp Nou) and Sweden (Stockholm Stureplan, Garpenburg silver mine). The firm operates a multi-brand structure under wholly owned subsidiaries Lek Betonbewerking B.V., Asbest Assist B.V., Lek Mining, and regional entities Lek-Sloopwerken Westland and Asbest-Assist Westland.

The company's technical platform is built around heavy capital equipment, including hydraulic demolition excavators from 1 to 210 tons with reach up to 64m height and 32m depth, anchored by the Liebherr R980 demolition crane—one of the world's largest sustainable demolition cranes, featuring EU Stage 5 emissions compliance and 90% nitrogen reduction. Specialized techniques include diamond-blade concrete sawing (blades up to 2000mm diameter, cutting depth 92cm), high-frequency rail sawing, NXburst non-explosive sensitive blasting, hydraulic boom drilling to 4m depth, and bush hammering. The Lek Mining circular division introduces a sustainability-oriented service line that reportedly recycles 95% of demolition waste into certified construction materials through a partner offtaker network.

Lek-sloopwerken operates a project-based professional services model with each engagement custom-priced based on scope, equipment requirements, and complexity rather than published rate cards. Revenue is generated through multi-year infrastructure contracts, tenders, and direct engagement often beginning at the pre-trajectory phase. The firm maintains an extensive regulatory and certification portfolio—ISO 9001, ISO 14001, VCA**, Veiligheidsladder Trede 3, SVMS007, CO2 Prestatieladder niveau 3, SC-530 for asbestos removal, and BRL 0509 for structural anchors—that functions as a gatekeeper for public infrastructure tenders. Revenue is not publicly disclosed; the company is privately held with no identified external institutional investors, growth has been funded internally and through equipment financing partnerships such as Deutsche Leasing.
