Dekker Groep

What Dekker Groep does

Dekker Groep (legal entity Dekker groep BV) is a family-owned Dutch company headquartered in IJzendoorn along the Waal river, founded around 1920 and now run by the fourth and fifth generations of the Van den Broek family. Its core activity is the extraction and processing of sand, gravel, clay, and reconditioned soil from Dutch riverbeds, supplemented by concrete production (multiple betoncentrales) and an owned logistics fleet. Production sites span the Netherlands, Belgium, France (LGR Les Gravières Rhénanes), and Germany (DMA Mineralaufbereitung GmbH), supported by specialized vessels including the Rotterdam 10, Rotterdam 26, Rotterdam 55, Rotterdam 58 and the floating Emmy Yvonne installation.

The company differentiates itself through a nature-inclusive extraction model that pairs raw material recovery with landscape development along rivers, covering biodiversity, flood safety, recreation and climate adaptation. It operates under a B2B/direct-to-customer motion, servicing the Dutch construction industry alongside public-sector clients such as Rijkswaterstaat and municipalities via public-private partnerships; pricing is quote-based, undisclosed publicly, and contracts can run multi-year. Notable projects include the 12 km Midden-Waal development zone (Dodewaard to Tiel), the Gouverneurspolder and Willemspolder sites, and the KRW-geul channel construction where 1.6 million m³ of sand was moved five years ahead of schedule.

Dekker's technology stack is built around proprietary autonomous electric vessels and on-site renewable energy, including the industry-first Rotterdam 10 (fully electric, AI-driven "smart body" autonomous sand suction vessel) and the Rotterdam 26 (100% electric cutter suction dredger with 10kV shore connection), as well as a 72,000-panel floating solar park at Bomhofsplas in partnership with Groen Leven. Sustainability credentials are extensive: ISO 14001, ISO 45001, CSC Platinum (Concrete Sustainability Council), BENOR, KOMO, BRL 2502/9321/9313, PFAS declarations and EN 12620 compliance. The company achieved an 80% CO2 emission reduction per ton of produced product in 2021, eleven years ahead of its 2032 zero-emission target, with government, energy and academic partnerships (Rijkswaterstaat, Blauwvinger Energie, Wageningen University, IVN Natuureducatie) reinforcing its positioning as a regulated, sustainability-licensed extract-and-develop operator in North-West Europe.

Core offering

Dekker Groep extracts and processes sand, gravel, and clay from Dutch riverbeds and operates concrete plants, supplying construction-grade aggregates. The company also provides nature-inclusive landscape development services that combine raw material extraction with floodplain restoration, biodiversity enhancement, and recreational area creation. Operations span the Netherlands, Belgium, France, and Germany through own production locations, vessel fleets, and public-private partnerships.

Product overview

Dekker Groep is a family-owned company with over 100 years of experience in extracting and processing construction raw materials from Dutch river beds. The core product portfolio includes sand (zand), gravel (grind), and clay (klei), along with ground for rearrangement (grond voor herinrichting) and concrete production (beton). These raw materials are extracted at various Dutch locations using specialized vessels including Rotterdam 10, Rotterdam 26, Rotterdam 55, and Emmy Yvonne. The company integrates these extraction operations with landscape development services (gebiedsontwikkeling), combining sand and gravel extraction with nature-inclusive development of river forelands. Additional services include trade and logistics (transport fleet, transshipment, inventory management), and a technical service division. The company operates in the Netherlands, Belgium, France, and Germany with over 250 employees.
