De Hamer

What De Hamer does

De Hamer Beton B.V. is a Netherlands-based prefab concrete manufacturer founded in 1938 in Nijmegen by G.A. van Gent, specializing in concrete solutions for two end-markets: underground drainage infrastructure (riolering) and above-ground paving infrastructure (bestrating). The company operates three production sites — Nijmegen (headquarters and underground infrastructure), Heumen (tiles, kerbs, and stones), and Waspik (tiles and stones) — employing approximately 160 permanent staff and functioning as one of ten specialized brands within the BTE Groep conglomerate. Its product portfolio includes proprietary branded systems such as the Hapro concrete pipe system (with self-lubricating lamella slip connections and on-site cutability), Columbuis egg-shaped drainage pipes, MetroMax polymer concrete pipes for industrial wastewater, SilenTONE noise-reducing paving stones, Aqua MensuraStone climate-adaptation paving, the Permeo infiltration system, and the 4U-tegel reduced-material tile. All products incorporate ≥15% recycled concrete granulate as standard, with specialty SKUs reaching 50%, and the company supports HVO 100 sustainable-fuel logistics claiming up to 90% CO2 savings versus fossil diesel.

The company's go-to-market is exclusively sales-led and directed at the professional Dutch GWW (grond-, water- en wegenbouw) sector — municipalities, water boards (waterschappen), and civil engineering contractors — with no direct-to-consumer channel. Revenue is generated through one-time sales of prefab concrete products, supplemented by distance-banded HVO 100 and diesel surcharges that function as transparent pass-through pricing for logistics. Customer engagement is structured around chain collaboration (ketensamenwerking), a dedicated single point of contact, and a bestekservice specification portal that embeds De Hamer products into public tender documents. Distribution is entirely domestic across the Netherlands, with the company explicitly declining to process quotations from private individuals.

De Hamer maintains an extensive certification portfolio that effectively functions as a regulatory moat for public tender participation: ISO 9001 and ISO 14001 across all sites, multiple KOMO product certificates for pipes, tiles, kerbs and inspection chambers, CSC certification for responsible sourcing, CO2-Prestatieladder (with a 2026-06 recertification), BRL K11002 for environmental profiles, and PSO Trede 1 for social enterprise performance. The company participates in the EU LIFE-funded Invie (CIRRCON) circular concrete project via BTE Groep, signalling a strategic orientation toward low-carbon and circular product development. Ownership is wholly held by BTE Groep with no independent institutional shareholders.

Revenue model

1. Prefab concrete product sales: De Hamer generates revenue primarily through the manufacture and sale of prefabricated concrete products for drainage (rioleringssystemen) and paving (bestrating). Products include drainage pipes, inspection shafts, outlet structures, infiltration systems, paving stones, tiles, and kerbs. The company also generates ancillary revenue through HVO 100 surcharge (sustainable fuel surcharge per delivery) and diesel/energy surcharges for logistics, applied based on distance and tonne-kilometres.

Core offering

De Hamer manufactures and supplies prefabricated concrete products for two main infrastructure categories: underground drainage (rioleringssystemen) including concrete sewer pipes (Hapro), egg-shaped pipes (Columbuis), permeable infiltration pipes, polymer concrete pipes (MetroMax), inspection chambers (HamQuick), outlet structures, and underground waste containers (Velin); and above-ground paving (bestrating) including kerbs, paving stones, paving tiles, grass-reinforcing tiles, revetments, and specialized products such as SilenTONE noise-reducing stones, Wascon washed tiles, and VoegStone/VoegTegel weed-prevention paving. Products are sold exclusively to professional GWW buyers (municipalities, contractors, engineers) in the Netherlands, delivered directly from three production sites in Nijmegen, Heumen, and Waspik.
