What H & B Grondstoffen does
H & B Grondstoffen is a Dutch trading company (C.V. structure) founded on 1 July 2011 and headquartered in Krimpen aan den IJssel, Netherlands. The company supplies mineral construction raw materials — including lava, limestone, basalt, gravel, and pumice — to the Dutch civil infrastructure, municipal public works, horticulture, sports construction, and rail markets. It is jointly owned by Holcim, a global building materials group, and Basalt Union, a German family-owned basalt producer with more than a century of quarrying history, providing direct upstream access to primary raw material sources.
The product portfolio spans lightweight fill, foundation materials, sports-technical bases, aggregates, paving materials, hydraulic engineering supplies, rail ballast, geotextiles, and roof garden substrates. Beyond raw minerals, the company has developed proprietary branded systems including Porodur®, Eifellith®, Porodrain Systeem (stormwater management), Balastan Systeem (paving), and IJslandse Bims (RHP-certified Icelandic pumice for horticulture). Distribution is operated through seven depot locations across the Netherlands, with port-side bulk handling at Stein and a new depot opened in Meppel on 1 January 2022; export shipments have also been referenced to Portugal.
The business model is project-based B2B trading. H & B sources from parents' quarries and third-party producers, holds inventory at its depots, and delivers bulk tonnages to large civil contractors (BAM Infra, Strukton, Dura Vermeer, Swietelsky), municipal governments (Den Haag, Westland, Zoetermeer, Amsterdam), and niche customers (Jiffy, DCM in horticulture). Pricing is per-tonnage on large infrastructure projects — single deliveries of up to 11,000 tons have been recorded — supplemented by technical advisory and substrate specification services. Revenue is volume-driven, dependent on Dutch public infrastructure spending cycles, with limited financial disclosure in the public domain.

H & B Grondstoffen product offering
Product offeringCore offering
H & B Grondstoffen trades and distributes mineral construction raw materials—including lava, pumice, basalt, limestone, and gravel—through a network of seven depot locations across the Netherlands. The company supplies these materials to civil engineering contractors, road and rail builders, hydraulic engineering projects, sports field constructors, municipalities, and horticulture operators.
Product overview
H & B Grondstoffen operates as a single, unified product line — a curated portfolio of primary and secondary mineral construction raw materials — rather than a software-style platform-plus-modules architecture. The portfolio is organised into named product groups that map directly to construction applications: lightweight fill materials (Flugsand, Vulkaan Bims, Porodur®/Eifellith® Lava, IJslandse Bims), foundation materials (Hoogovenslakmengsel/LD-Mix, Porodur® & Eifellith® Lava, recycling material), sports-technical bases (Porodur®/Eifellith® Lava, Vulkaan Bims), aggregates/additives (Grind, Kalksteen, Basalt, Industriezand, Grauwacke), hardening/paving systems (Splitsoorten, Ternairzand, the Balastan Systeem), water-construction materials (Basalt, Basaniet, Kalksteen), railway ballast, geotextiles, roof-garden substrates and the water-permeable underlayer. These physical products combine into engineered systems such as the Porodrain Systeem (Porodur Lava 4/32 + Moraene Split 2/6) for stormwater storage/buffering and the Porodur® Lava-based climate-adaptive road/parking/sport constructions. The portfolio is distributed through a national depot network (Krimpen a/d IJssel, Den Bosch, Tiel, Meppel, Stein, Rotterdam) backed by a new fully electric PLM 827E crane at the main Krimpen depot.
