Zeker Zand

What Zeker Zand does

Zeker Zand B.V. is a Dutch sand and aggregate wholesaler headquartered in Sliedrecht, South Holland, and operating since 2022 as a wholly-owned subsidiary of dredging group Baggerbedrijf De Boer. The company supplies a comprehensive portfolio of construction raw materials — including ophoogzand, straatzand, drainage sand, sports-field sand, masonry sand, gravel in three grades, Argex pellets and sand, and menggranulaat (mixed crushed brick/concrete) — alongside soil products. Customers are primarily construction companies, project developers, civil engineering firms, and municipal or intergovernmental bodies executing infrastructure and residential projects in the provinces of South Holland, North Holland, Zeeland, and North Brabant.

The underlying operating model is vertically integrated: Zeker Zand self-extracts or procures material and handles loading, transport, unloading, and franco delivery to the customer's site. Its core technical asset is a privately owned fleet of hopper suction dredgers, beunschepen, and transshipment equipment, which allows waterway delivery to project quays (including shallow-water sites down to 2.60m draft) supplemented by road transport via AS-transport partners. Quality control is documented through in-house sieve analysts sampling vessels every five trips, and product certification under NL BSB (BRL9313, certificate ZW-017/4). The mbs Nevada sand suction vessel is equipped with a Stage-V engine and holds Gold-level Green Award certification, aligned with a group-level CO2 reduction target of 40–50% by 2030 versus 2015.

The business model is one-time, project-based B2B sales of bulk materials and logistics with delivery included; pricing is not publicly disclosed and is negotiated via contact form, with fuel surcharges indexed to a weekly KBN gasoil schedule. Go-to-market combines enterprise field sales for construction and infrastructure accounts with direct ordering for individual buyers, supported by a website, LinkedIn presence, and direct account management. The company does not sell via digital commerce platforms, has no mobile app or public API, and shows no AI/ML capabilities in its operating stack.

Functional benefit

Products and services

• Ophoogzand Sand used for raising gardens, driveways, ponds, or construction sites and for road construction as a stable foundation layer.
• Straatzand Natural sand used under paving work; clay-free and free of coarse organic matter, providing a stable, easy-to-level surface for street and tile work.
• Drainagezand Coarse-grained sand ideal as a base for sewage work due to its excellent water permeability.
• Sportveldenzand Sand for natural and artificial grass sports fields, available in multiple types for foundation or top layer with Kiwa ISA Sport/NOC*NSF compliance.
• Verschralingszand Sand used to improve (de-acidify) clay soils and for laying natural or artificial sports fields and horse arenas.
• Straatbrekerzand Very coarse sand (NEN 5104) used as sub-base for streets, tile work and industrial plates, bedding sand for paving, and gritting sand for asphalt.
• Speelbakkenzand Fine-grained, clean, pure sand for sandboxes and playgrounds.
• Vloerenzand Sand with grain size 0–4 mm, also known as concrete sand, used for concrete screed floors in residential and commercial buildings and for foundations.
• Metselzand Coarse sand for mortar and for use under paving with natural stone, with good water permeability.
• Bemeste tuinaarde Fertilized soil for filling or raising gardens and borders; quality improves through added fertilizers and lime.
• Andere soorten grond Various soil types including forest soil, fill soil, and mix soil.
• Grind 4/32 Gravel with grains between 4 and 32 mm, used in concrete, as roof covering, in drainage systems, or on garden paths.
• Grind 8/16 Gravel with grains between 8 and 16 mm, used in concrete, as roof covering, in drainage systems, or on garden paths.
• Grind 16/32 Gravel with grains between 16 and 32 mm, used in concrete, as roof covering, in drainage systems, or on garden paths.
• Ronde korrels (Argex) Round Argex pellets — expanded baked clay pellets that are draining, rot-resistant, durable, and non-combustible, used as light filling material and in green roofs.
• Gebroken korrels (Argex) Broken Argex pellets used for cable and pipe routes, as foundation material under brick and asphalt paving, as supplement for sewage, and for sports-field foundations.
• Argexzand Argex sand with properties similar to regular sand, used for cable and pipe routes, raising under walkways, supplementing sewage trenches, sports-field foundations, and liquid-tight paving.
• Menggranulaat 0/31,5 Menggranulaat (Repac) — a mixture of broken bricks and concrete rubble in which cement creates a hydraulic binding factor with hardening effect, used as surfacing for temporary roads or as foundation for permanent roads.
• Watertransport (Vóór de wal) Delivery by water before the dyke using Zeker Zand's own ships through Dutch inland waterways, with capability in shallow water down to 2.60 m depth; customers arrange their own transshipment from the dyke.
• Watertransport (Op de wal) Delivery by water to the correct location with transshipment handling; Zeker Zand arranges crane, conveyor belt, and funnel for complete unloading at the customer's site.
• As-transport Road delivery to the correct destination by truck, arranged for customers requiring delivery where waterway access is unavailable.

Broad incumbents

• Van Oord: Major Dutch dredging and marine contractor with own trailing suction hopper dredgers. Competes indirectly through dredging, land reclamation, and coastal protection projects where sand supply is bundled into the marine works scope.
• Heijmans: Major Dutch construction and infrastructure company that is a downstream buyer of sand and aggregates but also operates material supply arms. Relevant as a customer segment and as a broad incumbent shaping Dutch infrastructure demand.
• Ballast Nedam: Large Dutch construction and infrastructure group with active infrastructure, housing, and water projects in the same provinces where Zeker Zand operates. Comparable downstream demand profile and Dutch regional footprint.
• Koninklijke Boskalis Westminster: Large Dutch marine contractor and dredging group with extensive hopper fleet and reclamation capabilities. Operates broadly in the same Dutch waterways and dredging value chain where Zeker Zand sources and delivers sand, though at much greater scale and global scope.
• Sagrex (Heidelberg Materials): Benelux sand and gravel subsidiary of global building materials major Heidelberg Materials. Operates large-scale extraction sites across Belgium and the Netherlands with national distribution; broader and more capitalized than Zeker Zand but competing for the same Dutch construction buyers.

Direct peers

• Baggerbedrijf De Boer: Parent company of Zeker Zand and Dutch dredging contractor (Dutch Dredging). Operates in the same waterways, fleet category, and sand handling domain, sharing QSHE systems and resources — closest operational and corporate peer.
• Royal Smals: Dutch supplier of sand, gravel, and other bulk construction materials with own fleet and inland waterway delivery. Comparable size, product mix, and customer base in the Netherlands.
• Van Nieuwpoort Groep: Dutch family-owned sand, gravel, and recycled aggregate producer with extraction, processing, and direct delivery capabilities across the Netherlands. Directly comparable in product portfolio, Dutch market focus, and integrated supply-and-logistics model.

Regional players

• Bruil Infra: Dutch infrastructure and concrete/mortar supplier with own raw materials, batching, and logistics operations. Overlaps with Zeker Zand in metselzand, vloerenzand, and infrastructure supply to Dutch construction markets.

Others

• Grondbank / Repac menggranulaat producers: Specialized Dutch recycled aggregate (menggranulaat) producers and soil banks that supply competing circular construction materials. Indirect competitor on the recycled-aggregate share of Zeker Zand's portfolio.
