What Dumoulin Bricks does

Dumoulin Bricks is a Belgian family-owned manufacturer of clay-based rapid-construction bricks, facing bricks, acoustic blocks, and complementary adhesive and robotic-construction systems, headquartered at a state-of-the-art automated plant in Roeselare with an additional depot in Genk. Founded in 1934 by Edward Dumoulin, the company has been rebuilt twice — most recently between 2008 and 2012, when the Vandermersch and Van den Braembussche families installed one of Europe's most modern quick-setting brick factories, using tunnel kilns, dryers with heat recovery, a 30,000 m² solar installation, and (from 2023-2024) an RTO for flue-gas cleaning. The product portfolio centers on BENOR-certified and EN 771-1-compliant blocks in 10–30 MPa variants (L-Block glue blocks, D-Block masonry bricks, XL adhesive blocks, AL25/AL30 acoustic blocks, K-Block EPB-compliant corner blocks) plus facing bricks in multiple formats and proprietary adhesive systems (COLL IT polyurethane and FOAM IT foam adhesive).

The company's go-to-market is sales-led and distribution-led: products are sold through a network of more than 60 building materials retailers across all three Belgian regions (Flanders, Wallonia, Brussels), supported by dedicated regional Account Managers for Antwerp, East Flanders, Flemish Brabant, Limburg, West Flanders, and Wallonia, who conduct on-site training and product demonstrations (notably for COLL IT and the WALL-Y cobot). The customer base is segmented across construction industry professionals (contractors and builders seeking rapid-build solutions), building materials retailers, architects and designers, and real estate developers. Pricing is not publicly disclosed; sales are quote-based and routed through dealers or direct pickup from the Roeselare facility (open 6 a.m.–6 p.m., with off-hours pickup by appointment), with a Genk depot enabling waterway-based distribution to eastern Belgium.

Dumoulin Bricks generates revenue primarily from hardware sales of bricks and construction materials, with the WALL-Y cobot (launched 2022) and its required XL adhesive blocks representing the company's flagship differentiator — a robotic construction system that can place two XL blocks at once and build 1 m² of rapid-build material in two movements. Strategic differentiation rests on regulatory certifications (BENOR, EPB, EN 771-1, PTV 23-003, CE), proprietary ancillary systems (WALL-Y cobot, Dualfix coupling anchors, building profiles, sawing tables), and complementary digital tools (2D texture generator, 3D facade design tool, and a TRISCO-based building-junction calculator). The company is privately held with no disclosed external funding, no public revenue figure, and no subsidiaries; ownership and operational leadership remain concentrated in the founding families.

Core offering

Dumoulin Bricks manufactures and sells fired clay construction bricks (L-Blocks, D-Blocks, XL Blocks, K-Blocks, AL-Blocks, BM65/BM90 module bricks) and facing bricks for facades. The company provides proprietary polyurethane adhesive systems (COLL IT. and FOAM IT.) for rapid-build construction, accessories such as clamps, sawing tables, and building profiles, and the WALL-Y collaborative robot (cobot) designed to place XL adhesive blocks. Products are sold through building materials retailers across Belgium and are used by contractors and builders for residential and commercial construction.

Product overview

Dumoulin Bricks is a Belgian family-owned brick manufacturer producing quick-setting bricks and construction solutions at a high-tech automated facility in Roeselare. The product portfolio centers on rapid-build construction blocks (L-blocks/glue blocks, D-blocks/masonry bricks, XL blocks, acoustic AL-blocks, and K-blocks/ceramic blocks) in various compressive strength ratings (10-30 MPa), complemented by facing bricks (Katty, Jules, Avenue Rouge, Oud Beveren, Edward, Old Zilverberg, Old Roobaert, Old Rumbeke) for facade applications. The company offers adhesive systems (COLL IT. and FOAM IT.) for structural bonding of blocks, accessories (building profiles, clamps, sawing tables, rolling tables, acoustic strips, coupling anchors, spray cans, glue guns, adhesive mortar), and the WALL-Y cobot robotic construction system for ergonomic placement of XL blocks. Digital tools include a 2D texture generator, 3D facade design tool, and construction cost estimator. Products are sold through building materials retailers across Belgium.

Products and services

• L-Block (Glue Blocks) Fired clay quick-build blocks with ground-flat surfaces (0.1 mm precision) for adhesive bonding in non-decorative masonry. Available in 10, 15, and 25 MPa compressive strength variants with large easy-to-grip handles and minimum 12 mm shell thickness. Used by contractors and builders for rapid-build construction.
• D-Block (Masonry Bricks) Fired clay masonry units for non-decorative masonry per EN 771-1 and PTV 23-003. Combines lightweight body, reduced porosity, and thick shell for good compressive strength, lower weight, and excellent workability. Available in 10, 15, and 25 MPa variants. For contractors and builders in residential and commercial construction.

Others

• Dualfix: Belgian technology partner that developed the coupling anchors for Dumoulin Bricks' adhesive-bonded prefabricated brickwork. Listed as an ecosystem participant rather than competitor; comparable as a Belgian construction technology specialist adjacent to Dumoulin's rapid-build system.
• CRH plc: Irish-headquartered global building materials conglomerate with significant European masonry and aggregates operations. While not a direct specialist in clay bricks, CRH's broad product portfolio includes clay brick and masonry products that overlap with Dumoulin's offering at a much larger scale.

Regional players

• Glen-Gery Corporation: US brick manufacturer producing facing bricks and specialty masonry products across multiple North American plants. Comparable product category but operates in a different geography (North America vs Belgium) and is owned by Brickworks Limited of Australia.

Broad incumbents

• Wienerberger AG: The world's largest producer of clay building bricks and roof tiles, headquartered in Austria with pan-European operations including Belgium. Wienerberger's Porotherm clay block system and Terca facing brick brand directly overlap with Dumoulin's quick-build L-blocks and facing brick portfolio, though at vastly greater scale and with broader geographic reach.
• Ibstock plc: UK market leader in clay brick manufacturing following the 2022 carve-out from CRH. Comparable product category (clay bricks and masonry) but operates at substantially larger scale and serves primarily the UK market rather than continental Europe.
• Forterra plc: UK-listed manufacturer of clay bricks, concrete blocks, and other building products with a major brick division (formerly Hanson Brick, Ibstock heritage). Comparable product category (clay bricks and masonry) but operating primarily in the UK market with much larger scale than Dumoulin.
• Michelmersh Brick Holdings: UK-listed brick manufacturer producing facing bricks, clay pavers, and special shaped bricks. Comparable in facing brick product category but with UK market focus and slightly larger scale than Dumoulin.
• Röben Tonbaustoffe GmbH: German family-owned brick manufacturer producing facing bricks, clay pavers, and clinker products across multiple European plants. Comparable in product mix and family-business model, but operates at larger scale and primarily serves the German market rather than Belgium.

Direct peers

• Nelissen Steenfabrieken: Belgian brick manufacturer specializing in facing bricks, brick slips, and clay pavers. Operates from a single site in Lanaken and competes with Dumoulin in the Belgian facing brick segment with a comparable product portfolio and similar regional focus.
• Vandersanden Group: Belgian family-owned facing brick manufacturer and one of Europe's largest, with multiple production sites in Belgium and the Netherlands. Vandersanden is the closest direct peer to Dumoulin in terms of geographic focus (Belgian market), product category (clay facing bricks and masonry units), and family-owned industrial heritage.
