What Tectum Group does

Tectum Group NV is a Belgian family-owned construction services group specialising in the full building envelope, focused on roofs and façades for commercial, industrial, institutional, government and heritage customers. Founded in 1993 and headquartered in Genk, the company operates more than 10 construction locations across Flanders, Brussels and Wallonia, alongside over 20 roofing-materials distribution branches under the CPE and Mawipex brands in Belgium and the Netherlands. Its core technology stack centres on flat and sloped roofing systems (EPDM, bitumen, slates, zinc, copper, lead, brass), green roofs, blue roofs with dynamic weather-forecast-driven retention, ventilated façade cladding, balustrades, fall protection and heritage restoration. The proprietary BossCover Circular System, a mechanically anchored EPDM roof with the patented Certefix click profile (co-developed with Claerhout Aluminium), is positioned as the world's first fully demountable flat roof and is paired with BossCover ROOFTILE XL, a recycled-EPDM roof tile.

Tectum makes money through project-based professional services (roofing and façade construction, plus heritage restoration), hardware sales of proprietary BossCover products and distributed third-party roofing materials, and recurring maintenance and emergency intervention work under the RoofComfort brand with a 24/7 service line. Pricing is quote-driven, valid for seven calendar days, with monthly invoicing in tranches (30% first tranche), 30-day payment terms, and no retention for works under €10,000. The go-to-market is enterprise field sales supported by project leaders, calculation specialists and account managers, with brand-building through content marketing, LinkedIn/Facebook/Instagram, employee ambassador campaigns, industry events and thought-leadership debates on circular construction. Customer segments are deliberately horizontal and include McDonald's franchisees (20+ projects), Amazon, Atlas Copco, Delhaize, Carrefour, Barco, Porsche, Volvo Trucks, Retail Estates, Pairi Daiza, the Royal Palace, the Flemish Parliament, NMBS, UZA Edegem and VUB.

Recent strategy has combined organic product innovation with disciplined M&A: acquisitions of SIX Dak & Gevel (2022, West Flanders) and Derbigum Services Belgium / DSB (May 2023) extended regional reach and added specialist bituminous-waterproofing and heritage capabilities. ESG positioning has been formalised through a €10M sustainability investment, a Belgian Green Building Council founding membership (April 2025), and a circular-materials take-back programme across distribution branches. Internal talent development runs through Tectum University in cooperation with VDAB, addressing the structural shortage of trained roofers.

Seven partnerships are on record, tiered core and minor.

• Belgian Green Building Council (BGBC)coreStrategic or Co-development Partner · 1 April 2025Tectum Group is a founding member of the Belgian Green Building Council, joining in April 2025. The company celebrated one year as founding member in March 2026. Membership supports the company's ESG strategy and positions Tectum in the sustainable construction ecosystem.
• Derbigum (Imperbel Group)coreStrategic or Co-development Partner · 1 May 2023Tectum Group acquired Derbigum Services Belgium (DSB) from the Imperbel group. The acquisition strengthened Tectum's relationship with Derbigum (a major Belgian bitumen roofing membrane producer in Perwez) and brought 60 additional specialists in Derbigum waterproofing installation. DSB was renamed DSB by Tectum.
• Retail EstatescoreStrategic or Co-development Partner · 1 January 2023Retail Estates provided its site in Kampenhout for the world's first fully circular flat roof pilot project. The company is investing €10 million in sustainability upgrades to its stores and partnered with Tectum to test and validate the BossCover Circular System in a real building environment. CIO Koenraad Van Nieuwenburg stated the company wanted to learn more about sustainable and circular applications.
• Claerhout AluminiumcoreTechnology or Integration · 1 January 2023Developed the Certefix click system in collaboration with Claerhout Aluminium. The patent for Certefix is shared/developed with this partner, and the aluminium mounting components are manufactured by Claerhout.

Direct peers

• Renolit: German plastics group producing single-ply roofing membranes (EPDM, TPO, PVC) under the RENOLIT brand, with significant European manufacturing. Comparable to Tectum on synthetic roofing membranes, especially given Tectum's BossCover EPDM circular system.
• IKO: Belgian/Canadian manufacturer of bituminous roofing membranes, waterproofing and insulation products with a plant in Belgium. Directly comparable to Tectum on bitumen roofing systems and shares a Belgian operating footprint.
• Carlisle Construction Materials: US-based manufacturer of EPDM, TPO and PVC single-ply roofing membranes (Carlisle SynTec) plus roofing accessories. Directly comparable to Tectum's BossCover circular EPDM offering; both centre on mechanically anchored EPDM systems though Carlisle is manufacturer-only and far larger globally.
• Soprema: French-headquartered global manufacturer of waterproofing membranes, thermal acoustic insulation and roofing systems. Highly comparable to Tectum on flat-roof waterproofing products (bitumen, synthetic membranes) and increasingly on sustainable/circular roofing, although Soprema is primarily a manufacturer while Tectum is a contractor-plus-product hybrid.
• BMI Group (Standard Industries): European roofing and waterproofing systems provider (formerly Braas Monier, Icopal) offering pitched and flat roof solutions across multiple European geographies. Comparable to Tectum as a roofing systems specialist with both products and installation heritage; BMI operates at significantly larger European scale.
• Bauder: German/UK family-owned manufacturer of flat-roof waterproofing systems including bitumen, single-ply membranes and green roofs. Closely comparable to Tectum on flat-roof product range, green/blue roof solutions and family-ownership structure with a contracting-adjacent product focus.
• Derbigum / Imperbel Group: Belgian bituminous waterproofing membrane manufacturer founded in 1932, based in Perwez. Directly comparable to Tectum on bitumen roofing products and was the parent of DSB (now DSB by Tectum) before the 2023 acquisition, making it both a peer and a former counterparty.

Regional players

• Willemen Groep: Belgian family-owned general construction group operating across building, civil engineering and real estate development. Comparable to Tectum as a Belgian family-owned construction platform of similar scale and culture, though Willemen is a broader general contractor rather than a roofing/facade specialist.

Broad incumbents

• Kingspan Group: Irish-listed global leader in insulated panels, building envelope and roofing/waterproofing solutions. Overlaps with Tectum on the building envelope (roofs and facades) and increasingly on sustainable construction, but operates as a much larger, publicly listed diversified building products group.
• Sika AG: Swiss-listed specialty chemicals company with a substantial roofing and waterproofing systems division (Sika Sarnafil single-ply membranes, bitumen systems). Comparable to Tectum on roofing/waterproofing products and on sustainability positioning, though Sika is a global, multi-segment chemicals incumbent.
