What Sireg Geotech does

Sireg Geotech S.r.l. is a privately held Italian family-owned manufacturer, founded in 1936 and headquartered in Arcore (Monza-Brianza), that produces non-metallic and composite products for geotechnical and civil engineering applications. The company operates three production sites in Lombardy (Arcore, Agrate, Ronco Briantino) totaling approximately 25,000 m², with a 51-100 employee base and a near-90-year history under the Blanc family (currently led by third-generation CEO Sonja Blanc, with fourth generation joining in 2026).

Its product portfolio is organized in two technology families: (1) thermoplastic and thermosetting PVC/PE products — DURVINIL® valve/injection and drainage pipes, sonic pipes, DURVITECH® inclinometer casings, FLEXVINIL® waterstop joints, and DUROTENE® corrugated sheaths; and (2) fibre-reinforced polymer (FRP) composites — DURGLASS® and GLASSPREE® TS glass-fiber rebars (GFRP), CARBOPREE® carbon-fiber bars and laminates, and ARAPREE® aramid-fiber products, with self-drilling anchors, rock bolts, and fiberglass mesh for soil nailing and tunnel reinforcement. GLASSPREE® TS is the first GFRP rebar in Europe to receive CE marking (January 2025) and the only one with an ETA (ETA 22/0168, October 2022) and EPD certification, supporting up to 100-year durability claims in saline, electromagnetic, and chloride-rich environments.

Sireg sells primarily through direct enterprise field sales with bundled technical consulting — calculation reports, specifications, design drawings, and on-site installation assistance — supplemented by a six-country authorized distributor network (Greece, Poland, Belgium, Turkey, Israel, Germany). Pricing is quote-based and undisclosed. 60% of turnover is generated outside Italy across 70+ countries, with reference projects including Grand Paris Express, Crossrail/Elizabeth Line, CERN LHC, the Tower of Pisa, the Louvre, and the Basilica di San Francesco d'Assisi. The company invests 5% of turnover in R&D, holds ISO 9001 certification since 1997, and is developing a next-generation recyclable thermoplastic-matrix FRP rebar in partnership with Arkema. Related subsidiaries Sireg Hydros (water treatment, 1988) and Sireg Polyvinyl (PVC battery separators) sit outside the core geotechnical business.

• Mapei S.p.A. Italian-headquartered global manufacturer of adhesives, sealants, and chemical products for construction including structural reinforcement systems. Regional Italian peer with overlapping customer base (civil engineers, contractors) in the Italian and broader European construction chemicals market, and a comparable specialty industrial profile.

Broad incumbents

• Owens Corning: US-headquartered global building materials company producing glass fiber reinforcements, composites, and insulation solutions for construction and infrastructure. Broad incumbent with fiberglass material science capabilities that could enter or expand in the FRP rebar market, representing an indirect but credible competitive threat to Sireg's GFRP rebar business.
• Saint-Gobain: French-headquartered global leader in building materials with operations spanning construction chemicals, composites, and infrastructure products. Broad incumbent whose scale, R&D resources, and distribution network could enable it to enter or rapidly expand in the FRP reinforcement segment, posing a long-term competitive risk to niche players like Sireg.
