What Oldroyd does

Oldroyd AS, founded in 1994 and headquartered in Stathelle, Telemark, Norway, is a privately held family-owned manufacturer and supplier of membrane, drainage, and fastening systems for tunnels, buildings, and water/sewage infrastructure. The company develops and produces its products at a single factory on Skjerkøya in Telemark, and describes itself as the only Norwegian manufacturer of tunnel waterproofing membranes, claiming deployment in over 90% of tunnels across the Nordic countries. The product portfolio is organized around three verticals — Tunnel (MultiSafe series, Xtf fire-retardant membrane, RoadRunner reinforcement chair and surrounding accessory system), Building (DrainX, Xv, radon barriers, radon wells, Eco moisture barrier), and VA og Mark (pipes, chambers, stormwater channels) — supplemented by geomembranes, green-roof systems, and a broad fastening/sealant accessory range.

The underlying core technology is the proprietary OLDROYD Multi-Layer Technology: an LLDPE, PP, or TPO three-layer construction plus optional reinforcement, where the white inner surface improves tunnel work environment, the black middle layer provides visible damage detection, and a grey UV-stabilized outer layer resists environmental exposure. Fire-retardant variants (Xtf, MultiSafe RT) meet stringent Nordic tunnel fire requirements, with the MultiSafe RT featuring a patented edge-sealing solution developed specifically for Trafikverket. The injection-molded component line uses 100% recycled ocean plastic (Havplast) processed on KraussMaffei equipment, addressing both ESG procurement criteria and raw-material cost. Documented performance includes aging tests up to 120 years, matching the 100+ year design life of major tunnel infrastructure.

The business model is B2B/B2G hardware sales. Large infrastructure projects are won through direct sales by dedicated account managers (e.g., Sales Manager Tunnel) to contractors and government owners — Statens vegvesen, Bane NOR, Nye Veier, Trafikverket — with products specified into projects and supplied by named contractors such as Skanska, NCC, Implenia, Subterra, Strabag, AF Gruppen, and Kreate. Pricing is project-based and quote-driven, typically under multi-year framework contracts. A parallel wholesale channel operates through four Pick-up Points (Stathelle, Seljord 24/7 self-service, Skien, Bamble) serving mid-market ground-work professionals. Geographic reach is concentrated in Norway, Sweden, Denmark, and the Faroe Islands, with a recent UK entry via Newton Waterproofing distribution. The company is privately held with 11-50 employees, no external investors, no subsidiaries, and no public disclosure of financial results.
