What Steg Entreprenør does

Steg Entreprenør AS is a Norwegian contractor specializing in NoDig (trenchless) methods for water and sewage (VA) infrastructure, headquartered in Geithus, Buskerud, and founded in 2012 by Kristian Sandum and Nils Skretteberg. The company operates a complete NoDig method suite — pipe bursting (Ø63–1000mm), pipe jacking (Ø300–1200mm), directional drilling (Ø32–1200mm, up to 1600m), tunneling (Ø1200–4000mm, up to 1500m), pilot tube drilling (Ø200–1200mm, ±20mm accuracy), and PE/PP welding up to 1200mm with seven NEMKO-certified plastic welders. It complements these with traditional construction operations (Anleggsdrift), offering hybrid projects that blend trenchless and open-cut approaches, and was the first company in the world to perform 100% electric pipe bursting while also piloting hydrogen-powered construction sites in partnership with NAPOP and Hafslund.

The company serves Norwegian municipalities, inter-municipal water companies, and main contractors as either direct supplier or specialist subcontractor. It operates in the public procurement market via competitive bidding and holds framework agreements with at least seven municipalities (Oslo, Drammen, Nesodden, Porsgrunn, Vestby, Frogn, Tinn), with disclosed contract wins ranging from NOK 17M to NOK 150M. Revenue is project-based and not publicly disclosed. The company is privately held and became a wholly-owned subsidiary of Aarsleff AS (Danish listed contractor, >NOK 25B revenue, ~8,600 employees) in 2021, gaining access to cross-border execution through Aarsleff Pipe Technologies, including a 2024 project in Malmö, Sweden. The company holds ISO 9001, Miljøfyrtårn, Sentral godkjenning, StartBank registration, and asbestos-pipeline sanitation approval, and has ~65 employees per recent company narrative.
