What Olimb Rørfornying does

Olimb Rørfornying AS is Norway's first and largest no-dig pipe rehabilitation company, founded in 1977 and headquartered in Råde, Norway. The company rehabilitates existing sewer and drainage pipes without excavation or demolition by installing a resin-saturated felt liner (strømpeforing / CIPP - cured-in-place pipe lining) inside the damaged host pipe and curing it with steam, hot water, UV-light or LED-light to form a new structural pipe. Complementary services include CCTV pipe inspection (rørinspeksjon), leak detection via smoke and color testing, route tracing using sondes, and high-pressure water jetting (spyling) up to 240 bar for pipes of 32-400mm diameter.

The company serves five primary segments: Public VA (municipal water and sewage networks, including manholes, culverts and stikkrenner), Borettslag og bygg (housing cooperatives and apartment buildings), private homeowners, industrial facilities, and roads/railways. Named reference customers include Klyve V Borettslag (NOK 70M+ saved vs. replacement), Fredly Borettslag (NOK 18M saved), Lyderhorn Borettslag (4,000 installations over three years), Drammen Kommune, Oslo Kommune Vann- og Avløpsetaten (multiple 2,000m+ contracts in tunnels and protected natural areas) and St. Olavs Hospital. Pricing is quote-based and project-specific, with free consultations and on-site assessments; no standardized pricing is published.

Olimb Rørfornying is a wholly-owned subsidiary of the Danish construction group Aarsleff, evidenced by the parent brand displayed prominently on the company's logo and website, and operates through four regional offices (Råde HQ, Grenland/Porsgrunn, Trondheim, Bergen) with direct field-sales teams and a 24/7 emergency service line in Bergen. The company holds SINTEF Technical Approval for internal pipe rehabilitation, first granted in 2010, which it leverages as both a regulatory and reputational moat. Its go-to-market is enterprise field sales supported by content marketing (magazine/blog), case-study libraries, social media (Facebook, LinkedIn, YouTube), and direct inbound phone/website contact for private homeowners and smaller jobs.
