What Styrud does
Styrud Ingenjörsfirma AB is a Swedish specialty infrastructure contractor founded in 1963 that provides trenchless ("schaktfri") pipeline construction and drilling services to municipalities, construction contractors, and network companies across Sweden. Its core offering is the installation and renewal of underground pipelines for water, sewage, stormwater, district heating, fiber/telecom, and electrical cables without open-cut excavation, addressing the disruption, environmental, and reinstatement costs associated with traditional trenching. The company operates a multi-method "toolbox" spanning auger drilling, hammer drilling, directional drilling, microtunneling, and pipe jacking, supplemented by proprietary technology including the patent-pending StyroRock Navigator for rock environments, the helicopter-deployable electric Mutterknackaren drill rig, and drilling fluid recycling units that reduce waste and transport needs.
Styrud delivers services through a project-based contracting model priced per engagement, with nationwide coverage maintained through nine regional offices spanning Sävedalen (HQ), Stockholm, Göteborg, Malmö, Sundsvall, Arvidsjaur, Umeå, and Katrineholm, plus a workshop in Herrljunga. Sales and project execution are handled directly with municipal and enterprise buyers, supported by a framework agreement with Sinfra (since 2021) that allows member municipalities and utilities to procure without separate tendering. Named customers include Vellinge Kommun, Ronneby Miljö & Teknik, Jönköpings Kommun, Göteborgs Stad, Täby Kommun, Sollefteå Kommun, VA SYD, Laholmsbuktens VA, HEMAB, Kraftringen, Sveab, Mark & Energibyggarna, and JDI Entreprenad. Certifications include ISO 9001:2015 quality management and SP SITAC authorization for well-drilling competence.
Styrud operates as a wholly-owned subsidiary of Per Aarsleff Holding A/S (Aarsleff Group), a Danish construction and civil engineering group listed on Nasdaq Copenhagen. The June 2026 consolidation brought all Scandinavian trenchless drilling competence under Aarsleff's roof. Revenue, headcount, and financial performance are not publicly disclosed. The company markets documented outcomes of 70-95% CO2 reduction versus open-cut methods and project-completion speeds up to 2x faster than conventional excavation, and holds records including 124m hammer drilling in 813mm dimension in Sweden and 1,151m directional drilling between Møn and Falster in Scandinavia.
