Viafin Service has grown significantly during its operating history.

The roots of the company are in the machinery operations of Viafin Oy. Industrial process piping has been manufactured in various Viafin group companies. In 2008 Viafin Oy made the strategic decision to invest more in the industrial process piping business and opened two regional units the following year in Jämsä and Pori. In 2011 the business was consolidated into one company called Viafin Process Piping Oy. The same year the company made its first acquisition and expanded to Keminmaa.

During 2012-2016 The company expanded its network of regional units to Kurikka, Tampere, Vantaa and Lappeenranta. The Vantaa operations were consolidated under a single company called Viafin Uusimaa Piping to provide incentive structures for the employees and to pilot new operating models.

Viafin installation Oy was formed in 2017 when Viafin West Welding sold its installations and maintenance services to Viafin Installation.

During the spring in 2018 Viafin Process Piping expanded to hydraulics and small bore piping. And during the summer the same year the new parent company of the group Viafin Service Oy was formed.

Viafin Service Oyj acquired Gasum Tekniikka Oy in February 2019. Gasum Tekniikka Oy became Viafin Gas Oy that same spring and provides today a wide range of services for LNG and biogas systems, production and distribution.

Viafin Industrial services Oy was established in 2019 to build a comprehensive offering regarding industrial services and maintenance needs for various industries.
