Finexplo was established in July 2009 by Kalliotekniikka Consulting Engineers, who invited von Hertzen Consulting to join the group. Good relationships with a number of larger contractors ensured participation in a number of large underground projects including the Helsinki Metro extension and large underground parking facilities in both Helsinki and Tampere.
Finexplo had over the years a number of temporary warehouse facilities, but at the same time looked for a long term solution and to establish their own warehouse. This effort was successful and Finexplo established the existing facilities in Malmgård, Loviisa on long term basis. Later a second facility was added in Lappeenranta.
In 2016 von Hertzen Consulting bought out the Kalliotekniikka shareholding, leading to a 100 % ownership and has thereafter during 2017 invited new shareholders into the company. 2017 and 2018 has been a year of focusing on establishing closer relationships with existing suppliers, as well as bringing in new products, services and focus on inventory management.
