2024
Since the beginning of the year, the special civil engineering company Stump-Franki has been operating on the market as an independent service area under the PORR brand. This strengthens PORR's integrated approach as a full-service provider offering all steps along the value chain of a construction project from a single source.
2019
In April 2019, Stump-Franki Spezialtiefbau GmbH was formed through the merger of Stump Spezialtiefbau and FRANKI Grundbau. Both companies bring many years of experience and expertise to the joint venture and complement each other perfectly.
2013/2017
In 2017, FRANKI Grundbau GmbH & Co. KG, based in Seevetal, will also be taken over by PORR. Extensive investments in the construction of new Atlas equipment and FRANKI pile drivers are decided upon.
The takeover of Stump Spezialtiefbau GmbH by the PORR Group in 2013 strengthens the international orientation.
1990 / 1995
With the expansion of diaphragm wall technology at FRANKI Grundbau (1990) and the integration of Brechtelterra Spezialtiefbau und Umwelttechnik GmbH into Stump Spezialtiefbau GmbH in 1995, the portfolio was expanded to include the construction of more complex construction pits with all trades from a single source.
