S&B Strategy advises Hannover Finanz on the acquisition of Rohrsanierung Jensen GmbH & Co. KG

Our team advised HF Equity, a division of Hannover Finanz, on acquiring a majority stake in Rohrsanierung Jensen GmbH & Co. KG. The transaction was signed in November 2025.

Hannover Finanz has been the equity partner for medium-sized family businesses in Germany, Austria and Switzerland since 1979 and is itself a second-generation family-run company. The investment portfolio currently comprises around 30 companies with a total of over 13,000 employees and sales revenues of more than €4 billion.

Rohrsanierung Jensen has specialised in the trenchless rehabilitation and maintenance of sewage infrastructure since 2010 and currently employs around 110 people. The company stands for high-quality execution, technical expertise and strong customer satisfaction. Jensen has become the market leader in trenchless sewer rehabilitation in northern Germany and has already expanded successfully through the integration of a Hamburg-based sewer and culvert construction company.

The market for sewer rehabilitation is growing by around 5.6% annually and has a volume of approximately €1.3 billion. A key driver is high demand: over a third of Germany's 600,000-kilometre sewer network is in need of rehabilitation. Demand for efficient infrastructure service providers is rising accordingly.

S&B Strategy supported Hannover Finanz throughout the entire process leading up to the successful signing with commercial due diligence services.
