Rohrsanierung Jensen

What Rohrsanierung Jensen does

Rohrsanierung Jensen GmbH & Co. KG is a German specialty contractor specializing in trenchless (grabenlose) rehabilitation of sewer and canal infrastructure. Founded in 2009 by Stefan Jensen and headquartered in Brügge, Schleswig-Holstein, the company serves municipalities, city drainage departments, and public utilities across Schleswig-Holstein, Hamburg, and Nordrhein-Westfalen through branch offices in Borchen, Warendorf, and Bochum. Its customer base includes Hamburger Stadtentwässerung, Kieler Stadtentwässerung, Stadtwerke Wuppertal, and Entsorgungsbetriebe Lübeck, with cumulative work exceeding 1,000 km of rehabilitated pipeline.

The company's core technology portfolio centers on UV-light-cured glass-reinforced plastic (GRP) hose liners (Alphaliner), seamless shaft liners (Vertiliner and Vertiliner XR), prefabricated pipe lining (Rohrlining) for diameters DN 800-4000, robotic repair systems for non-accessible wastewater canals (DN 800 circular, 600/900 egg profiles), flexible house connection liners capable of navigating 90° bends, and GFK structural rehabilitation with polyester and vinyl ester resins. All methods are designed for 50+ year service life and eliminate the need for open-cut excavation, reducing traffic disruption and surface restoration costs. Supporting capabilities include in-house civil engineering (Tiefbau), an equipment fleet including hydraulic excavators from 1.5 to 24 tons, wheel loaders, suction excavators, and high-frequency attachment rams.

The business operates on a project-based revenue model where contracts are awarded through German public procurement (VOB) bidding processes or direct negotiations with municipal clients. Pricing is determined per project through individual quotes rather than published rates. The company is privately held under a GmbH & Co. KG structure with two Managing Directors (Mehmet Sahan and Moritz Meis) and holds multiple sector certifications — Gütezeichen Kanalbau RAL-GZ S21.3, Gütezeichen Grundstücksentwässerung, AMS Bau, PQ VOB, and SK Qualität — that are mandatory for eligibility in German municipal infrastructure tenders.

Core offering

Rohrsanierung Jensen performs trenchless rehabilitation of sewer and pipe infrastructure for municipalities, city drainage departments, public utilities, and industrial clients. The company applies UV-curing GRP hose liners (Schlauchliner/Alphaliner), seamless shaft liners (Vertiliner), prefabricated pipe lining, robotic repair systems, and GRP structural rehabilitation, alongside complementary civil engineering services (Tiefbau). All projects are delivered as turnkey construction contracts awarded through public procurement or direct negotiations.

Product overview

Rohrsanierung Jensen offers a comprehensive suite of trenchless pipe and canal rehabilitation technologies. The core portfolio centers on the Alphaliner (UV-curing fiberglass hose liner) and Vertiliner (seamless shaft liner) systems, complemented by prefabricated pipe lining (Rohrlining), robotic repair systems, flexible house connection liners (Hausanschlusssanierung), and GFK structural renovation (Bauwerkssanierung). The company also provides full-service civil engineering (Tiefbau). Advanced variants include the Vertiliner XR for challenging installations and XL-Liner for large-scale projects. All solutions use glass fiber reinforced plastic (GFK) materials with epoxy or polyester/vinyl ester resins for chemical resistance and 50+ year durability.

Direct peers

• I.S.T. GmbH (Innovative Sewer Technologies): German-based trenchless pipe and sewer rehabilitation contractor offering CIPP, short-liner, and robotic repair methods. Comparable as a mid-sized German no-dig rehab contractor with a similar municipal customer focus and multi-method trenchless portfolio.
• Brandenburger Liner GmbH & Co. KG: German manufacturer and installer of UV-cured GRP CIPP liners (Brandenburger Liner). Directly comparable as a German trenchless rehabilitation specialist using UV-cured glass-fiber hose liner technology, similar in product offering (Alphaliner / BL liner) and customer base (municipal sewer rehab).
• Geiger Kanaltechnik GmbH & Co. KG: German specialized sewer and pipe rehabilitation contractor. Comparable in offering trenchless rehab services (liners, robotics, civil works) to municipal clients in Germany, with overlapping customer profile.
• Dommel GmbH: German trenchless pipe rehabilitation contractor offering CIPP, relining, and robotic repair services for municipal and industrial customers. Comparable as a German sub-scale specialist in trenchless sewer rehab competing for similar municipal tenders.

Broad incumbents

• Swietelsky-Faber GmbH Kanalsanierung: German trenchless sewer rehabilitation specialist (part of the Swietelsky group). Comparable as a national-scale no-dig sewer rehab contractor serving German municipalities with a similar portfolio of CIPP, robotic, and civil works services, though operating at larger scale and broader geography.
• Trelleborg Pipe Repair (part of Trelleborg Group): Industrial-group-owned provider of trenchless pipe rehabilitation systems including CIPP liners and seals. Comparable as a supplier/competitor in the no-dig rehabilitation materials space, though embedded within a much larger diversified industrial group.
• Per Aarsleff Holding A/S: Danish-listed specialty contractor with a major trenchless pipe rehabilitation division (Aarsleff Pipe Technologies) operating across Europe. Comparable as a leading no-dig sewer and pipe rehab contractor, though much larger and more geographically diversified than Rohrsanierung Jensen.

Emerging players

• Rädlinger primus line GmbH: German specialist in trenchless pipe renewal using flexible Primus Line liner systems for pressure pipes and sewers. Comparable as a German no-dig rehabilitation technology specialist serving municipal and industrial customers, though focused on a different liner technology.

Others

• IKT – Institute for Underground Infrastructure gGmbH: German independent testing and research institute for sewer and underground infrastructure. Not a direct competitor but closely adjacent — referenced in the company's IKT Warentest 'good' rating and a key ecosystem validator for German trenchless rehabilitation quality standards.

Regional players

• Kanalsanierung Fritz Herrmann GmbH & Co. KG: German trenchless sewer rehabilitation contractor based in the south/center of Germany. Comparable in trenchless methods offered (CIPP, robotic repair) but primarily serves different regional markets than Rohrsanierung Jensen's northern German footprint.
