Rainer Kiel Kanalsanierung

What Rainer Kiel Kanalsanierung does

Rainer Kiel Kanalsanierung GmbH is a German specialty trade company founded in 1988 in Blomberg that delivers trenchless (grabenlose) rehabilitation of sewer and canal systems across Germany. Its service portfolio spans main-channel renovation, partial repairs, house-connection rehabilitation, large-profile structure renovation, shaft (Schachtbauwerk) rehabilitation, separator system (Abscheider) renovation, and property drainage systems, served through a four-segment customer base — municipal/communal clients, industrial operators, engineering offices, and private households. The company operates exclusively on the German market through six physical locations (Blomberg HQ plus Berlin, Hamburg, Kassel, Münster, Würzburg), with mobile field teams of 2-4 employees deployed nationwide on Monday-Thursday schedules.

The company's technical stack centers on trenchless rehabilitation methods rather than open-cut excavation. Core methods include Schlauchlining (CIPP — cured-in-place pipe lining using resin-impregnated polyester needle felt or fiberglass liners, cured thermally or via UV light, applied across DN 100 to DN 1500 diameters), Kurzrohrrelining (factory pipe-module insertion for walkable profiles), KA-TE remote-controlled robotic repair systems for partial damages (DN 200 to DN 700), Kurzliner point repairs with cold-cured silicate resin fiberglass patches, and Quick-Lock stainless-steel internal sleeves (DN 150 to DN 1600). Supporting technologies include HD camera inspection systems and UV light chain curing rigs. All major German sector certifications are held — DEKRA, VSB, DWA, TÜV Nord WHG, RAL-GZ 961, VDRK RKI-Meisterbetrieb — plus City of Hamburg certified specialist status for property drainage.

Revenue is generated through project-based professional services contracts, with custom quotations based on scope, pipe dimension, damage type, and site conditions rather than published rate cards. Pricing is multi-year for public-sector framework agreements and includes consulting/planning, inspection, rehabilitation, and ongoing maintenance streams. The go-to-market is direct enterprise field sales — no resellers, marketplaces, or digital channels — augmented by an educational YouTube presence, industry association memberships (including German Water Partnership), and an internal training-to-master-craftsman apprenticeship pipeline managed by two authorized managing directors, Katrin Kiene and Malte Nowak. The company is privately held as a GmbH with no disclosed external investors or M&A activity.

Products and services

• Schlauchlining (CIPP Pipe Lining) Trenchless pipe renovation using resin-impregnated polyester needle felt or fiberglass liners installed by inversion or pull-in methods and cured with heat or UV light. Suitable for nominal widths DN 100 to DN 1500, using epoxy, UP, or vinyl ester resins. Used for main canal, branch, and large-diameter pipe rehabilitation where excavation is undesirable.
• Kurzrohrrelining Trenchless installation of factory-quality-assured pipe modules inside existing canals using circular, oval, and special profiles up to walkable nominal widths. Modules are highly load-bearing, wear-resistant, and corrosion-resistant, providing structural renewal without excavation.
• Robotic Canal Repair (KA-TE Robot System) Remote-controlled KA-TE robot systems for partial pipe damage repair, including removal of protruding connections and obstacles, crack repair, epoxy resin injection for defective joints, and connection of damaged inlets using hat profile technology. Adaptable to pipe dimensions DN 200 to DN 700.
• Kurzliner (Short Liner) Point Repair Point defect repair using custom-made fiberglass fabric saturated with a three-component silicate-based resin, installed under camera observation at the damage site and cold-cured. Provides load-bearing, corrosion- and abrasion-resistant localized repair with short installation time.
• Quick-Lock Stainless Steel Sleeves Stainless steel internal sleeves for point damage affecting tightness and structural stability, applicable in circular profiles DN 150 to DN 1600. Particularly suited to industrial wastewater networks due to high chemical resistance.
• Large Profile Channel Renovation Individual renovation of large concrete and masonry wastewater structures using injection waterproofing, surface preparation, masonry joint repair, corrosion-resistant coatings with canal special mortars, stoneware linings, and GFRP pipe module relining.
