Sewer rehabilitation: Modern trenchless rehabilitation for intact sewers in Bonn and the Rhein-Sieg district

Leaky, damaged, or dilapidated sewer lines are a serious problem that can lead to groundwater contamination, backups, and costly excavation work. Blix Drain Cleaning from Bad Honnef, in close partnership with the specialist Gerdes Sewer Rehabilitation from Königswinter, offers professional solutions for the rehabilitation of your sewer lines – often completely without excavation!

Together we ensure tight and stable wastewater pipes in Bonn, Bad Honnef, Siegburg, Königswinter, Hennef, Asbach, Neustadt (Wied) and the entire Rhein-Sieg district and Westerwald.

Renovation should be considered in the following cases:

• Root intrusion into pipe joints
• Cracks, breaks or deformations of the pipe
• Leaks and infiltrating groundwater
• Deposits caused by corrosion and material loss
• The legally required leak test (DIN 1986-30), which detects defects

Thanks to state-of-the-art technology, leaking pipes no longer necessarily need to be excavated. In our partnership, we rely on these proven methods:

During relining, a resin-impregnated tube (a so-called "liner") is inserted into the existing pipe and cured there under pressure or with hot air. This creates a new, smooth-walled and leak-proof "pipe within a pipe." This is an extremely gentle and cost-effective method.

A further development of relining for larger damages. Special fabric sleeves are inserted and pressed against the inner wall of the old pipe, where they harden and form a completely new, structurally sound inner pipe layer.

The inside of the pipe is sprayed with a cement or polymer mortar mixture. This protects against corrosion, smooths the surface, and seals small cracks. Ideal for concrete sewer pipes.

We are a proud partner of:
