What is Modern Sewer Rehabilitation?

Modern sewer rehabilitation eliminates the need for extensive excavation work. Instead, damaged pipes are repaired from the inside—a process known as “trenchless” or “no-dig” rehabilitation. This process always begins with aprofessional CCTV inspectionto assess the damage.

The most well-known method is CIPP lining: A textile hose saturated with synthetic resin is inserted into the damaged pipeline and cured on-site. Prior to rehabilitation, we perform a thorough pipe cleaning.

For localized damage, we utilize short liners or robotic rehabilitation. Spray coating provides supplementary corrosion protection. For industrial facilities, specialized procedures are employed.

Our Sewer Rehabilitation Methods in Detail

Depending on the type of damage – identified through TV inspection – we select the optimal rehabilitation method.

Liner

Trenchless rehabilitation by inserting a resin-impregnated hose. This forms a new, seamless pipe wall within the existing sewer.

Short Liner Rehabilitation

Localized repair of individual damaged areas using our robotics technology. Ideal for local damage such as cracks or joint displacement.

Spray Coating

Innovative internal coating for additional corrosion protection and sealing minor damage.

Leak test

Certified inspection according to DIN EN 1610 with TV inspection. Provides proof of successful rehabilitation for authorities and owners.

Frequently asked questions about sewer rehabilitation

Alles Wichtige rund um grabenlose Sanierungsverfahren, Robotertechnik 

und Spray Coating.

What is trenchless sewer rehabilitation?

In trenchless rehabilitation, defective pipelines are repaired from within without excavating the ground. This saves costs, time, and protects gardens, roads, and buildings. A TV inspection always forms the basis.

How is a sewer rehabilitation carried out?

First, we conduct a TV inspection. This is followed by a thorough pipe cleaning. Depending on the damage, we select CIPP liners, short liners with robotics, or spray coating. Finally, we test for watertightness.

What is the lifespan of a CIPP liner rehabilitation?

Moderne Inliner-Systeme haben eine Lebensdauer von über 50 Jahren. Wir geben auf unsere Sanierungen eine Gewährleistung von 20 Jahren.

What is the cost of sewer rehabilitation?

The costs depend on the length, diameter, and extent of the damage. Trenchless methods are typically 30-50% more cost-effective than a complete pipe replacement involving excavation.

What role does spray coating play in rehabilitation?

Spray coating is ideal as supplementary corrosion protection or for minor, superficial damage. For more extensive damage, we recommend CIPP liner or short liner procedures.

Do you also offer rehabilitation for industrial facilities?

Yes, our Industrial Service specializes in large pipe diameters and the specific requirements of production facilities.
