What is modern sewer rehabilitation?

Modern sewer rehabilitation does not require extensive excavation work. Instead, defective pipes are repaired from the inside—a process known as "trenchless" or "no-dig" rehabilitation. This is always based on aprofessional TV inspectionto analyze the damage.

The best-known method is hose lining: a textile hose impregnated with synthetic resin is inserted into the damaged pipe and cured on site. Before renovation, we carry out athorough pipe cleaning.

We use short liners orrobotic rehabilitationfor localized damage.Spray coatingprovides additional corrosion protection. Special processes are used forindustrial plants.

Our sewer rehabilitation methods in detail

Depending on the type of damage—as determined byTV inspection—we select the optimal repair method.

Pipe liner

Trenchless rehabilitation by pulling in a resin-impregnated hose. Forms a new, seamless pipe wall in the existing sewer.

Short liner rehabilitation

Selective repair of individual damaged areas using our robot technology. Ideal for local damage such as cracks or misaligned joints.

Frequently asked questions about sewer rehabilitation

Everything you need to know about trenchless rehabilitation methods,robot technology, andspray coating.

What is trenchless sewer rehabilitation?

In trenchless rehabilitation, defective pipes are repaired from the inside without digging up the ground. This saves costs and time and protects gardens, roads, and buildings. A TV inspection always forms the basis for this process.

How does sewer rehabilitation work?

First, we carry out a TV inspection. Then we thoroughly clean the pipes. Depending on the damage, we choose between inliners, short liners with robot technology, or spray coating. Finally, we check for leaks.

How long does an inliner rehabilitation last?

Modern inliner systems have a service life of over 50 years. We provide a 20-year warranty on our renovations.

How much does sewer rehabilitation cost?

The costs depend on the length, diameter, and extent of the damage. Trenchless methods are usually 30-50% cheaper than completely replacing the pipe with excavation.

What role does spray coating play in renovation?

Spray coating is ideal as supplementary corrosion protection or for small, superficial damage. For larger damage, we recommend inliner or short liner methods.

Do you also offer refurbishment for industrial plants?

Yes, our industrial service specializes in large pipe cross-sections and the specific requirements of production facilities.
