• In-house modernisation

Without chiselling and demolition work

➦ As an innovative and modern company, we clean, inspect and renovate pipelines and wastewater systems using the latest, recognised technology at the highest level, coupled with a high and always individual level of consulting expertise.

Using the spray coating process, we renew broken pipes in the shortest possible time.

➦ This is possible because we utilise the latest findings from research and science and use them to refurbish the inside of pipes.

Your advantage as a property owner or resident: After just a few hours, the damaged pipe is repaired – and you are protected from further damage in the long term.

In-house modernisation of a cast iron pipe:

Before the modernisation

The polyester coating lasts for at least 50 years!

With the Proline spray coating process, we are able to completely refurbish complicated pipe runs from a diameter of 40 mm.

➦ Procedure

1. inspection
We carry out a systematic inspection of the entire pipework using a camera.

2. documentation
The weak and damaged areas are documented and marked on the corresponding pipe plan.

3. spraying process
The dried pipes are then sprayed from the inside with liquid polyester plastic. This is cured in layers and forms a new, intact pipe in the composite.

4. final documentation
Once our work has been completed, final documentation is drawn up. This is also used to check whether all damage has been repaired.

We look forward to your enquiry!

➦ Advantages

You can remain in the building while the work is in progress. No moving of tenants, no covering of furniture or furnishings, no production stops – the work is organised in such a way that it can be carried out during ongoing operations.
