Seamless repair. Without disruption.

Spraycoating is a cutting-edge method to restore drain systems of various diameters back to like-new condition. Over time, systems made of materials like cast iron (which tends to rust), Eternit, PVC, or PE (which often leak at joints or bends) begin to fail. With spraycoating, we can fully restore these systems to watertight condition—with a lifespan of up to 50 years and a 10-year warranty—without breaking floors, walls, or causing any disruption to residents.

We use a high-performance, two-component resin that is DiBt-certified and known for its durability. The coating is applied in multiple layers depending on the pipe’s diameter and material. This results in minimal downtime and a completely internal renovation process, eliminating the need for invasive construction work. However, the success of the renovation depends on full cooperation from residents—in particular, they must not use the plumbing while work is underway.

Pipe systems can be put back into operation within 1 day in most cases, so disruption is absolutely minimal. Moreover, demolition is absolutely unnecessary, seeing as we apply the coating on the inside of the pipe system utilizing existing exit and entry points.

How Spraycoating Is Applied

1. The pipes are mechanically milled until the original material is exposed.
2. Hot water flushing and brushing is used to clean and degrease the pipes.
3. Hot air is used to fully dry the system—the pipes must remain dry throughout the process.
4. A second inspection ensures all pipes are clean and completely dry.
5. The first layer of coating is applied.
6. Subsequent layers are added after each drying phase—this is completed within the same day.
7. A final inspection and delivery recording is made.
8. The pipes are cleared for use.

The pipes are ready to use again that same day.

Important Considerations

• The renovation team must have access to the pipes, both inside and outside the property. In apartment buildings, we can access vertical stacks via the roof if needed.
• We will need access to water and electricity during the process.
• Residents cannot use their plumbing systems while the work is ongoing.
• Our machinery needs to be parked close to the work area for efficiency.

As with all our renovation solutions, we can only offer a warranty when the cleaning is performed by us or a qualified professional. These methods require specialized cleaning to ensure long-term durability.
