Trenchless Pipe Rehabilitation in Porto

Trenchless Pipe Rehabilitation in Porto

Replacing old or damaged pipes in residential or commercial buildings in Porto can be expensive, time-consuming, and highly disruptive. At Servilar, we offer a cleaner, faster, and smarter alternative: trenchless pipe rehabilitation using CIPP (Cured-in-Place Pipe) technology. This method creates a new pipe inside the old one — without breaking walls, opening floors, or digging trenches.

It’s the ideal solution for sewer and stormwater lines in apartment buildings, hotels, clinics, schools, and commercial zones throughout Porto — especially in dense urban areas such as Boavista, Cedofeita, Foz, Bonfim, and Campanhã.

Step-by-step – modern and reliable technology

The process begins with a detailed video inspection, using HD cameras to assess the interior condition of the pipe system. Then, we perform a technical cleaning using rotary brushes and robotic tools, removing grease, scale, roots, and other debris.

Next, a textile liner saturated with epoxy resin is inserted into the host pipe, either by inversion or pull-in-place. The resin is cured using hot water, steam, or — in advanced applications — UV light curing, which offers faster, stronger, and more precise results. With this technology, the newly lined pipe can often be returned to service within a few hours, with no dust, demolition, or structural disruption.

When is trenchless pipe relining recommended?

• Persistent leaks in sewer stacks or vertical lines

• Repeated blockages even after cleaning

• Unpleasant sewer odors and noise in the drains

• Infiltrations affecting ceilings or common areas

• Replacement of aging piping without tearing up floors or walls

Key benefits for buildings and infrastructure in Porto
