Pipe Rehabilitation in Condominiums and Old Buildings

Pipe Rehabilitation in Condominiums and Old Buildings

Modern solutions for old networks without demolition

In old buildings and condominiums, drainage and water systems often suffer from natural wear, corrosion, and hidden leaks that lead to infiltration and structural damage.
Servilar provides trenchless pipe rehabilitation, using methods such as internal epoxy coating, brushing, spraying, and CIPP liner installation — all performed through existing access points, without breaking walls or replacing entire systems.

The result is a new watertight pipe inside the old one, stronger, smoother, and ready to serve for decades.

Complete diagnostic with video inspection

Before any intervention, our team performs a detailed video inspection to identify cracks, corrosion, and defective joints in vertical stacks and horizontal lines.
This analysis allows us to determine the most suitable rehabilitation method — whether epoxy, CIPP, or localized repair — according to the type of damage and the overall condition of the network.
We provide technical reports and video documentation, which are also useful for building administrators and insurance companies.

In Lisbon’s older buildings, it’s common to find stoneware (grés) and concrete sewer lines, especially in original waste stacks and basement drains.
These materials, widely used until the mid-20th century, are still functioning in many historic and central districts.
Most of these systems consist of pipes with diameters between 100 and 125 mm, which remain structurally stable but show internal wear, fine cracks, and joint infiltration.
In such cases, internal rehabilitation with epoxy coating or CIPP lining is an excellent solution — it restores watertightness and extends the lifespan of the network without full replacement.

Methods applied in buildings and condominiums

• Internal epoxy coating (brushing or spraying) to renew the inner surface and stop leaks;

• CIPP relining, creating a new structural layer inside deteriorated pipes;

• Localized repairs for small leaks or cracks where the rest of the network is still sound;

• Mechanical cleaning, using rotating brushes and high-pressure water to remove scale and deposits.

These techniques are particularly effective in wastewater, stormwater, and vertical stack systems, which are common in older residential buildings.

Benefits for condominiums

• No demolition or interruption of building use;

• Quick, quiet work — ideal for occupied buildings;

• Increased durability and safety of the network;

• Elimination of leaks, odors, and infiltration;

• Compliance with European standards EN 13508-2 and EN 13566.

An investment that protects your building’s value

Pipe rehabilitation is more than a repair — it’s an invisible structural upgrade that preserves the building’s value and prevents future costly works.
With advanced technology and specialized technicians, Servilar guarantees clean, durable, and certified results. We collaborate with the Revipox technical team on large-scale pipe rehabilitation projects, ensuring certified and technologically advanced solutions.
