CIPP rehabilitation of branch pipes

CIPP rehabilitation of branch pipes

CIPP rehabilitation of branch pipes allows the restoration of pipe sections connecting fixtures to the main drainage system, without opening floors or walls.

Branch pipes are often responsible for localized leaks, odors, and infiltration, especially in kitchens, bathrooms, and technical areas. When they show deterioration or structural damage, liner rehabilitation provides an effective and long-lasting solution.

Common problems in branch pipes

In branch lines, it is common to find:

• cracks in PVC or clay pipes

• joints losing watertightness

• defective connections between fixtures and the system

• poorly executed or intruding connections

• deposits caused by internal irregularities

Because these are shorter sections with multiple connections, problems tend to be localized but can lead to direct infiltration into floors, walls, or ceilings below.

How CIPP rehabilitation works

The process involves inserting a fiberglass liner impregnated with resin into the branch pipe, which is then cured using UV/LED light, forming a continuous new pipe.

After curing, the new structure:

• eliminates cracks and leakage points

• reinforces the pipe integrity

• creates a smooth internal surface

• improves flow conditions

The intervention is carried out through existing access points such as traps, inspection openings, or by temporarily removing sanitary fixtures, avoiding invasive works.

Durability and structural solution

CIPP rehabilitation of branch pipes allows the system to gain an extended service life of 40 to 50 years, creating a new pipe with high mechanical and chemical resistance.

It is a structural solution, recommended when the pipe shows significant wear or when a long-term repair is required.

When this solution is suitable

CIPP rehabilitation is recommended when:

• recurring leaks are present in localized areas

• the pipe shows cracks or deterioration

• a long-term, stable solution is required

• opening floors or walls is not desirable

In cases of minor leaks limited to joints or connections, non-structural methods such as epoxy lining may be sufficient. However, when structural integrity is compromised, CIPP is the appropriate solution.

Advantages of no-demolition intervention

Applying CIPP in branch pipes allows:

• avoiding demolition in kitchens and bathrooms

• reducing intervention time

• minimizing disruption for occupants

• addressing the affected section directly

• extending the lifespan of the installation

This approach is particularly useful in occupied properties, where traditional repairs would be more complex.

Preparation and inspection

Before rehabilitation, it is essential to carry out:

• CCTV inspection to locate defects

• cleaning and clearing of the pipe

• verification of existing connections

• assessment of access conditions

Proper preparation ensures the quality of the installation and the long-term performance of the new pipe.

An effective solution for branch pipe repair without demolition

CIPP rehabilitation of branch pipes provides a technical and durable way to resolve localized problems without invasive works. It is increasingly used to repair pipes in kitchens, bathrooms, and other sensitive areas.

If you are experiencing signs of leakage or infiltration, we can assess the branch pipe and recommend the most suitable solution.
