Pipe Rehabilitation with CIPP Liner (Cured in Place Pipe)

Pipe Rehabilitation with CIPP Liner (Cured in Place Pipe)

Structural reinforcement without replacing the pipe

Servilar provides pipe rehabilitation using the CIPP (Cured in Place Pipe) method — an advanced trenchless technology that restores damaged or leaking pipelines without excavation or full replacement.
The process involves inserting a flexible liner impregnated with epoxy or polyester resin into the existing pipe. Once in place, it’s cured with hot air, steam, or UV light, forming a new, self-supporting pipe inside the old one.

This is the ideal solution for cracked, deformed, or leaking pipes, especially in difficult-to-reach locations such as underground systems, vertical stacks, or old building networks.

How the CIPP process works

1. Video inspection: A detailed inspection is performed to assess the condition of the pipe and determine its exact length and diameter.

2. Mechanical cleaning: The line is cleaned using high-pressure water jets to remove grease, debris, and mineral buildup.

3. Liner preparation and insertion: A flexible liner is saturated with resin and inserted into the pipe using air inversion or a guiding cable.

4. Resin curing: The liner is cured in place, hardening and forming a continuous, watertight inner wall.

5. Final verification: A post-installation video inspection confirms the quality and structural integrity of the new lining.

The result is a joint-free, leak-proof, structurally reinforced pipe, with a service life comparable to a brand-new installation.

Advantages of the CIPP system

• Full structural reinforcement of the existing pipe

• No digging or demolition required

• Reduced cost and downtime compared to replacement

• Suitable for long runs and large diameters

• Guaranteed watertightness with no infiltration

• High mechanical and chemical resistance

• Compliant with European standards EN 13566 and EN 13508-2

The CIPP method is widely used in urban infrastructure, condominiums, and industrial facilities, and is recognized as one of the most reliable and durable pipe rehabilitation techniques available today.

When to choose CIPP

The CIPP liner is recommended when pipes show major structural damage, longitudinal cracks, or partially collapsed sections.
It’s also the best option when repeated infiltration or leakage occurs and traditional replacement would involve complex or expensive construction work.

If the pipe is still structurally sound and only shows internal corrosion or wear, epoxy brushing or spraying may be sufficient.
That’s why Servilar always performs a detailed video inspection before deciding which rehabilitation method is most suitable and cost-effective for each case.
