CIPP Lining — Internal Structural Rehabilitation with Epoxy Resin

CIPP technology for no-dig pipe rehabilitation

CIPP (Cured In Place Pipe) technology is one of the most advanced solutions for pipe rehabilitation, allowing the creation of a new pipe inside the existing one, without excavation or demolition.

This method is used in sewer and stormwater systems, both in buildings and buried infrastructure, and is a technically proven solution widely applied worldwide.

How CIPP technology works

The process involves installing a flexible liner, typically made of fiberglass and impregnated with resin, inside the existing pipe.

Once in place, the liner is cured using UV or LED light, forming a continuous new pipe fitted to the interior of the original pipeline.

The result is a structure that:

• creates a new pipe within the existing one

• eliminates cracks, infiltration, and material loss

• reinforces the structural integrity

• improves internal flow conditions

Materials used in rehabilitation

CIPP technology uses materials designed for durability and performance:

• fiberglass liners with high mechanical strength

• technical resins with chemical resistance

• controlled curing systems (UV/LED)

These materials allow the formation of a new pipe with structural behavior and long-term reliability.

UV/LED curing technology

The curing process is carried out using UV or LED equipment, allowing:

• controlled and monitored installation

• fast and efficient curing

• recording of execution parameters

• high-quality final result

LED technology, in particular, offers increased control and flexibility and is increasingly used in pipe rehabilitation.

Durability and performance

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

This solution is widely used in both public and private networks, with proven performance in different conditions.

Applications of CIPP technology

This method can be applied in various contexts, including:

• vertical sewer stacks

• branch connections

• buried pipelines

• stormwater drainage systems

As long as proper access and preparation are ensured, the process can be carried out in a controlled manner.

Advantages of CIPP rehabilitation

Using this technology allows:

• avoiding invasive works

• significantly reducing intervention time

• minimizing disruption to buildings and surroundings

• rehabilitating pipes without replacement

• achieving a long-lasting structural solution
