Pipe lining for individuals: complete guide and prices

Pipe lining represents a major innovation in the world of pipe rehabilitation. Without requiring major works, this technique is increasingly popular in France. It uses an epoxy resin which, when hardening, creates a new pipe inside the old one. This article offers you a detailed guide on pipe lining for individuals, covering its principle, its benefits and the related costs.

Let’s dive into the phases of lining: from preliminary assessment by video inspection to cleaning and then to actual repair. You will learn how lining proves to be an economical and discreet alternative to conventional methods. Follow us to understand how this advanced technology can revive your wastewater and stormwater pipes, while protecting your property.

Understanding Pipe Lining: An Effective Rehabilitation Solution

What is pipe lining?

Pipe lining represents an innovative renovation technique for sewerage networks, avoiding excavations. This method involves the introduction of a sheath, made of fiberglass or felt, saturated with epoxy or polyester resin, into the existing pipe. After insertion, the resin solidifies, creating a new, robust conduit inside the old one. This innovation restores structural integrity without requiring major earthworks.

It is particularly effective for small diameter pipes, which are often inaccessible, and is suitable for a variety of materials, such as PVC, reinforced concrete, and steel. Its use extends to the repair of damage due to soil settlement, corrosion, cracks and even the insulation of pipes containing asbestos.

Initially developed in the 1970s in London for Thames Water Company, this technology has undergone remarkable evolution, spreading widely to become a preferred solution for rapid and discreet rehabilitation of sanitation infrastructures, both in urban and industrial environments.

Benefits of Lining for Individuals

Adopting liners offers multiple benefits to property owners. From an economic standpoint, this method reduces the costs associated with excavation and landscape restoration. It is also quick, drastically reducing the time required for a repair, which reduces disruption to residents.

A pipe renovated by lining can offer exceptional durability, reaching up to 50 years of efficiency. This process is also beneficial for the environment by minimizing the ecological impact linked to traditional works. In addition, it improves water quality by preventing contamination from damaged pipes.

Residents also benefit from a significant reduction in the risk of accidents caused by leaks or pipe failures. This method thus reinforces the safety and reliability of their sanitation system.

The different lining techniques

Pipe lining is available in different techniques, adapted to specific needs. For localized repairs, partial sheath lining is ideal. Conversely, continuous sheath lining by reversion is perfectly suited to the renovation of long sections in one intervention.

Structuring resin jet lining, suitable for treating minor cracks, can be applied over the entire length of the pipeline, including connections. This method offers the flexibility needed to rehabilitate complex sanitation networks without major disruption.

Technological advances have made it possible to develop more sophisticated techniques, such as continuous lining in fiberglass or resin-impregnated felt. These solutions guarantee a uniform and durable repair, even in pipes with curves, avoiding the formation of folds.

The pipe lining process: how does it work?

Step 1: Diagnosis and preliminary inspection by camera

An accurate diagnosis is essential before any intervention. Camera inspection, a crucial initial step, uses advanced technologies to explore the inside of the pipes. This makes it possible to identify anomalies, such as cracks and obstructions.

These state-of-the-art cameras help to assess the condition of the pipelines without damage. This comprehensive inspection is the key to effective lining planning, by identifying sections requiring repairs.

The inspection report provides a precise overview, crucial for the preparatory phase of the lining.

Step 2: Prepare and clean the pipes

Preparation begins with a thorough cleaning, which is crucial to remove debris and other obstructions. This ensures optimal adhesion of the resin.

High-pressure cleaning is one of the techniques used to clean and dry pipes. This step ideally prepares the pipes for lining by ensuring an adequate internal surface.

This meticulous cleaning ensures the quality and longevity of the future repair.

Step 3: Installing the liner and curing

The installation step involves inserting a resin-impregnated sheath into the pipe. This sheath, once in place, is hardened to create a new, solid internal layer.

The curing process can be accelerated by the use of steam or hot water. This forms a robust structure that rehabilitates the pipeline.

This reinforcement not only repairs but also improves the durability of the structure.

Step 4: Final inspection and validation of the work carried out

Once the resin has cured, a final inspection is essential to confirm the quality of the lining. Further camera inspections certify successful application and rehabilitation of the pipes.

This final check ensures compliance with quality and safety standards. It also confirms that the pipelines are ready for use.

Costs and factors influencing the price of pipeline lining

Elements impacting the price of the lining

There are several key factors that affect the cost of pipe lining. The size and length of the pipes are crucial, causing prices to fluctuate between €100 and €300 per metre. Naturally, the larger and wider the pipe, the more expensive it will be to line it.

As for materials, polyester, epoxy, and polyurethane are frequently used, significantly influencing the price. Among them, epoxy, praised for its resistance, tends to be the most expensive.

The complexity of the project also influences the price. Access to the conduits and the presence of obstacles, such as vegetation or constructions, can increase the cost. Sometimes, working under structures increases the costs significantly.

Pricing Estimates: What to Expect for a Lining Project?

The length to be treated is decisive for establishing an estimate. Let's take the example of a 10 m pipeline: the costs vary from 1,000 to 3,000 euros, excluding taxes.

For liner with sheathing on a diameter of 100 mm, expect an average price between 250 and 350 euros per meter. For comparison, spray liner fluctuates between 150 and 250 euros.

It is crucial to request several quotes for a suitable and precise estimate. These must take into account the uniqueness of the project and the price variations depending on the expertise and location of the professionals.

Conclusion

Pipe lining is an effective renovation method that offers a multitude of advantages. Thanks to this modern technique, it is possible to significantly extend the life of your pipes. This process also avoids the disadvantages associated with traditional repair work.

With transparent cost planning and fast execution, lining is the perfect solution for homeowners looking to protect their homes. Don’t delay, get information from qualified professionals. Consider lining as a reliable strategy to ensure the longevity of your sanitation systems.
