Pipe Lining Reviews in 2024? Advantages and Disadvantages of Pipe Lining in 2024

The pipe lining technique offers an innovative solution for repairing damaged pipes without requiring their complete replacement. It consists of inserting a flexible sheath coated with resin inside the existing pipes. This sheath will then harden, thus creating a new resistant and waterproof coating. This makes it possible to refurbish wastewater, rainwater or drinking water networks, avoiding major and costly works.

What are the benefits and drawbacks of pipe lining from 2024? Is this method suitable for all situations? How much does pipe lining cost per linear meter?

The purpose of this article is to share our opinion on this revolutionary method and to detail the foundations, phases and specificities of pipe lining.

What is Pipe Lining? Definition and Process

Definition of pipeline lining

Pipe lining is a rehabilitation method that avoids the total replacement of damaged pipes. It consists of inserting a flexible resin-coated sheath into the existing pipe. Once hardened, this sheath creates a new solid and waterproof conduit. This technique is ideal for restoring sanitation, rainwater drainage or drinking water distribution systems, without requiring major or expensive work.

Technical process of lining

The process is broken down into several key steps:

• Detailed inspection of the pipes with a camera to locate damage and assess the condition of the pipe.
• Intensive cleaning and preparation by high-pressure hydro-cleaning or biological methods to remove debris and ensure good adhesion of the sheath.
• Installation of the resin sheath in the pipe, using inversion or traction techniques, and expansion of the sheath so that it fits perfectly in the conduit.
• Polymerization of the resin, activated by heat or a catalyst agent, to solidify the sheath.
• Quality control of the coating by camera and surface finishing if necessary.

Lining Types Available in 2024

Various lining options will be available in 2024, adapted to various needs and constraints:

• Resin spray lining uses a robot to apply epoxy resin to the inside of small pipes (40 to 200 mm diameter) over short sections (1 to 15 m).
• Continuous lining, or liner, uses a fiberglass sheath impregnated with polyester resin for larger diameter pipes (100 to 1200 mm) and over long distances (up to 300 m).
• Spray lining, or partial lining, involves the direct application of epoxy resin to damaged areas using a gun. This method is suitable for all sizes of pipes and allows for a very targeted repair.

Benefits of Pipe Lining in 2024

Cost and time savings

The pipe lining technique offers significant savings in terms of costs and time compared to traditional repair methods. Without requiring excavation or dismantling of the pipes, it considerably reduces labor and material costs. In addition, the lining is implemented in a few hours, thus minimizing intervention periods.

Sustainable and environmentally friendly solutions

This method is a sustainable and environmentally friendly solution. Pipe lining prevents corrosion, scale, leaks and blockages, thereby increasing the longevity of the pipes. By avoiding major excavation work, this technique also reduces the impact on the environment.

Advanced technologies and reliable results

Using cutting-edge technologies, pipe lining ensures reliable results. Thanks to the use of high-end materials such as epoxy resin or fiberglass, the repair guarantees watertightness and resistance. The use of video inspection in the process makes it possible to supervise the operation and ensure the quality of the result.

Less disruption to daily life

This technique reduces inconveniences in daily life. The lining process avoids water cuts and traffic diversions, limiting inconveniences for residents and users. In addition, it reduces the noise of water in the pipes, thus improving the acoustic comfort of homes.

Disadvantages and limitations of pipeline lining in 2024

High initial cost and availability of experts

Pipe lining is distinguished by its high initial cost compared to traditional repair methods. The price of this process varies depending on the material used, the length of the pipe to be repaired and the choice of professional.

This method can be expensive, ranging from 100 to 300 euros per linear meter. It is therefore crucial to carry out an accurate price comparison before selecting an expert.

Furthermore, pipe lining requires specific know-how and special equipment, which limits its accessibility to certain specialists. Finding a competent and experienced professional can therefore be difficult, leading to prolonged waits or complications in obtaining an appointment.

Technical limitations depending on the condition of the pipes

The feasibility of pipe lining depends heavily on the condition of the pipes. Some major deterioration or significant deformation may make this method inapplicable, sometimes requiring a complete overhaul or replacement.

Pipes with large holes or undergoing advanced corrosion, thus losing their structural strength, are not suitable for lining. This process is also constrained by the diameter and shape of the pipes, requiring a minimum diameter of 40 mm for the insertion of the resin sheath.

In addition, carrying out the lining on pipes with bends, narrowings or branches can be complex, as these characteristics can hinder the installation of the sheath or its correct expansion.

Possible complications during application

The application of pipe lining is not without risks and can cause complications if not carried out correctly. Incorrect positioning of the sheath, imprecise dosage of the resin or non-optimal curing can cause leaks, detachments or cracks. It is therefore essential to call upon a qualified specialist and carry out a video inspection of the result.

The material used for the liner, such as epoxy resin, can be toxic if mishandled, releasing harmful fumes or causing skin and eye irritation. Compliance with safety standards and the use of personal protective equipment are imperative when applying the liner.

Conclusion

Pipe lining represents an innovative and efficient solution for repairing damaged pipes without requiring their replacement. This method offers several significant advantages, such as reduced costs and time required for the intervention, high durability, unfailing reliability, as well as an environmentally friendly approach.

This technique is suitable for various scenarios, depending on characteristics such as the diameter, shape and general condition of the ducts. However, it also has disadvantages, including a significant initial investment, the scarcity of qualified specialists, certain application limitations and the risk of complications during the process.

To take full advantage of pipe lining in the renovation of your drainage systems, it is recommended to consult a certified and experienced expert. They will be able to guide you towards the solution best suited to your requirements and your budget.
