Pipes play a crucial role in the operation of wastewater, drinking water and gas networks. However, over time, they can become subject to wear and tear, cracks, blockages and even ruptures. These problems can lead to leaks, flooding, unpleasant odors and health hazards. There are two main ways of dealing with them: complete pipe replacement or lining.
Replacement requires the removal and replacement of the damaged section, often involving costly and time-consuming work. In contrast, lining repairs the pipe from the inside out with a resinous coating, offering a quick, economical and less invasive solution.

Understanding the basics: Pipe lining and replacement
This article aims to shed light on the differences between lining and pipe replacement, two key strategies for rehabilitating deteriorated drains. We'll assess the advantages and disadvantages of each method, to guide you in making the most appropriate choice for your situation.
What is pipe lining?
Pipe lining is a minimally invasive renovation process involving the insertion of a new coating inside the existing pipe. The liner is made of a polymer resin which, once cured, creates a tough, waterproof layer. This technique is perfect for consolidating pipes, repairing breaches and preventing new blockages.
The main difference between resin spray lining, which uses robotized equipment to coat the inner walls with resin, and liner insertion lining, where a resin-coated glass fiber liner is inserted and expanded by pressure in the duct.
What does a complete pipe replacement entail?
Complete pipe replacement is a more traditional method and involves physically removing the damaged section and replacing it with a new one. This technique can be quite invasive, expensive and time-consuming, often involving significant excavation and renovation work.
It is typically considered when the damage is too extensive for a liner repair, or when a change in pipe diameter or shape is required.
Advantages and disadvantages of each method
The table below highlights the significant advantages and disadvantages of each approach:
Lining offers many advantages over complete replacement, particularly in terms of cost, efficiency and durability. However, lining may not always be feasible, and in some cases replacement may be necessary, particularly when ducts are significantly damaged or require structural modification. It is advisable to consult an expert who will be able to direct you towards the most suitable option for your specific situation.
Decision factors: When lining takes precedence over replacement
In this section, we detail the key factors influencing the decision between pipe lining and pipe replacement. These include the current condition of the pipe, environmental and logistical impacts, and economic considerations. Taking these aspects into account is crucial to choosing the best option for your needs.
Pipe condition analysis
The condition of the pipe is the first criterion to be assessed. Lining may not be feasible if the pipe is excessively damaged or deformed. A video inspection can be used to analyze pipe damage, shape, diameter and material. For minor problems such as cracks, leaks or blockages, lining is often an excellent solution. However, in the case of broken, crushed or deflected pipes, replacement is usually unavoidable.
Environmental and logistical considerations
The second factor concerns the environmental and logistical impact. Lining, which is less invasive, avoids the digging of deep trenches and preserves existing infrastructures, thus limiting nuisance to the environment, residents and traffic. What's more, this method produces less waste and CO2 emissions. Replacement, however, may be more appropriate for route modifications or in difficult-to-access areas.
Economics: long-term costs and benefits
The final factor to consider is the economics of the repair. Lining, which is generally less expensive, saves on earthworks, the purchase of new materials and labour. Faster implementation also reduces costs and inconvenience. With superior durability thanks to corrosion protection and structural reinforcement, lining offers excellent value for money. Nevertheless, replacement may be more economical for pipes that are severely damaged or require a change in size or configuration.
Case studies and testimonials
This section presents concrete case studies and testimonials relating to pipe lining and pipe replacement. Here you'll discover specific examples and feedback from customers and experts, illustrating the benefits and limitations of each technique.
Successful pipe lining scenarios
Pipe lining has effectively solved many problems associated with damaged pipes, avoiding major works and ensuring a lasting repair. Here are some significant examples:
-
In Nice, a hotel entrusted Docteur Canalisation with the renovation of its old cast-iron and stoneware sewage system. Thanks to the lining, leaks and infiltrations were repaired without disrupting business or damaging floors and walls, improving comfort and reducing maintenance costs.
-
A Cannes condominium faced with frequent blockages and unpleasant odors in its wastewater pipes saw a marked improvement after a resin lining, eliminating blockages and odors while increasing the flow of water.
-
In Menton, France, subsidence had ruptured an underground gas pipeline. Rather than digging it up, an insertion liner with a fiberglass sheath enabled the pipe to be repaired quickly and without environmental risk.
Bodies where replacement was unavoidable
There are situations where lining is not enough and pipe replacement becomes necessary. Here are some cases where replacement was the only option:
-
In Marseille, a house had to replace a lead pipe after water damage, thereby eliminating a health risk and improving water flow and pressure.
-
After a landslide, a school in Fréjus had to replace its rainwater drainage pipes to restore normal water flow and reinforce the pipes against ground stress.
-
Faced with the corrosion of its steam pipes, a plant in Sofia Antipolis opted to replace them with stainless steel pipes, which are more resistant to corrosion and optimize routing to reduce energy losses.

Conclusion
If you're faced with damaged pipes and you're wondering about the most appropriate method of repair, you should know that you have two main options: pipe lining and pipe replacement. Each of these techniques has its own advantages and disadvantages, which vary according to the situation.
Lining is an innovative, non-destructive method of renewing the interior of existing pipes. This approach is generally more economical, faster, less disruptive and offers a longer service life than conventional replacement.
As for replacement, this is a more traditional solution that involves removing the damaged pipe and replacing it with a new one. This technique is preferable when the damage is too extensive or requires modification of the pipe configuration.
To determine which method is best suited to your case, it's crucial to take into account a number of factors, such as the current state of the pipeline, and environmental, logistical and economic constraints. The concrete examples and testimonials we have shared can also help guide you, highlighting the strengths and limitations of each option. Whatever your choice, the assistance of a qualified expert is recommended to advise you effectively and ensure implementation in line with professional standards.
