Understanding Pipe Lining: Fundamentals and Benefits

What is pipe lining?

Pipe lining is an innovative method for renovating sewerage networks without replacing damaged pipes. This technique involves inserting a new resinous layer inside the pipes, offering a solution that is both economical and ecological. It extends the life of the pipes while optimizing their functionality.

Benefits of Lining for Pipeline Rehabilitation

Adopting lining as a repair solution avoids destruction, the need to dig trenches and allows the activity to continue without interruption. This method effectively treats leaks, infiltrations, backflows and corrosion problems, thus reducing inconvenience, damage and health risks.

It guarantees flawless sealing of the conduits, using materials adapted to the required mechanical and chemical resistance, while being environmentally friendly by reducing water consumption, preventing soil contamination and minimizing waste.

Different techniques and materials used

Various techniques and materials are available for pipe lining, depending on the specifics of the network and the customer's needs. The most commonly used methods include:

• Resin spray coating: This modern technique involves spraying epoxy or polyester resin onto the internal walls using a robot. It is fast, flexible and suitable for diameters from 40 to 600 mm.
• Lining by sheathing: Consists of inserting a flexible tube coated with resin into the existing pipeline, this tube is then inflated and hardened using air, water or steam. This method is reliable, efficient and applicable for diameters from 100 to 1200 mm.

Preparation before starting

Assess the required skills and knowledge

Pipe lining requires precise technical expertise and a thorough understanding of regulatory standards. It is crucial to master the use of specific equipment, adhere to safety and quality standards, and know the different phases of pipeline rehabilitation.

Basic skills in plumbing, civil engineering and surveying are also required to work effectively on diverse and complex networks. Before starting, it is essential to assess your own level of skill and knowledge, and to train adequately.

Choosing the right equipment and materials

For a successful lining operation, selecting the appropriate equipment and quality materials is essential. It is important to choose equipment that is suitable for the dimensions and configuration of the pipes to be renovated. The selection of resistant, durable materials that ensure good adhesion and sealing is also crucial.

There are different types of resins and sheaths available on the market, each with specific characteristics and performances. It is therefore advisable to learn about each option and seek professional advice to make the best choice.

Understanding the regulations in force

Pipe lining is subject to strict standards, in accordance with the regulations in the sanitation sector. It is imperative to comply with the Environmental Code, the Public Health Code, the Construction and Housing Code, as well as the technical guidelines and specifications of the various players in the sector.

In order to protect yourself against possible fines and to guarantee a service that meets expectations, it is essential to be informed about current regulations and stay up to date on legislative and regulatory changes.

Build a solid business plan

Pipe lining offers significant market opportunities, driven by increased demand for the renovation of sewerage networks. This method, which is less expensive and more practical than total pipe replacement, is attracting a growing number of customers.

It is therefore crucial to develop a robust business plan, clearly defining objectives, resources and development strategies. An analysis of the market, competition, customer needs, financing options and communication strategy is necessary to succeed.

Training and practice to become a professional

Training Options Available for Pipe Lining

Pipe lining training offers several paths, adapted to the initial level and objectives of each candidate. Options include initial training offered by specialized establishments such as the National Center for Training in Water Professions (CNFME) or the Institute for Training and Research on Health and Social Organizations (IFROSS). For those looking for continuing education, private or public organizations such as Docteur Canalisation or Curatec offer modules focused on different lining techniques and materials.

Learning can be enriched by practical training carried out on real construction sites or within platforms dedicated to teaching.

Obtain the necessary certification

Certification represents a criterion of quality and commitment for professionals in pipeline lining. It validates the mastery of essential skills to carry out work in accordance with the standards and best practices of the sector.

In France, the NF390 certification, awarded by the Centre Scientifique et Technique du Bâtiment (CSTB), is the most highly valued. It ensures that renovated piping systems meet high standards of performance, durability, and safety. To obtain it, candidates must follow a strict procedure including theoretical assessments, practical exams, and sometimes a supervised work phase.

Tips for gaining practical experience

Gaining practical experience is crucial to excel as a pipe lining professional. It is important to take every opportunity to face real, diverse and complex situations, thus applying the techniques and materials studied in training. Working as a team and scrupulously respecting safety instructions and customer requirements are also essential.

Getting closer to experienced professionals can be beneficial to receive advice, tips and benefit from their feedback.

Keeping up to date with the latest innovations and techniques

The pipe lining industry is dynamic, benefiting from continuous technological innovations and product developments. To remain competitive, it is important to stay informed about the latest advances, new products and emerging practices. Continuous training is essential, whether through refresher, advanced training or specialization modules.

Participating in industry events, such as trade fairs, conferences or workshops, is also recommended to exchange with other professionals, discover innovative solutions and expand your professional network.

Conclusion

The pipe lining technique represents an advanced solution for the rehabilitation of sanitation systems. It stands out for its significant advantages, both from an economic and ecological point of view. This innovative method allows the restoration of pipes without requiring major works such as digging trenches or interrupting services, thanks to the insertion of a new layer of resin inside the damaged pipes.

To pursue a career in the field of pipe lining, adequate training, certification, rigorous preparation and continuous monitoring of innovations and technical developments are essential. This sector offers attractive and promising career prospects in the face of a growing demand for the renovation of rainwater and wastewater management networks.
