Understanding pipeline lining: Fundamentals and benefits

What is pipeline lining?

Pipeline lining is an innovative method to renovate sanitation networks without replacing damaged conduits. This technique involves inserting a new resinous layer inside the pipelines, offering a solution that is both economical and ecological. It extends the lifespan of pipelines while optimizing their functionality.

Advantages of lining for pipeline rehabilitation

Adopting lining as a repair solution avoids destruction, the need to dig trenches, and allows maintaining activity without interruption. This method effectively addresses 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 pipeline lining, depending on the network's specifics and the client's needs. The most commonly used methods include:

• Lining by resin spraying: This modern technique involves spraying epoxy or polyester resin onto the internal walls via a robot. It is fast, flexible, and suitable for diameters from 40 to 600 mm.
• Lining by sleeving: 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 getting started

Assessing the required skills and knowledge

Pipeline 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 necessary 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 appropriate equipment and quality materials is essential. It is important to choose equipment suited to the dimensions and configuration of the pipes to be renovated. Selecting resistant, durable materials that ensure good adhesion and watertightness is also crucial.

Different types of resins and liners are available on the market, each with specific characteristics and performance. It is therefore advisable to inquire about each option and seek professional advice to make the best choice.

Understanding current regulations

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

To guard against potential fines and ensure a service that meets expectations, it is essential to stay informed about current regulations and keep up to date with legislative and normative changes.

Establishing a solid business plan

Pipeline lining offers significant market opportunities, driven by increased demand for sewer network renovation. This method, less costly and more practical than full pipe replacement, attracts a growing number of clients.

It is therefore crucial to develop a robust business plan, clearly defining objectives, resources, and development strategies. Market analysis, competition, customer needs, financing options, and communication strategy are necessary for success.

Training and hands-on practice to become a professional

Training options available for pipeline lining

Pipeline lining training offers several pathways, adapted to the initial level and objectives of each candidate. Options include initial training provided by specialized institutions such as the National Water Trades Training Center (CNFME) or the Institute for Training and Research on Health and Social Organizations (IFROSS). For those seeking continuing education, private or public organizations like Docteur Canalisation or Curatec offer targeted modules on various lining techniques and materials.

Learning can be enhanced through practical internships conducted on real sites or within platforms dedicated to pedagogy.

Obtaining the necessary certification

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

In France, the NF390 certification, granted by the Scientific and Technical Center for Building (CSTB), is the most valued. It ensures that renovated pipe systems meet high standards of performance, durability, and safety. To obtain it, candidates must follow a strict procedure including theoretical evaluations, 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 seize every opportunity to face real, diverse, and complex situations, thus applying the techniques and materials studied during training. Working as a team and strictly adhering to safety instructions and client requirements are also essential.

Connecting with experienced professionals can be beneficial for receiving advice, tips, and benefiting from their feedback.

Stay up to date with the latest innovations and techniques

The pipe lining sector 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. Continuing education is essential, whether through refresher, advanced, or specialized modules.

Participating in industry events, such as trade shows, conferences, or workshops, is also recommended to network 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 economically and ecologically. This innovative method allows the restoration of pipes without requiring heavy work such as trenching or service interruptions, thanks to the insertion of a new resin layer 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 response to a growing demand for the renovation of stormwater and wastewater management networks.
