Improvements in the speed and automation of liners will allow contractors to take on larger, more time consuming projects. • Advanced Materials: Manufacturers are improving the properties of liners (i.e. elevated temperature/chemical resistances) to allow relining to be utilized in more stringent applications. • Diversification: Supply chain disruptions are easing and relied less on individual countries, allowing manufacturers to gain more control over pricing and project timelines. Due to the trends listed above, it is expected that the trenchless pipe relining market will continue to grow through 2027 and beyond. The level of competition in the marketplace will push the durability of trenchless relining systems, allowing customers to make purchases based on more than the lowest price. Newer, more efficient relining systems will allow customers to make purchases based on lifecycle costing. Recent Developments in the Trenchless Pipe Relining Market Trenchless pipe relining is expected to gain momentum through 2025-2027 as utility services companies shift from conventional pipe replacement methods to more planning and less disruptive methods. According to Lucintel, relining will be more predominantly in areas where the whole life cost of pipe replacement can be justified. • Rising Utility Capital Programs: The eighth (and latest) Asset Management Program (AMP) of England's water utility services companies (2025-2030) provides a capital program of about 100 billion pounds. This program is expected to increase companies’ focus on the rehabilitation of wastewater networks, thereby creating more opportunities for pipe relining. • Increasing Infrastructure Improvement Grants: The US Environmental Protection Agency’s May 2025 announcement of 6 billion dollars for the State Revolving Funds is expected to increase the pace of grants for water and wastewater improvement projects. Relining will be more prevalent to justify pipe rehabilitation over pipe replacement where other pipeline infrastructure (e.g. railroads, urban roadway tunnels, etc.) has to be reconstructed. • Large Contractor Reorganizations: Aegion's 2024 revenue of over 1.5 billion dollars indicated the need for large contractors in the rehabilitation service industry. Additional reorganizations and mergers are expected to occur to provide relining services to large utilities. • Digital Inspection, Remote Milling, and Resin Control: Currently, these technologies are used in niche, advanced maintenance activities. However, by 2025, there will be increased focus on reducing employee exposure to hazardous conditions during inspection and installation activities. This will particularly be the case for deep, high-demand, and/or chemically-aggressive wastewater infrastructure. As a result, a premium will be placed on the use of these technologies for such infrastructure. • Low-carbon Rehabilitation Procurement: The inclusion of carbon accounting in the infrastructure projects of utilities in the Sustainable Europe 2020-2027 framework will promote the use of trenchless technologies for the rehabilitation of water and wastewater infrastructure. Relining reduces the need for major infrastructure excavation and, therefore, reduces the carbon footprint associated with the transport of construction materials. During the same period, the companies involved will have to analyze and document the emissions associated with the relining process. Limitations in the availability of trained personnel and relining resins will continue to impact the trenchless relining market. During the next five years, the most successful companies in the trenchless relining market will be those who integrate inspection and assessment of wastewater infrastructure in the planning and design of renewal and replacement projects. Strategic Growth Opportunities in the Trenchless Pipe Relining Market The market for trenchless pipe relining is expected to grow as greater demands for less disruptive methods to replace and repair pipe infrastructure are made. Victoria University’s Trenchless Research Centre reports that water utilities are expected to move from emergency repair and replacement cycles to planned activities from 2024 to 2026. It is expected that demand will increase for pipelines relined with more durable, lower maintenance liners. • Sewer Pipe Relining: Sewer renewal (including replacement and rehabilitation) is being done in a way that reduces the need for road closures. The AMP8 program in the UK provides funding to support sewer renewal from 2015 to 2020, and other programs may be funded in the future. • Pipeline Relining: Other industries may benefit from the use of relining technologies. For example, various pipelines within a petrochemical complex may be relined to increase corrosion resistance and improve process pipeline integrity. • Sustainable Premium Materials: The Construction Products Regulation (CPR) of the European Union mandates that building products meet specified sustainability requirements. Consequently, the demand for construction materials with substantiated sustainability data will increase. Simultaneously, the focus on service life and embodied carbon of construction materials will encourage the use of procurement processes to meet specific customer requirements. As a result, there will be a shift toward the use of certified materials. • Digital Design and Inspection: Advances in the use of artificial intelligence (AI) will allow the selection of the optimal liner during the rehabilitation of underground pipelines. Adequate data and computer models will facilitate the assessment of the hydraulic performance of the rehabilitated pipelines. The 2025 US Infrastructure Act will result in a greater demand for the rehabilitation of water conveyance systems. Data shows that approximately 40% of the water mains in the US are more than 50 years old. Reliable data will facilitate the assessment of the condition of pipelines, and assist in determining when rehabilitation and/or replacement of pipelines is required. • After Market Services: The US Infrastructure Investment and Jobs Act of 2021 provides funding to State and Local governments to improve water systems. Service focused companies will build long-term customer relationships. Companies will make additional revenues from after market services. Winning companies will be engineering-focused and provide after market services. The largest customer base for rehabilitated pipelines will be municipalities.

Trenchless Pipe Relining Market Drivers and Challenges Trends in the trenchless pipe relining market are impacted by the need to replace and rehabilitate water and wastewater pipelines. Other impacting factors include increased focus on sustainability and availability of alternative technologies and methods. Cost savings associated with lowered excavation and restoration are driving the preferences of water utilities. Challenging economic conditions, limited availability of skilled labor and increased material costs impact the market negatively. Long term outlook and continued development of urban areas ensure reliance on trenchless technology. Relining of water and wastewater pipelines has the potential to serve a variety of markets including municipal, industrial and commercial. The factors responsible for driving this market include: • Urbanization and Client Requests: The intense building development in cities has meant a surge in the need for repair and maintenance of existing infrastructure. By 2050, 68% of the world’s population is expected to live in cities, according to the UN. As the demand for municipal and utility services increase, so does the need for quicker, less invasive methods to repair and maintain infrastructure. New methods like pipe relining cause less disruption to the public and take less time to complete compared to conventional infrastructure repairs and maintenance. • Improving Technology: Reliable, high-speed communications networks and the increasing availability of computing resources have permitted the use of increasingly large data sets, advanced analytics, and visualization in designing and assessing pipe rehabilitation. In 2025, industry specialists believed that reliance on manual assessment for quality assurance was declining. In the next 3 to 5 years, even greater reliance on automation, data science, and artificial intelligence will transform pipe relining by expanding the range of pipe shapes, sizes, and types. • Sustainability and Lower Disruption: Relining helps reduce disruption, soil removal and use of heavy equipment when compared to traditional pipe replacement. The consideration of carbon and circular economy aspects, in addition to cost and function, in the awards of public contracts starting from 2025 implies that, from an award critique perspective, trenchless rehabilitation has multiple competitive advantages, especially in urban environments. Less excavation, construction waste and disruption aid in the achievement of environmental goals and objectives, and help in the alignment with the commitment to reduce CO2. In the next 3-5 years, the situation will be similar when considering climate change and the environment, as well as the resistance of the citizens to the increase of the amount of construction works. • Price and Manufacturing: In 2025, the manufactures of relining materials and equipment have improved technologies and equipment to reduce the time and cost of relining. Volatility of raw material prices positively impacts the liner industry and investment into production systems, processes and project management. In the next 3-5 years, greater emphasis will be placed on the total cost of ownership (TCO) by the utilities, and reductions in the service life of infrastructure and the subsequent maintenance burdens will be the critical factors in the purchase of capital equipment. The challenges facing this market include. • High Costs and Financing: The use of specialized liners and resins, along with the required inspection equipment and services of engineering crews, increases the up-front cost of relining. In 2025, infrastructure programs faced multiple initiatives, including transportation, energy, and flood control. As a result, lower-priority programs, such as wastewater, may not have been funded. Furthermore, smaller wastewater utilities may defer relining and select less-expensive, short-term patching. Relining offers long-term savings and reduced disruption; however, in the next three to five years, constrained municipal budgets, together with increased costs of capital, may create an implementation gap. • Site Constraints: Relining depends on the condition of the pipe, groundwater, and other site constraints beyond the control of the relining contractor. In 2025, relining remained the preferred alternative to rehabilitate pipes; however, the presence of severe pipe deformations, pipe collapses, and/or anchorage constraints often required the use of invasive or no-dig techniques. Relining, and the inspection and assessment thereof, requires the integration of several specialized and inter-dependent trades, including engineering. The lack of quality assurance may result in relining failures. • Complexities in Regulation, Workforce, and Supply: There are many building codes, approvals, and requirements related to the safety and the protection of the environment and workers that vary by jurisdiction. Contractors have faced challenges due to the unavailability of skilled engineers, inspectors, and technicians. Chemical and equipment supply chains became unpredictable due to energy and other changes in the cost of transportation. This situation affected the cost and the time required for completion of projects. In the coming years, the focus should be on training and placement of the workforce, local manufacturing and sourcing, along with improved project and procurement management to achieve even and consistent growth in the market. A number of factors like the need for more space in urban areas, unsustainable methods of transport, and the need for more sustainable methods of transport create a demand for trenchless technology. This creates an opportunity for the pipe relining industry. Furthermore, the constant improvement in the technology and materials used in relining increases the performance and decreases the time required for curing. While the technology and relining methods are improving, various regulations and workforce capabilities remain fragmented. Therefore, companies that integrate technology, relining and repair services, and consulting are best positioned to succeed.
