Purpose: to analyze the condition of irrigation canals and technologies for repairing lined irrigation canals with composite materials to increase their durability and reliability.
Materials and methods. The method of empirical cognition, which served as a synthesis for the theoretical analysis of literature by the deductive method, which included abstracting, taking notes and quoting of general and special scientific works of scientists are used. The mathematical and statistical methods were also used.
Results. The traditional methods of the irrigation canal lining face a number of problems that can affect their efficiency and longevity. Compared with them, the composite materials have a number of advantages in the irrigation canal repair, due to which they are considered a valuable innovation in this field: strength and durability, corrosion resistance, low weight (mass), chemical resistance, heat resistance, low maintenance costs, ease of installation, resistance to biological influence. Thus, the use of composites in the irrigation canal repair allows not only to increase their strength characteristics, but also to reduce the overall cost of operation that makes them one of the preferred options in modern construction and infrastructure repairs. There are several advanced technologies and repair methods using composite materials that are used in the restoration and reinforcement of irrigation channels: on-site lamination, composite material spraying, hand-spreading, robotic spreading systems, fiber membrane, resin injection systems, 3D composite printing, geosynthetic materials.
Conclusions. The use of innovative impervious materials reduce water losses in irrigation systems, increasing their reliability and performance, which ensures the irrigation structural stability for a long time.
