Reliable waterproofing protection is one of the conditions for ensuring the durability of transport and hydraulic structures. However, among the dominant causes of the destruction of transport and hydraulic structures is the premature destruction of waterproofing, which is one of the least durable elements of the span structure.
A waterproofing system used to protect concrete and metal structures of transport and hydraulic construction must have reliability, which is represented by the performance of the necessary functions under operating conditions for a given time while maintaining the main characteristics, and have a service life as close as possible to the structures being insulated.
Waterproofing materials have two interrelated characteristics: internal structure and quality indicators. The relationship is established with optimal structures, when stable bonds in them ensure the stability of the main properties during various external and internal changes in the material in the structures. The internal structure, or structure, of waterproofing materials expresses a certain nature of the bonds and the order of adhesion of the particles from which they are formed.
The most advanced in terms of ensuring the protection of the slab are liquid composite membranes based on polyurethane and methyl methacrylate resins. Membrane coatings form a continuous seamless structure on surfaces of complex shape, since their application is carried out by the method of liquid spraying.
Research into the influence of various factors on the durability of waterproofing membranes based on methyl methacrylate is a crucial component for developing a technology for installing waterproofing membranes based on methyl methacrylate resin on transport and hydraulic structures and establishing requirements for them.
Problems. It has been established that there is a need to generalize existing approaches to protecting concrete and metal structures in transport and hydraulic engineering construction and to develop recommendations for the installation of waterproofing systems based on methyl methacrylate resin.
Objectives. The purpose of the scientific work is to conduct research aimed at generalizing the protection of concrete and metal structures of transport and hydraulic engineering using methyl methacrylates, which are arranged in the form of waterproofing of structures.
Results. Based on the conducted research, existing approaches to the use of waterproofing systems based on methyl methacrylate resin on transport and hydraulic structures were summarized and recommendations were developed for the installation of waterproofing systems based on methyl methacrylate resin.
Conclusions. The paper provides recommendations for preparing the surface of transport and hydraulic structures for installing a waterproofing system, which complement the current regulatory documents of Ukraine, the main technological operations and features of installing a waterproofing system.
