Waterproofing materials to protect the structures of transport structures

Abstract

The article is devoted to the problem of providing waterproofing and vapor barrier protection against the effects of water seepage or deicing salt solution. The question is raised that in the current conditions of modern construction, they do not always pay due attention to the issue of high-quality waterproofing coating, which in turn is one of the most important components for maintaining durability, for ensuring the strength and reliability of the main constructive structures of transport structures, and most importantly, for unconditional safety of people at these facilities. In the framework of this work, the types of waterproofing materials were analyzed and classified, the methods and conditions for the use of waterproofing materials were examined, and the positive and negative features of waterproofing transport structures were described. In addition, in this article, the authors examine in detail each of the types of waterproofing material separately, provide the positive and negative sides of each of them, and also describe the application technology. The experience of using sprayed, surfaced and coated waterproofing is also described. A positive example of the use of each type of waterproofing, and somewhere and the whole waterproofing system in the field of tunneling, both in Russia and in foreign countries, is considered. The experience of using the products of the most popular manufacturers of waterproofing materials on the Russian market in bridge building is also described, however, there are both positive examples and, unfortunately, negative ones in this area. Having analyzed the types of waterproofing systems and the experience of their application, we can conclude that in recent years special attention has been paid to the protection of structures, but effective and universal waterproofing for engineering structures has not yet been invented, in view of this, the area is promising for new discoveries.
