Modular approach to the choice of waterproofing solution for the underground part of the building

Stable and long-term operation of buried foundations, tunnels and underground structures requires maximum protection against groundwater. Modern waterproofing methods are quite effective in protecting underground space from flooding and destruction of concrete structures. However, 95% of newly constructed facilities have problems associated with a violation of the waterproofing. The development and implementation of new technologies for waterproofing, digital monitoring and early warning systems for violations of the integrity of waterproofing systems is an urgent task of construction and production activities, it requires the development and improvement of relevant research methods. The purpose of the research in this article is to develop a methodology for choosing a rational option for waterproofing the underground part of the building. The main result of the study is the development of an algorithm for determining a rational and optimal option for waterproofing the underground part of a building based on a modular approach that allows you to justify and select the best technology for installing or repairing waterproofing of the underground part of buildings in operation, taking into account various conditions at the design stage. The developed methodology includes three modules of the system for choosing a design solution: determining the economic effect when comparing the costs of building an insulation system and subsequent repairs; classification of geological conditions of the construction site and accounting for operating conditions; determination of the terms of installation and terms of repair during the subsequent operation of the building. The proposed methodology can be considered as a concept for the development of approaches to quality assessment indicators.
