The use of clayey soils in the construction of subgrade allows to reduce the use of sandy soils, thereby reducing the number of quarries formed. However, this requires the implementation of constructive measures aimed at ensuring reliability, strength and safety. One of the ways to implement such activities is the use of geosynthetic materials. In the article, based on the experience of designing and building objects with geosynthetic materials, the criteria for choosing their types depending on the tasks being solved are established. The necessity of developing a mathematical model substantiating the decisions taken is considered. The obligatory organization and conduct of geotechnical control is noted as a tool to determine the directions for the development of this area of ​​construction in order to reduce the technogenic load on the territories associated with the withdrawal of natural resources.
