The development of underground space in the design of buildings and complexes determines the direction of modern construction. Special attention is paid to the use of new technologies and the organization of production in the development of underground spaces of historically developed urban areas. Constrained conditions of construction in existing urban development represent construction site bounded by city buildings and structures with their subterranean communications with the adjacent road network and land facilities. In such a situation when doing work to minimize the effect of underground construction on the existing development and the geological environment is required when strict compliance with the building regulations. The method "wall in the ground" can be considered important and priority in the technical progress of construction of buried structures.

Modern urban development policy pays special attention to the application of new and well-known technologies in the development of underground spaces of historically developed urban areas. Rational use of urban areas occurs up and down, without expanding the boundaries of urban areas. Technology "slurry wall" in the development of underground space continues to rapidly gain popularity. The use of this method allows to solve the problem of construction in cramped conditions and is one of the most popular in modern urban development practice
