The construction area belongs to the IVG construction and climatic subdivision and is characterized by the following natural and climatic indicators:

- design ambient air temperature - min. 25 ° С;

- site seismicity - 5 points;

- standard value of snow load - 0.50 Kpa;

- standard value of wind pressure - 0.38 Kpa;

- normative depth of ground freezing - 122 cm;

Geomorphologically, the construction area is confined to the surface of the right-bank terrace of the river. The Ural is a low-wavy plain with a common slope towards the Caspian Sea.

According to the report on engineering and survey works No. 33II000 of the Caspian Institute of Exploratory Geophysics LLP in 2013, the assigned site for the construction of the base is composed of bulk trapped loamy soil with a layer capacity of 0.9 1.0 m - EGE 1. The underlying layer is EGE 2 - water-saturated sandy sandy, ductile with a layer thickness of 9.0-9.1 m.

As the foundation of the foundations of the modular building, EGE 2 is adopted, having the following physical and mechanical characteristics :

- humidity at the flow boundary - 0.2

- humidity at the rolling boundary - 0.17

- ductility number - 0.03

- natural humidity -0.19

- yield index - 0.93

- humidity degree - 0.9

- porosity coefficient - 0.59

- dry soil density - 1.69 g/cm3

- deformation modulus - 18.0 mpa

- design value of soil density PII/I 2.01/2.05/cm3

- - II - specific adhesion C II/I 8.0/6.0 Kpa

- - II - the angle of internal friction 21o/16 about

Sandstones are not sedimentary and not swellable, but according to the characteristics given, they are weakly to medium-dwelling.

Groundwater at the site lies at a depth of 1.2 1.3 cm from the natural surface

Soils are higher than UHF on concrete and iron-concrete structures at the grade of concrete in terms of waterproofness W6 in terms of chloride content, the degree of aggressive impact is medium, in terms of sulphate content for grade concrete.

W6 to sulphato resistant cements (GOST 2266895) - weakly aggressive.
