Grounds of EGE-1 are non subsidence. Grounds group 29 В<br />
In case of underground waters peak level to height mark 41.0m the grounds get<br />
running properties. Accordingly, the grounds design resistance is accepted 80kPa.<br />
EGE-2 is presented by clay, loams, sand alternation. Grounds from humid to water<br />
saturated are non subsidence.<br />
Preliminary physical-mechanical properties of the grounds of EGE-2 are resulted in<br />
the below-mentioned table.<br />

Grounds group грунтов 8 B . Grounds are non subsidence. Grounds (according to<br />
archive data) are strongly aggressive to concrete on Portland cement, slag-Portland cement<br />
and sulfate-resistant cements.<br />
Underground waters are opened on 1.4m depths and more. Water is strongly<br />
mineralized and suitable for technical needs only. Underground waters are middle<br />
aggressive to concrete on Portland cement.<br />
Line of design communications are divided into two sites by passage: first site –<br />
<strong>Surgil</strong> CGTU– Urga CGTU– the territory of the former Aral Sea bed and the second site –<br />
Urga CGTU– Akchalak GCC – Ustyurt plateau.<br />
