During the deep excavation for the opening foundation pit some problems might occur such as horizontal movement, settlement which are eliminated safely by our company. Mainly foundation pits are opened at safe-stable slopes and open excavations or excavation of supported internal wall by opening vertical- near vertical slopes. 

In order to select economic and safe drilling system design parameters such as soil type and strength, location of adjacent structures, groundwater conditions, the period during  which the foundation pit will remain open, cutting slope preservation, edge and base stability, horizontal and vertical displacements that may occur n the region are investigated. A detailed examination is performed.

The retaining system according to surrounding structures’ condition and the characteristics of the ground layer are selected during deep excavation. This retaining can be concrete, timber or steel curtains of sheet piling, diaphragm walls, cast-in-situ piles, concrete and soil nailed walls. The horizontal retaining and anchorages may be required for stabilization for this kind of restraining after crossing a certain depth.
