Top-down method is a rapid method which enables builders to construct the substructure and superstructure simultaneously. Likewise it is used as an excavation stabilization method in cases where you can’t or you are not allowed to use the other geotechnical methods such as soil nailing and soil anchorage.

Sheet pile walls are usually installed to support temporarily or permanently the excavations in unstable soils. In large depth the sheet piles are usually supported from lateral movements by anchorage or reciprocal supports.

Different types of barriers are used to avoid mortal results of falling large and small rock or debris. Determining the determination of the potential falling rock weights and the calculation of the impact energy is the key point to decide the type of the barrier.

Deep soil mixing (DSM) is a method in which the soil is mechanically mixed with adhesive binders to increase the strength and bearing capacity of under laying soil to the desired depth. Depending on the soil and water table situation the wet or dry methods are applicable.
