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.
Shotcrete is a process of spraying concrete to the soil faced walls to create a concrete facing for reducing erosion and weathering of soil and rock. Also it is a structural part in soil stabilizing methods and tunneling as well. It could be reinforced by steel or PP fibers and steel wire mesh.
Soil nailing is a passive method for stabilizing deep excavations and steeply lands. This method can provide enough safety factors against any possible rupture limits during and after excavation and also limits the ground movements and sometimes is applied for strengthening existing unstable ground.
