Top-Down Construction Method

Top-Down Construction MethodTop-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.

Soil Nailing

Soil Nailing

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.

Deep Soil Mixing

Deep Soil Mixing

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.

Soil Improvement

Soil Improvement

Soil improvement is a pack of solutions to help the soil to tolerate the applied loads and conditions in a safe and determined manner. Solutions like compaction and RIC and stone columns, soil replacement, drainage, grouting, soil mixing and so on, are mainly used in this regard.
