Mass Stabilization as a Ground Improvement Method

2018-9-19  Deep stabilization (deep mixing) methodologies encompass a number of methods applied to stabilize peat masses in situ. Of these, the mass stabilization method is one of the commonly applied methods. Mass stabilization is taken to mean a ground improvement method in which added binder is mechanically mixed into the soil mass to harden and improve its engineering characteristics.

About Deep Soil Mixing - Soil Stabilisation, ground ...

THE DEEP SOIL MIXING TECHNIQUE. Deep soil mixing is an in situ ground improvement technique that enhances the characteristics of weak soils by mechanically mixing them with a cementitious binder. The action of mixing materials such as cement, fly ash, lime or bentonite with soil causes the properties of the soil to become more like soft rock.
