  • Design and Quality

    The compaction of the in-situ soil is the most important positive effect of vibrocompaction or stone columns for the prevention of liquefaction in granular soil layers. In soils with a silt content of over 10 % the most important effect of the stone column is the reduction of the total cyclic shear stress in the soil.
