Improving Soil Quality

Improving Soil Quality

1. Increase the bearing capacity of the soil by improving the shear strength of the soil

2. Reduce shrinkage and swelling of soils.Soil shrinkage is generally confined to the upper portions of a soil. Shrinkage and shrinkage cracks are caused by a reduction in soil moisture content through:

   • Evaporation from the soil surface in dry climates
   • Lowering of the groundwater table
   • Desiccation of soil by trees during temporary dry spells in otherwise humid climates

3. Reduce the liquefaction potential. To reduce liquefaction potential, we can use vibro-compactor or lower the GWT.

4. Increase the safety factor against possible slope failure of embankments and earth dams

5. Reduce the volume of material moved off site
