Ground improvement is the primary application of many geotechnical construction techniques, permitting construction on soils by changing their charactertics. Soil mixing increases shear strength and reduce compressibility and permeability of soft soils.

Methods:

  1. Surface Compaction.

  2. Drainage/Surcharge.

  3. Electro-Osmosis.

  4. Grouting.

  5. Blasting.

  6. Dynamic Compaction.

  7. Stone Column.

  8. Sand Drain.
