Ground improvement, or ground modification, is defined as the alteration of site foundation soils or project earth structures to provide better performance under design and/or operational loading conditions (Schaefer et al., 2012).

What is meant by ground modification?

Ground modification is a process that involves improving the ground — not merely treatment. It involves the alteration of site foundation conditions or of earth structures in order to enable better performance under design and/or operational loading conditions.

What are the different methods of modification of soil?

Currently, there are several techniques of soil modification, most notably compaction and stabilisation. Stabilisation is usually achieved by the addition of binders (lime, cement). A lesser known technology of soil modification is fluidification by means of fluidifiers, plasticisers, or other admixtures.
