It is shown that well designed ground improvement schemes may effectively replace conventional foundation solutions for a wide range of applications involving heavy loads and structures sensitive to settlement. This is achieved without compromising stringent design criteria. The presented case studies illustrate the use of four ground improvement methods: deep vibro-compaction, vibro-replacement (stone columns), wet deep soil mixing and jet grouting. These methods were used in different projects and soil conditions, alone or in combinations. Beneficial returns in terms of construction costs, shortening construction time and reducing CO2 emission are discussed where applicable.
