VSL | Ground improvement

Ground improvement is about changing the properties of the soil with various techniques depending on the ultimate objectives. Compaction. Compaction consists in rearranging the soil particles in order to reduce the voids and increase the density. This translate into a ground that has better mechanical properties and that can bear higher loadings.
