Techniques
Compaction grouting
Compaction grouting is a process used for improving the engineering characteristics of a soil, through the high-pressure injection of stiff mortar through cased boreholes.
The grouting is usually carried out bottom-up, in successive stages of about 1 m. As the mortar is pumped in, it displaces and densifies the surrounding soil. The degree of compaction depends on soil characteristics and on the chosen grid pattern.
