JET GROUTING

Jet grouting is a method for forming foundation elements in soils and, in some cases, semi-rocks. The technology consists of mixing the existing soil with a cement mixture under high pressure of about 40–45 MPa. Along the grouting well, a column of grouting-consolidated soil is formed by rotating jets as the grouting monitor is smoothly removed. Soil is compressed in the vicinity of the JG column and therefore consolidated.
