ABSTRACT:
A method of grouting fine-grained soil mediums is presented that uses an injection process operating at low constant pressure. The process provides for deep penetration of fine sands by injecting a dilute suspension grout composition comprising water and cementatious particles. The grout composition is characterized by a water to cementatious particles ratio of at least 4:1 by weight.
