COMPACTION GROUTING CONSENSUS GUIDE COMPACTION GROUTING CONSENSUS GUIDE Committee of the Geo-Institute of the ASCE Copyright of the COMPACTION GROUTING GUIDE Committee of the Geo-Institute of the ASCE 20077 August 2007 DRAFT ABSTRACT COMPACTION GROUTING is a viable technique for densifying loose fills and native soils that permit adequate fluid pressure dissipation. The process involves injecting a stiff mortar-like grout into the ground to displace and compact the surrounding soil. During injection, the grout displaces the soil and forces the soil grains into tighter packing, expelling air and/or water out of the effected area, and reducing pore volume. At the end of injection the ground should contain stiff grout masses and densified soil.
This document is intended as a practical guide for those interested in specifying, designing, and/or undertaking compaction grouting. Field aspects of compaction grouting are discussed, including compaction grouting equipment, grout mix design, site investigation, and verification. The analysis and design sections of the Guide encompass
