Beck web site, viewed April 18, 2019 (Compaction and Jet Grouting: Grouting is a ground improvement technique utilizing a relatively stiff (low mobility) grout injected at high pressure into a relatively loose granular stratum for densification; typically used to increase bearing pressure and reduce settlement of proposed structures; can be used to re-level structures that have settled, and to densify beneath structures proposed for increased loading. Compaction grouting: bulbs of highly viscous grout are injected in the ground from the base up at a slow injection rate. Jet grouting is a similar bottom up grouting technique, but utilizing very high pressure (4,000 to 6,000 psi) grout injected through small nozzles at very high velocity) Hayward Baker web site, viewed April 18, 2019 (Low mobility (compaction) grouting is the injection of a low slump, mortar grout to densify and reinforce soil or fill subsurface voids) |
