Compaction grouting was used for the soil stabilization phase of settlement repairs to the West Orange County, California courthouse. The 8 yr old concrete and masonry structure was founded on a pile foundation 25 ft to 40 ft (7.63 m to 12.20 m) deep with differential settlement. Compaction grouting was selected as the best solution as it affords close control of the zone of grout deposition due to the stiff, mortar-like grout and special injection procedures used. Therein grout remains in a homogeneous mass, compacting the soil as it expands due to injection pressure. A total of 32,729.36 cu ft (916.5 cu m) of grout was injected into 162 holes. Work proceeded from the top down utilizing 1,185 hole stages of about 6 ft (1.83 m) each. Following stabilization, the structure was restored to its proper grade and necessary structural and cosmetic repairs made. /ASCE/
