Jet Grouting for
Existing Culturally Important Library in Osaka

Objective	Renovation
Techniques	Jet Grouting
Period	01/2013～11/2014
Comment	Our jet grouting technique, JETCRETE was applied as a countermeasure against foundation ground liquefaction for the Osaka Prefectural Library, which was constructed during the Meiji era. JETCRETE was adopted because it has compact jetting equipment, combined with highly skilled jet grouting techniques and expertise, enabled construction in extremely narrow and confined spaces. As a result, the project was successfully completed without closing the library even during construction.
