Jet Grouting

Jet grouting was performed in the narrow space as foundation settlement countermesure of historical residence, which is designated as an important cultural property.

For jet grouting, JETCRETE, which is our jet grouting method that has an ability to construct jet grouting columns using small jetting machine, was used to perform jet grouting in the narrow area inside the building.
