1.1 ST This Standard is applicable to the execution, testing and monitoring of jet-grouting works. Some considerations about design are also given. 1.2 ST The execution of jet-grouting works requires knowledge and experience in this type of contruction. NOTE 1: The jet-grouting process must be distinguished from the grouting processes covered by the standard EN 00288006.
