适用范围：This standard is applicable to the execution, testing and monitoring of geotechnical grouting work. Specific aspects concerning design are provided since ENV 1997-4 has been abandoned. Grouting for geotechnical purposes (geotechnical grouting) is a process in which the remote placement of a pumpable material in the ground is indirectly controlled by adjusting its rheological characteristics and by the manipulation of the placement parameters (pressure, volume and the flow rate). The following principles and methods of geotechnical grouting are covered by this standard: — displacement grouting (compaction grouting, hydraulic fracturing); — grouting without displacement of the host material (permeation, fissure grouting, bulk filling). Specialized grouting activities, generally associated with structural and/or emergency works, are not covered by this standard.
