DIN EN 12715:2000-10

The document is applicable to the execution, testing and monitoring of geotechnical grouting work. Specific aspects concerning design are provided since ENV 1997-4 is not yet available. Grouting for geotechnical porpuses (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 parameter (pressure, volumen and the flow rate). The following principles and methods of geotechnical grouting are covered by the document: displacement grouting (compaction grouting, hydraulic fracturing); grouting without displacement of the host material (permeation, fissure grouting, bulk filling).
