Bibliography

Applies 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 is a process in which 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).
