This document is applicable to the execution, testing and monitoring of geotechnical grouting work.<\/p>\n

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).<\/p>\n

The following principles and methods of geotechnical grouting are covered by this document:<\/p>\n

    \n
  1. \n

    displacement grouting (compaction and compensation grouting);<\/p>\n<\/li>\n

  2. \n

    grouting without displacement of the host material (permeation, fissure\/contact grouting, bulk filling).<\/p>\n<\/li>\n<\/ol>\n

    Figure 1<\/span> illustrates the various injection methods associated with these two principles.<\/p>\n

    The principal objectives of geotechnical grouting are:<\/p>\n

      \n
    1. \n

      the modification of the hydraulic\/hydrogeological characteristics of the ground;<\/p>\n<\/li>\n

    2. \n

      the modification of the mechanical properties of the ground;<\/p>\n<\/li>\n

    3. \n

      the filling of natural cavities, mine workings, voids adjacent to structures;<\/p>\n<\/li>\n

    4. \n

      inducing displacement to compensate for ground loss or to stabilize and lift footings, slabs and pavements.<\/p>\n<\/li>\n<\/ol>\n

      Specialized grouting activities, generally associated with structural and\/or emergency works, are not covered by this document.<\/p>\n

      The execution, testing and monitoring of jet grouting work is not covered by this document and is covered by EN 12716<\/span><\/span>.<\/p>\n
