Grouting

Grouting involve introducing hard-setting slurries and solutions into fractures, cavities and gaps in soil or rock. A distinction is made between injections with and without modification of the construction soil. The choice of grouting agent depends on the purpose of the activity and the geological characteristics of the construction soil. Thanks to our know-how and our worldwide experience in a wide range of grouting methods, we are just the ideal partner for your project.

Jet grouting / High pressure injection (HDI)

Jet grouting is used for strengthening or deepening building foundations, for sealing bases or strut bases and for dam sealing. After reaching the target depth, a part of the soil is flushed out using fluid. The binder slurry introduced at the same time hardens the remaining soil. 

 

Rock grouting

Rock grouting is carried out in order to fill gaps, fractures and cavities in solid rock. In stable rock, injection follows the upstage sequence (from bottom to top), while the downstage sequence (from top to bottom) or multiple packer sleeved pipe (special design) is used in unstable rock.
