Grouting

Grouting involves 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.

Permeation grouting

Permeation grouting can be used to construct deep sealing blankets in sand or gravel. Grout pipes with valves are inserted in a grid spacing into the ground, using vibration or installed in drill holes through which the grout is then injected. Grout bodies are created around the valves, forming a continuous sealing blanket. 

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.
