Rigid inclusions are an economically advantageous form of land improvement. There are unreinforced concrete columns, installed to take vertical loads.
In soft clays, rigid inclusions can be installed by dislocating the ground with a bottom closed vibrated metal tube.
This allows the soil to be improved by applying lateral forces, compacting it. Then the metal tube is filled with concrete.
The tube is extracted by vibration, vibrating the concrete, ensuring the quality of the inclusion.
In some cases, where vibrations are not an option:
➜ They are drilled with vertical drilling equipment.
Our teams can install rigid inclusions by vibration, using the Silent Piling method or using a drilling rig.
