Biocalcification
A process that uses bacterial activity to precipitate calcium carbonate in the form of calcite onto soil grains, creating a new, more resistant cohesive material.
Injection
Under pressure, grouting introduces a more or less viscous grout into soil voids to reduce permeability and/or increase mechanical properties. A distinction is made between impregnation grouting and slurry grouting. Grouts can be based on hydraulic binders, chemicals or resins.
Deep Mixing Method
Mixing the soil in place with a hydraulic binder to form a new "soil mix" material.
Jet grouting
A technique involving the creation of "soil concrete" columns by injecting cement grout under very high pressure, which destructures the soil...
