Soil mixing involves the mixing of cement or lime into the in-situ soil for ground reinforcement.
Why is it used?
Soil mixing uses a wide range of techniques to inject binder agents to mix with the soil and form columns, for example, to reinforce the ground for subsequent construction. The type and amount of binder will determine the hydraulic and mechanic characteristics of the soil.
How does it work?
Soil mixing generally comprises three stages: premixing of the soil, injection of the binding agent and incorporation of the soil/ binder mix.
Did you know?
The technique produces no, or very little, spoil. The structures produced by soil mixing can be columns, panels or continuous structures, such as trenches.
