GM22S is a drilling rig designed for column stabilization. It is excellently suited for all applications where soft ground must be strengthened with column stabilization to make it suitable for construction. The GM22S is a functional tool for e.g. infrastructure builders and for the needs of the mining, earthworks and construction industries.
In column stabilization, a hole of about 20 meters deep is pressed in soil. Lime or cement-based binder is fed into the hole and mixed with the soil at the same time. The binder solidifies into the soil as a column when it reacts to soil moisture.
