Use Columns Settlement For Free

Stone column ground improvement involves adding vertical columns of stone into the ground to a depth of at least 4m below the ground surface. A layer of compacted gravel can then be put over the top of the columns, ready for the construction of new house foundations.

Like most ground improvement techniques, stone columns are used to reduce settlement and increase load-bearing capacity. They also accelerate soil consolidation as a result of the drainage capacity of the granular material within the columns, which act as pore or water pressure evacuation points.

A stone columns technique is one of the soil stabilization methods that is used to increase strength, decrease the compressibility of soft and loose fine graded soils, accelerate a consolidation effect, and reduce the liquefaction potential of soils.

The pile can be fully or partially driven into the soil, or part of it submerged into water, it supports the superstructure and it has no man-made element uder it, only above, while the column is resting on the foundation, which is a man-made element.

Stone columns help to limit the amount and consequences of future liquefaction by: Densifying the soil through vibration and introducing stone into the soil ? Reinforcing the soil creating a stiff composite soil mass.

It is believed that the proper installation of stone columns by vibro-replacement mitigates the potential for liquefaction by increasing the density of the surrounding soil, providing drainage for the control of pore water pressures, and introducing a stiff element (stone column) which can potentially carry higher ...
