Advantages of Vibro Stone Columns

sc2web1. More economical than piling, percentage of saving per meter square (comparing stone column to piled embankment) can range from 20% to 70%, depending on the pile spacing, pile length and pile capacity.

2. Significantly simplifies substructure design and construction as compared to piling. Eliminate the needs of providing continuos pilecap / individual pilecap, cutting / lengthening of pile, reinforcement for pilecap etc. A layer of capping sand is already adequate for load transfer and achieve arching effect in the stone column.

3. Significantly reduces consolidation settlement of subsoil to 2 to 5 times lesser than without any treatment, or by prefabricated vertical drains.

4. Accelerate rate of consolidation. The rate of consolidation is very much shorter than prefabricated vertical drains. (In the range of about 6 months for PVD, can be reduced to about 2 months with stone columns)

6. No waiting period after installation as compared to PVD. Embankment construction can commence immediately after installation of stone column to full height of embankment.
