Advantages |
Able to reduce the work duration & construction cost by large diameter. |
Able to produce uniform improved substance through composite relative mixing. |
Able to apply to hard ground because of its heavy duty mixing equipment. |
Disadvantages |
Construction cost is high as compared to compaction method. |
Unable to perform installation work close to structures due to mechanical stirrer. |
Need to dispose the upheaval soil as construction work in progress. |
Applicable Ground |
Mostly all types of soil such as sandy soil, cohesive soil, and organic soil etc. |
Objectives |
Structural Foundation, Prevent Slip Circle, Prevent Settlement, Prevent Liquefaction |
