2017-4-19 Sand compaction piles (SCP) of soil improvement techniques act as drains and under favorable conditions can significantly decrease the time for primary consolidation to occur. Furthermore, the construction of sand piles reduces the build-up in pore pressure in granular layers, and hence decreases the soil potential to liquefy during an earthquake. Sand is often readily available near most construction sites, and it‟s considerably less expensive than other processed materials such as crushed stone which may have to be imported from a considerable distance by a considerable cost. Either bottom feed stone column equipment or sand compaction pile equipment can be used to construct sand piles.
