- Increase bearing capacity
- Decrease settlement
- Liquefaction Mitigation
The pier location is initially pre-drilled for soils where the hole will remain open. In soils that cave or collapse, a bottom feed vibrator can be used. The down-hole vibrator is lowered vertically to the planned tip of the pier by a standard crane or rig built for this technique. Aggregate (new crushed stone or recycled concrete) is then added to the hole or through the bottom-feed system and is compacted in lifts by repeated penetrations with the vibrator. The vibratory energy densifies the aggregate and any surrounding granular soil. The high modulus pier reinforces the treatment zone.
