Abstract
A machine, method and system for installing helical foundation piers that sues a driving tamper connected to a rotary tool to drive helical piers into the ground. Once the pier reaches the target depth, the tamper is decoupled, and counter rotated away from the pier. While it is withdrawn the soil between the driven and pier and the driving tamper is compressed by intermittent downward action of the tamper.
