Abstract: A system and method of determining lift deflection during construction of aggregate columns allows for real time monitoring of construction to ensure meeting defined parameters. The amount of deflection of a tamper head during tamping is determined multiple times for each lift. When the amount of deflection matches a predetermined value, tamping is stopped.
