Micropiles were conceived in Italy within the early 1950s, in reaction towards the demand for ground breaking methods for underpinning historic structures and monuments that had sustained injury with time, and especially all through Earth War II. A reputable underpinning program was needed to assist structural masses with minimum motion, and for installation in access-restrictive environments with negligible disturbance to the present construction.
