What depth and capacity can a micropile achieve? Micropiles can penetrate in excess of 50 meters in depth, with design loads of as much as 500 tonnes however production micropiles typically have a capacity of between 30 (30kn) and 150 tonnes (1500kn) per pile. A significant advantage of micropiles comes from their ability to be grouped.
