Micropiles are small cylindrical structural elements in lengths varying usually from 10 to 40 meters and in diameters ranging from 100 to 350 millimeters. These can be used in varied and diverse applications - as supports and structural foundations of roadway ramps, steel towers of transmission lines, industrial plants, tunnel roofs and old or existing structures that require preservation, strengthening, augmentation, or rehabilitation. As the plant and equipment do not demand big or wide working areas, micropiles can be constructed even in limited and narrow spaces.
