Micropiles are deep foundation elements with a small diameter of up to 300 mm, by means of which loads from the superstructure are transferred to lower-lying, load-bearing soil layers through skin friction.
Micropiles can transfer tensile, compression and alternating loads. Typical applications are the foundation or strengthening of existing foundations of structures (e.g. buildings, bridges, retaining walls, masts etc.) or uplift restraint for structures in groundwater.
