Micropiles are deep foundation elements with a small diameter of up to 300 mm, through which loads from the superstructure are transferred into deeper, load-bearing soil layers by means of skin friction.

Micropiles are capable of resisting tensile, compressive and cyclic loads. Typical applications include the construction of new foundations as well as underpinning or strengthening of existing structures, such as buildings, bridges, retaining walls or masts, as well as the uplift resistance of structural elements in groundwater conditions.
