They could typically be designed to resist compression, uplift and lateral loads and have been utilized to assistance a number of services. Installation techniques is usually tailored to be certain minimal damage to existing foundations and to permit facility functions to be maintained for the duration of construction. Micropiles tend to be used to assistance very large capacities with little if any motion from the foundation.
