Micropiles are specifically effective where natural or person-built obstructions arise, in constrained access or small-headroom disorders and in karst geology exactly where rock surfaces are erratic and enormous voids are usually existing. They will typically be designed to resist compression, uplift and lateral loads and happen to be used to support several different services. Installation techniques may be tailor-made to be certain minimal harm to existing foundations and to allow facility operations to become preserved throughout construction.
