What is a micropile?

A micropile is a small diameter drilled and grouted pile used to reinforce a foundation. In many instances micropiles are used in this area to gain friction for the stabilization of a foundation when bedrock cannot be reached. The project will use micropiles for the new bridge because a pile machine is quite large. If there were used, they City would not be able to construct the new bridge in place while keeping the existing bridge open. This also makes the construction footprint much smaller with less impacts. Recently the City used these on the Midland Avenue Pedestrian Bridge and the 14th Street Pedestrian Bridge.
