Grouted micropiles are a drilled, 2-part deep foundation system (up to 200 feet) with 5-12 inch shafts. Grouted micropiles are made up of steel casing, rebar, and grout. They are suitable for areas where ground conditions are less than ideal, including limited access, obstructions (natural or man-made), and problematic soil. Micropiles can be used on a variety of projects, including the fortification or creation of foundations for bridges, towers, and new buildings. Their versatility has led to their increased popularity and use in complicated construction conditions.
