Micropiles & Minipiles

Micropiles or Minipiles are small diameter piles comprised of a central steel component with an annular surround of grout that is in contact with the soil, often employed where access for large piling equipment is prohibited.

Micropiles are high-performance, high-capacity drilled deep foundation elements typically between 5–12 inches in diameter that can extend to depths of 200 feet and achieve working loads of over 200 tons. Micropiles are comprised of high-strength steel casing, rebar and grout.

Micropile systems are preferred to support and stabilize buildings, bridges, highways, towers and other man-made structures, either as new foundations or remedial construction. They are also frequently used for underpinning and shoring applications due to their high load capacity and flexible installation techniques.
