Micro piles 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. Micro piles are comprised of high-strength steel casing, rebar and grout

Micro piles, also known as mini piles, pin piles, needle piles, and root piles, are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.

The first thing you need to do is dig a deep hole with a small diameter. Once you've cleared the space for the pile, you can lower that into the hole and apply torque to secure the pile. Then you fill the hole with a concrete grout mixture to keep everything in place.
