In piling, a self drill micro pile is one of many forms of Mini Piling. A self drill micro pile uses a hollow threadbar with a sacrificial drill bit which is drilled into the ground using grout as a flushing method. This results in a grout body within the ground containing a high tensile steel bar.
Self drill micro piles are effective in a variety of ground conditions, including gravel, clay, rock, sand and made ground. This method of mini piling is used in a wide range of projects including rail related work and foundation upgrades, stabilisation and underpinning as well as facade retention, tension piles, road works and bridge works.
Step 1: Set up with drill bit at Pile position.
Step 2: Drill and inject grout simultaneously.
Step 3: Drill to desired depth using couplers to add extra lengths of threaded hollow bar as necessary.
Step 4: Secure anchor plate with two load bearing nuts and cast into concrete beam.
