Micropiles have a small diameter and are drilled through soil and/or rock and reinforced with a high-strength, grouted bar. Micropiles piles can be fully cased, partially cased, or uncased, depending on the soil and rock conditions. This foundation type creates very little vibration and noise compared to traditional pile driving and can be used in sites with limited access, achieving very high capacities in compression and tension.
