Also called mini piles, micro piles are used for underpinning. They are normally made of steel of various diameters and are ideal for use in low headroom or otherwise restricted areas and for specialty or smaller scale projects. Hollow bar shafts are left in the ground via a sacrificial bit and grout displaces the soil as it is extracted. Micro piles are often grouted as shaft bearing piles but non-grouted micro piles are also common as end-bearing piles.
