Submit-grouting within the bond size can increase frictional forces with bordering soils and accomplish greater capacity. Micropiles can provide to “stitch” the soil together within predicted shear zones to boost mass stability. In liquefiable profiles, micropiles can transfer loads to capable bearing strata to comply with seismic design demands.
