Post-grouting within the bond duration can boost frictional forces with encompassing soils and achieve larger capacity. Micropiles can serve to “sew” the soil jointly within predicted shear zones to boost mass steadiness. In liquefiable profiles, micropiles can transfer loads to proficient bearing strata to adhere to seismic design necessities.
