Write-up-grouting inside the bond size can enhance frictional forces with bordering soils and attain increased potential. Micropiles can provide to “sew” the soil alongside one another in predicted shear zones to enhance mass balance. In liquefiable profiles, micropiles can transfer masses to capable bearing strata to observe seismic structure needs.
