Write-up-grouting within the bond size can increase frictional forces with surrounding soils and obtain higher capacity. Micropiles can provide to “sew” the soil collectively within predicted shear zones to reinforce mass stability. In liquefiable profiles, micropiles can transfer loads to knowledgeable bearing strata to stick to seismic design requirements.
The timber pile foundation of your century-previous Prairie du Sac Dam was deteriorating resulting from historic tailwater recession. Micropiles have been mounted in a variety of diverse combos to remediate the dam's foundation.
