Wet Soil Mixing in California Featured

Many sites in California are located near fault zones and are underlain by liquefiable soils which can result in excessive settlement and lateral spreading in the event of an earthquake, putting structures and their occupants at risk. The site of the planned Community Memorial Hospital in Ventura, Calif., is one such site. Ground improvement was recommended in order to mitigate liquefaction potential and allow the new hospital to be supported on shallow spread footings.
