Vibration-free helical underpinning stabilizes a Jersey City brick building damaged by nearby pile driving
After H-pile driving next door caused settlement at 304 Johnson Avenue, a historic four-story brick building, engineers ruled out driven piles and drilled shafts because of low headroom, high groundwater and collapsing soils. Danbro describes the fix: 20 IDEAL 4.5-inch heavy-wall helical piles advanced in short sections to bearing at about 55 feet.
