How this node works

A reinforced-concrete cap embraces the existing footing, tied to it by drilled-and-grouted dowels; from the cap a pair of inclined micropiles descends, so the old foundation is «hung» on the new piles and the load reaches firm soil at depth.

  • Existing footing
  • Connecting cap
