Amityville, NY Residence

Danbro assisted the engineer, Jeffrey Havelin, PE, in recommending an economical solution by preserving the original foundation, and using underpinning brackets and our 1 1/2″ helical piles to underpin and anchor the existing foundation for this house lift.
The high water table, especially during high tide, proved challenging when installing the pile terminations and underpinning brackets. High Rise Industries used a dewatering system in order to gain access below the existing foundation in order to attach the brackets.
