New Foundation Installation In Zero Lot Line Conditions

Problem:
Installation of new foundation on zero clearance lot in San Francisco, where excavation undermined neighbor’s foundation.

Solution:
It was necessary to underpin neighbor’s foundation with hand dug piers, before excavation commenced. Then a new foundation with retaining walls was installed using shotcrete.

Result:
New foundation was ready for home construction, free of earth settlement issues with neighboring properties.
