The foundation is the most essential part of any building or structure; the foundation is the base structure that transmits loads from a building to the ground. Suffice to say the foundation is the most important part of a building's structure, particularly in seismically active California.

PROJECTS

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.
