Site:
Kokoro Theatre/Assisted Living Facility, San Francisco, California

Problem:
For this Historic Landmark the planned conversion from theatre to an assisted living facility required certain excavations under and in close proximity to the existing foundations. The new added loads would have initiated certain settlements that could not be permitted for the structure.

Solution:
Although there is more than one way to approach and resolve such construction problems, chemical grouting was chosen to mitigate the anticipated problem. A pure chemical – permeation system was selected and proved to be successful in mitigating these problems.
