San Francisco, CA
Today we rewind time to 1986 to our Jefferson Street Sea Wall Project
The Port of San Francisco wanted to fill void space behind the seawall under the sidewalk between Tarantino’s and Castagnola’s restaurants. The point of this project in 1986 was to raise the sidewalk or actually build a new sidewalk up at a higher elevation and fill in between the old lower and new higher sidewalk with Lightweight Cellular Concrete (LCC).
The project team chose Lightweight Cellular Concrete (LCC) to fill the void space behind a new sheet pile wall. Since the LCC was partially underwater, the lower submerged LCC unit weight was 65 pcf and it was placed by tremie methods.
