Our diverse fleet and team of experience marine personnel execute and support for dredging, lighterage and barging of aggregate materials in multiple locations.

Foss supports dredging customers in San Francisco Bay, along the U.S. West Coast, or anywhere a customer may require. As a U.S.-flagged Jones Act company, we can provide support for both U.S. and international companies.

We offer:

  • Point to point transportation and towing services of deck barges, crane barges, dump scows and equipment, and
  • Engineering and project management, as required.


Foss actively supports companies in the Bay area in sand mining operations on specified areas leased primarily through the state of California. With dedicated resources we extract fill and coarse sand from the San Francisco Bay, with regular deliveries to yards in the Port of San Francisco and the Port of Oakland.
