Pier 70 Historic Core Revitalization
The revitalization of San Francisco’s Pier 70 Historic Core stands as a landmark project in adaptive reuse and sustainable urban redevelopment. Originally home to Bethlehem Steel and Union Iron Works, the site’s transformation focused on preserving its rich industrial legacy while adapting it for modern public use. As part of this restoration, the cobbled streets required a jointing solution that could handle high foot and vehicle traffic, allow water permeability, and withstand intensive cleaning routines. ROMEX was chosen to supply the jointing mortar for this demanding environment.
PRODUCT SELECTION
To meet the project’s performance demands, ROMEX D2000 jointing mortar was selected. This heavy-duty, highly durable mortar is specifically formulated for high-traffic areas like public streets, plazas, and commercial walkways. Its resistance to erosion, weed growth, and mechanical cleaning made it an ideal fit for this urban setting. D2000’s permeability also allowed it to meet sustainability goals by supporting stormwater drainage.
PROJECT LOCATION
Pier 70 – San Francisco, CA
Once a bustling industrial shipyard, Pier 70 is now a model of historic preservation and environmental design. The restored five-acre site includes over 300,000 square feet of repurposed buildings, blending original materials with modern interventions to create vibrant public and commercial spaces.
PROJECT NEEDS
The City of San Francisco required a paving solution that could:
- Withstand heavy vehicular and pedestrian traffic
- Maintain durability over time
- Allow for regular street cleaning and power washing
- Prevent weed growth in cobble joints
- Provide stormwater permeability to align with green building goals
The jointing solution had to integrate seamlessly with the project’s emphasis on sustainability and long-term performance in a coastal environment.
PROJECT SOLUTION
Approximately 5,000 square feet of cobbled street surface was treated using ROMEX D2000 jointing mortar, applied between stones set in mortar. The product’s high mechanical strength enabled it to handle both foot and vehicle traffic with ease, while its permeable nature supported drainage and reduced surface runoff. By locking cobbles in place, D2000 also prevented weeds from accumulating in the joints—enhancing the longevity and cleanliness of the restored streets.
This application supported the broader environmental and preservation goals of the project, which was led by a collaborative team including Marcy Wong Donn Logan Architects, GLS Landscape Architecture, and Orton Development Inc., for the Port of San Francisco. The result is a durable and visually cohesive streetscape that honors the past while supporting the future of the Pier 70 district.
