Rehabilitiating the Brooklyn Bridge Manhattan Approach Arches using Jet Grouting: Project by Keller Featured

Keller team is working on the iconic Brooklyn Bridge in New York City, using jet grouting to rehabilitate the Manhattan approach arches. Mobilization began in May 2020 and production is expected to finish in Fall of 2021.

Working amid the pandemic, “COVID-19 travel restrictions have required our team to accept support from the greater Keller organization through virtual methods. With the benefit of technology, the support has been effective, providing a higher degree of competency for the project team.”, Keller Senior Project Manager James Myers states.

Keller's jet grouting technology allows for real-time quality control provided wirelessly to the drill from the grouting station, while maintaining precise construction parameters. Column data reports and real-time raw data are provided to the client for verification and deeper analysis. By overlaying the design drawing with constructed production elements, installed elements can be visually verified.

Advantages of Jet Grouting

Effective across the widest range of soil types of any grouting system, including silts and most clays
Ability to construct soilcrete in limited spaces and around subsurface obstacles such as utilities
Low headroom equipment enables construction in limited spaces such as basements
Can target specific soil layers at depth without having to treat soils above
Jet grouting can be combined with other techniques to provide a comprehensive and cost-effective geotechnical solution
Can usually be done without disrupting normal facility operations
Containerized, highly mobile support equipment reduces mobilization and demobilization costs and time
