The Job
Sparrows Point, in Baltimore, Maryland is a brownfield site being redeveloped from steel manufacturing to industrial and logistics use. From it says as a heavy manufacturing facility, there is an extensive freight rail network throughout the site, with many grade crossings subject to significant heavy truck traffic & heavy haul rail traffic.
The Challenge
A precast tub-style grade crossing on a road feeding a metals recycling plant developed a 2.5″ belly. The local FRA inspector instructed the railroad to correct the settlement.
The Solution
CJGeo performed structural polyurethane grout injection to fill voids below the panels, and then lift them back into their correct alignment. The work was completed in a few hours, without disruption to the rail or auto traffic.
