Industrial Short Line Tub Crossing Repair

Baltimore, MD

The Job

This short line tub crossing repair project is located in Baltimore, Maryland. Sparrows Point, in Baltimore, Maryland is a brownfield site. It’s transforming from being 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 took just a few hours, without disruption to the rail or auto traffic.

CJGrout 40NHL is a four pound per cubic foot geotechnical polyurethane grout. It’s specifically designed for high dynamic load environments like rail, port, and airfield traffic. CJGeo’s crews use 40NHL for modular grade crossing repairs to ensure the longest life repair possible.
