A stormwater pipe made of part clay, part corrugated metal and part cast iron, failed under a Light Rail commuter line in Baltimore. Using a pipe swallowing technique, AEI implemented a TT Technologies Taurus Pipe Rammer to install a new 60” diameter steel casing over the collapsed pipes. Original host pipes were removed with winches, tunneling methods and an auger bore machine. The 36” Snap Tite liner pipe was installed through the casing and a lightweight cellular grout was pumped in the annular space between the casing and the carrier.
