NCDOT Slip Line Project in Chapel Hill, NC
NCDOT Alamance Bridge Maintenance slip lined an existing CMP pipe that was under a major street in Chapel Hill near the University of North Carolina. The existing culvert was corroding in the invert section of the pipe. An Aluminum Ultra Flo Pipe with Internal Fange Joints was used to reline the existing culvert which was installed by NCDOT Bridge maintenance forces. The annular space between the new liner pipes and existing culvert were grouted using the fabricated grout ports that were installed on the liner pipes.
