60-Degree Slope Pipe Rehabilitation

This project consisted of the rehabilitation of a pipe with over a 60-degree slope.  The steepness of the slope made everything from cleaning to installation challenging. Technicians needed to be rappelled down the pipe to complete the rehabilitation work.  Our team scrubbed heavy tar out of the pipe prior to lining and completed the job with excellent results.
