  2. Flush and Inspect pipeline for line obstructions and condition
  3. Pipeline preparation and bypassing flow
  4. Liner and Equipment Preparation
  5. Steam PVC Folded Pipe to soften liner
  6. Pull liner through host pipeline
  7. Heat and Pressurize Liner until liner flares to host pipeline
  8. Cool and Harden liner
  9. Trim liner to the host pipeline
  10. Final Video Inspection

Large Pipe Lining SPR™ PE

The   SPR™ PE  liner is spirally wound into a circular pipe from within the base of the manhole of the pipeline to be rehabilitated. The liner is introduced into the annular space and is subsequently grouted using a cellular, low strength cementitious grout.    Can be installed in live flow conditions based on worker safety and other considerations. Other flow management techniques can be used to eliminate the need for onsite bypassing.
