Sliplining

The process by which an appropriately sized liner pipe is inserted into an existing pipe.  The new pipe can be pulled in place using a cable and winch system, or pushed in place using a choker cable and backhoe.

ADVANTAGES

  • Minimal surface disturbances
  • Replace existing pipe with a completely new pipe
  • Uses existing easements and alignments

CONSIDERATIONS

  • Grade will match any existing bellies or high spots
  • Service connections require separate excavations
  • Bypass or temporary service might be required
  • Cannot use on a collapsed pipe
  • Cannot increase diameter
  • Existing pipe must be relatively clean with no fittings/obstructions
