RELINING PROCESS

RELINING PROCESS STEP BY STEP

1. Clean

Video inspect and clean the inside of the line to see the extent of the damage and length of the line that will need to be rehabilitated. Roots are then cut and all debris is removed by water jetting.

2. Prepare

A fabric tube with flexible PVC coating on the outside and felt on the inside called a liner is measured and cut.  An epoxy mixture is used to saturate the inner felt fabric of the liner.

3. Invert

The end of the liner is rolled up inside an inverter unit which forces air into the pipe liner, shooting it down and turning it inside out so that the smooth PVC lining is on the inside and the resin-saturated fabric is pressed against the existing pipe.

4. Bond

A tube called a calibration tube is then shot down the inside of the new PVC liner. The calibration tube is maintained at constant pressure in an inflated state in order to create a bond between the original pipe and the new PVC line.

5. Cure

The resin will harden after a few hours and the calibration tube will then be extracted, leaving behind a hardened, new seamless PVC line on the inside of the original pipe.

6. Inspect

The new line will eliminate gaps and cracks along with any tree roots that were creating blockages in the old pipe. This new PVC pipe is referred to as a ‘cured-in-place’ pipe liner. Once the pipe is cured and is all set to go, a final video inspection is done to confirm the success of the new pipe.

Cured­-in­-place Pipe Lining has recently gained popularity, yet it was first commercialized in the U.S. in the mid-1990’s. CIPP was invented in England in the 1970’s and it’s widely used in Europe today.

Clear Pipe is one of the pioneers in trenchless lining technology in the North Shore.
