GROUTING SLEEVE™ and Sewer Sealer™ 

Sleeve Installation procedure:

A REPAIR SLEEVE comes in a package containing complete supplies including the right amount of sealant ready for installation. Before Installation please read installation tips enclosed into shipping box.
The SLEEVE is placed on the sewer plug.
Step #1: The SLEEVE is placed on the sewer plug.
The grout is worked into gasket first under the overlap Flap.
Step #2: The grout is worked into gasket first under the overlap  Flap.
Rubber bands are then pulled over the flap to hold the overlap securely in place while the SLEEVE is being transported through the pipe.
Step #3: Rubber bands are then pulled over the flap to hold the overlap securely in place while the SLEEVE is being transported through the pipe.
The rest of the gasket is then filled with grout. Grout must be applied evenly. The Grout is easily absorbed and may leave some part of the gasket empty if not carefully and evenly spread. This will cause the failure in sealing.
Step #4: The rest of the gasket is then filled with grout. Grout must be applied evenly. The Grout is easily absorbed and may leave some part of the gasket empty if not carefully and evenly spread. This will cause the failure in sealing.

 NOTE: All grout provided with the SLEEVE should be used up. For better seal, white end sealer are also painted with grout.

 
The SLEEVE is centered on the plug and the label inside the sleeve should face upwards. The plug is then inflated very slightly to hold the SLEEVE firmly on the Plug.
Step #5: The SLEEVE is centered on the plug and  the label inside the sleeve should face upwards. The plug is then inflated very slightly to hold the SLEEVE firmly on the Plug.
CCTV camera is often connected to the Plug cable looking back at the SLEEVE/plug assembly as it is pulled into the pipe.
Step #6: CCTV camera is often connected to the Plug cable looking back at the SLEEVE/plug assembly as it is pulled into the pipe.

Step #7: CCTV camera being passed into Access Chamber (Manhole)
The SLEEVE usually follows the inspection camera.
Step #8: The SLEEVE usually follows the inspection camera.
Down in the Access Chamber CCTV camera and SLEEVE are received and passed into the pipe.
Step #9: Down in the Access Chamber CCTV camera and SLEEVE are received and passed into the pipe.

NOTE: At 23°C (73°F) the Grout starts curing in approximately 20 minutes from the time it came in contact with water.

Step #10: Schematic showing SLEEVE  being pulled to the repair location.
On the CCTV monitor the entire  installation process can be followed.
Step #11: On the CCTV monitor the entire  installation process can be followed.
The SLEEVE  arrives at the location of damage.

The SLEEVE Should be installed before the Grout cures.

Step #12: The SLEEVE  arrives at the location of damage. To install the sleeve, bring the air pressure to about 10 to 15-psi above “Calibration pressure”. (Note: Calibration pressure of a Link-Pipe Plug is the pressure required to expand the plug so that it makes contact with the host pipe wall). 

Release the air pressure and check by camera if all locks are engaged.

NOTE: 

  • If some locks are not engaged, insert the plug again, move the plug to the unlocked end of the sleeve and apply 5 psi more pressure and repeat the installation.
  • The SLEEVE Should be installed before the Grout cures.
POST-INSTALLATION QUALITY CONTROL Step #13: POST-INSTALLATION QUALITY CONTROL

The project is considered completed when:

  • All enclosed grout is used up

  •  

  • All damaged pipe is covered with the SLEEVE

  • Before removing the CCTV camera from the pipe check that all SLEEVE locks are engaged.
