Spot Repair

An Epoxy mixture is saturated onto a mat composed of fiberglass, it is then wrapped onto an inflatable bladder and inserted into the pipeline to the exact damaged location. The bladder is then inflated to the proper pressure level to adhere the repair to the pipe. The bladder is a ” flow through” which means it allows continual usage of the line during the repair.

After the proper cure time ( usually 2 hours) the bladder is deflated and then removed leaving a fully structural and watertight repair behind.

Benefits of CIPP Spot Repair

Reduced Cost: Cipp sport repair reduces the higher financial cost of conventional methods of pipe line repair.
Long life span: Minimum life span of a CIPP repair is 50 years
Ease of installation: With CIPP point repair installation, the liners can be installed without any service interruption. A complete job can be finished within a matter of hours.

No Digging: No need to cautiously dig while maneuvering around various utilities and infrastructure.
Environmentally Friendly: Eliminates soil disruption, air pollution, asphalt removal and replacement and emissions produced by heavy machinery.
Hydrophobic resin options allow for sport repairs to be completed in the presence of water even under pressure of gushing infiltration.

Size of Pipe we can rehabilitate using our spot repair system 2 inch – 12 inch. From 2 to 15 feet.

Mainline Manhole to manhole CIPP Repair

Cured-in-Place-Pipe (CIPP) lining is a method of trenchless rehabilitation and restoration used in the repair of existing pipes. CIPP lining uses a textile liner tube and a liquid resin.

The process begins with the wet-out stage. During this stage, the textile liner is impregnated with the resin mixture, an epoxy base with a pre-determined hardener.

Next, the liner is inverted into the pipe with air pressure. The resin will now be on the outside of the liner against the existing host pipe wall.

After inversion, a calibration tube is inverted inside the liner which can then be ambient, hot water, or steam cured. During this period, the curing agent activates the resin causing it to harden, creating a fitted, smooth, and corrosion-resistant new pipe wall.

If necessary, a robotic cutting device will be inserted into the newly lined pipe to reinstate any lateral service connections.
