Documentation is made of the damaged section. All roots, debris and protruding service connections are promptly removed.

A pre-measured amount of resin and catalyst is provided for the liner according to its diameter, length and thickness.

The resin is introduced into the tubular liner and stays totally contained. This ensures quality control for the remainder of the process.

The liner is vacuum impregnated, allowing the tube to be fully saturated with resin. This eliminates air pockets, providing a thorough wet-out that can be inspected visually by the installer.

The resin saturated tube and inflation bladder are inserted into a carrying device that transports the liner through the pipeline to the point of repair. The resin, which provides the structural seal, is protected and does not come in contact with the pipe until it reaches the point of repair.

The carrying device is then introduced to the pipeline through a standard manhole opening. This is accomplished by a single technician without the need for hoisting devices.

The carrying device is then positioned at the beginning of the repair and inverted through the damaged section. Continual documentation is performed as the liner conforms to the host pipe. The CCTV monitors the placement of the liner, reassuring lining consistency.

The bladder is reverted from within the cured-in-place pipe. This enables the installer to inspect the liner for a proper cure at any time, without risk of damaging the liner. The launcher and inflation bladder are removed and a final inspection is performed to document the proper opening of service laterals and the integrity of the seamless pipe.
