How the InnerSeal™ Innerwrap™ System Works

Step 1: The InnerSeal™ Innerwrap™ Skeleton Assembly

Resin impregnated liner attached to InnerSeal™ Innerwrap™ skeleton.

A pre- manufactured, needle punched felt liner material made to match the geometry of the service connection is impregnated with a two-part 100% solids epoxy resin. The liner material is then positioned inside the skeleton exposing the InnerSeal™ Innerwrap™ connection liner.

Step 2: The InnerSeal™ Innerwrap™ Skeleton is Positioned at the Service Connection

Skeleton is attached to an articulating robot which will line up the main bladder with the service connection.

A winch pulls the skeleton through the main line to the service connection to be repaired. An articulating robot precisely aligns the independent main bladder opening so that it is directly facing the service connection.

Step 3: The Sealing Process

Independent lateral bladder inflates out of the main bladder, inverting the InnerSeal™ Innerwrap™ liner into the service connection.

The independent lateral bladder is air inverted into the service connection. The specially formulated resin is allowed to cure with or without the use of external heat.

Step 4: Completion of the Installation

The independent lateral bladder and main bladder are deflated and the positioning tool removed from the main line. Repair of the defective connection is complete. The process results in a watertight service connection seal and a structurally sound, solid connection with a minimum life expectancy of 50 years.
