The newly developed and patented Janssen Lateral Rehabilitation System provides for a one step simultaneous repair of the joint between the lateral and the main pipe while at the same time repairing any damage within the lateral and the main pipes.

The Janssen Lateral Rehabilitation System consists of a packer with a side opening from which an inflatable piston guided by tv cameras is extended into the lateral connection. Packer and the side piston are then expanded to the cross section of their specific pipe. The side bladder extends deep into the lateral pipe and forms a homogenous T with the packer in the main pipe. The resin is then injected and seals any cracks, holes, breaks, or the like. The cross section is fully maintained. Any voids in the soil around the pipe are filled with the hardening resin, thus solidifying the soil and guaranteeing the structural integrity of lateral and main pipe.
