Injection Process for the Reconnection of Laterals to lined or main sewer pipes and Point Repairs. Janssen Fast Inject is a novel process for the quick and permanent reconnection of laterals to lined or main sewer pipes as well as for point repairs. A 2 component PU resin is pumped from a service vehicle to a packer, where it is mixed immediately before reaching the point of repair, where it is injected into the defect area.
