JANSSEN FAST-INJECT: Rehabilitation of Lateral Connections and Joints

Injection Process For The Connection of Laterals in Relined Pipes and Joint Repairs

  • Materials of Main: Clay, Concrete, PVC and Cast Iron
  • Materials of Liner: GRP, Needle Felt

Janssen Fast Inject is a novel Process to quickly and durably re-connect laterals to a relined main and for the sealing of leaking joints.

The 2-component PU based resin is pumped from separate tanks on the service vehicle to the packer, where it is mixed and immediately injected into the repair area. The fast curing resin allows repairs in only a few minutes, so that the function of the lateral connection ist interrupted only briefly. The working principle guarantees a force-fit connection.
