The Janssen Process
Janssen technology is the only no-dig remedy addressing the underlying cause of lateral connection failures: inadequate bedding and structural support.
The Janssen system rebuilds proper bedding around the
connection to permanently eliminate operational problems such
as broken pipe, root intrusion or groundwater infiltration.
Fast curing resins are robotically pressure-injected into the cavities around a lateral, creating bedding that permanently eliminates root intrusion, infiltration and voids. It also seals the liner to the mainline at the lateral interface, preventing seepage between the two. The entire process is completed in just a few hours and requires no line plugging or digging of any kind. The structural integrity of the connection is restored and the service connection is renewed.
