Janssen Process Point Repair Fortifies Mainlines

Contractors prefer Janssen because it:

Installs with 0% failure rate (no excavation)
Uses equipment and consumables that are competitive with less-durable solutions.
Lasts the longest, making repairs easier and less expensive to warrantee.
Generates daily margins that are up to triple those of conventional rehab technologies.
Requires fewer crew members.
Uses materials that are more stable and easier to handle.

Cities prefer Janssen because it:

Doesn't diminish a pipe's inner diameter.
Structurally addresses pipe deterioration by bonding cracks and filling voids.
Permanently solves infiltration, root intrusion and ground cavity problems.
Requires no line plugging.
Prevents future sink holes.
Doesn’t interrupt traffic.

Pressure-Injected Resin Fills Cracks and Reestablishes Bedding without Reducing Pipe Diameter.

Janssen Process offers strength and support to deteriorating mainline sections. Fast-curing resins are robotically pressure-injected into pipe cracks, bonding them and filling any cavities around the mainline to eliminate root intrusion and infiltration.

Using Janssen Process, a single truck performs up to 10 point repairs per day. No line plugging or traffic disruption is required, and a 0% installation failure rate means excavation is never necessary. Repair longevity has been documented to 25 years, but is estimated to be 60-80 years. While far more durable than other point repair rehab methods (and thus easier to warranty), this Janssen Process remains cost-competitive in terms of both capital equipment and consumables.
