eLINER is a technology developed to rehabilitate sanitary drains lines by fixing them from the inside out.
In the old days, the only cure for cracked and failing drain lines was to tear open walls and floors to replace the piping, a very messy, time consuming and costly method. “Continuous Air Inverted eLINER Pipelining” is the wave of the future. Continuous Air Inverted eLINER lining is a straight forward concept. A felt tube constructed of interwoven fibers and coated with PVC gives the liner structural stability. A two part epoxy resin is then introduced to the material and evenly distributed. This process is referred to as “The Wet Out.” The continuous liner is then inverted into the host pipe by “Air.” Unlike the spotty adhesion problems of pull in place liners, FPS utilizes the Air Inversion eLINER process.
The lining material is literally turned “Inside out” during installation, allowing the resins to now make 100% contact with the host pipe. Once this full length continuous liner is in place, a bladder-like calibration tube inside of it is inflated to a sufficient pressure to compress the liner against the host pipe. This allows a 100% water tight seal as it fills cracks, holes and splits in the host pipe. The resins then “set up” and harden during the “Curing” process. Once the Curing process is complete, the bladder is then deflated and removed. Rather than merely having sections of your pipe lined, like the stop and start method or the problems of pull in place liners, this Air Inverted continuous eLINER Liner is a “pipe within a pipe” forming a continuous full length and STRUCTURAL repair. The laterals are now re-instated by an optically guided robotic cutter. After completion, the client now has a continuously lined pipe from top to bottom that will last for many years to come.
Yes. The liner can be inserted through a cleanout or from a small excavation and the end of the liner is open so there is no need to access the other end of the liner.
By use of an optically guided robotic reinstatement cutter.
At ambient temperatures the liner can be cured in 4-6 hours or less. Hot air or steam can hasten the process.
There is no cutting required because the bladder extends beyond the end of the liner keeping the end of the liner fully open.
On average 4 to 6 laterals can be renewed in one day.
Pipes from 2” to 48” diameter.
Up to 130’ of 4” liner or 100’ of 6” liner can be inserted through single installation.
There is a minimal reduction in diameter, but the smooth bore interior of cured in place pipe typically improves flow rate. Also, pre-cleaning typically removes encrustation that has restricted flow.
The Liner system is often used to renew roof drains, industrial piping, commercial piping, and residential drain and waste piping.
How do you verify the bond between the liner and the host pipe? No manufactured CIPP product or installation contractor can tell you when the liner sticks and how well it is stuck to the pipe. There is grease in sewer pipes which has a serious effect on adhesion. However, wherever the pipe is thoroughly cleaned good adhesion will occur.
Yes, the lateral liner is a new pipe within a pipe so there are no open joints, cracks or crevices where roots have an opportunity to grow.
The liners have an engineered service of 50 years based on ASTM F1216-09. The service life is based on extrapolation of testing data of the liner’s physical properties.
