Premier Trenchless Sewer Renewal
T- Liner mainline lateral interface seal and full-length lateral lining
The best solution to seal out inflow and infiltration at the main to lateral connection.
We fix these problems
Our common solutions
Overtime Joints separate and allow groundwater to infiltrate the collection system which ultimately causes treatment plants to go past capacity and additional money needs to be spent on overages and upgrades.
Localized cracks and fractures weaken the main lateral interface which weaken the pipes integrity and may lead to progressive collapse which necessitates traditional excavation at great expense in the roadway.
Roots and chemical corrosion penetrate joints or cracks and cause expensive backups and lead to structural degradation that ultimately leads to collapse and pipe excavation.
Seals and reinforces the joint preventing leaks and inflow and infiltration(I&I)
Restores pipe strength at the defect without having to replace the full pipe.
Seals the main to lateral interface from root intrusion and prevents any I&I from occurring at the main to lateral interface.
Our T Liner Solution
The T-Liner system rehabilitates sewer laterals by forming a continuous CIPP liner that extends from the mainline into the lateral pipe from as little as 12 inches to up to 140 feet. At the mainline interface, the system utilizes patented hydrophilic O-rings that expand upon contact with water to create a positive, watertight seal. This proven sealing mechanism is the only method that delivers a true seal at the lateral-to-mainline connection, effectively reducing infiltration while the jointless CIPP liner provides a full structural replacement of the existing lateral pipe.
The NoVa lining process for T-Liner Installation
1. Inspect, Clean, Measure and Prepare
- CCTV inspection identifies the defect at the main to lateral connection
- Nova thoroughly cleans the sewer lateral and mainline using the most effective access point—either from the mainline or the lateral—based on available cleanout access. This preparation ensures optimal conditions for successful T-Liner and CIPP sewer rehabilitation.
- Pipe is cleaned to remove roots, debris and buildup
- defect locations are verified and approved for lining
- Precise measurements are taken so that the liners can be manufactured/acquired.
- Mainline Liners have been installed so that lateral interface and lateral now need to be sealed.
2.Receive Materials and Put out notices to residents and communicate plan to municipal inspectors and/or engineers
- Nova Lining shall coordinate with the Municipality to provide advance notification of the proposed installation schedule and to confirm that no water service interruptions will be required for the laterals included in the work.
- Prior to installation, our team notifies affected residents by placing door hangers at each property, advising them of the scheduled T-Liner installation and asking that water use be avoided during the work.
3.Crew Arrives and Readies the Job site
- Crews will knock on all doors and let residents know not to use water as applicable
- Nova will setup equipment and put out any necessary traffic signs etc.
4. T liner positioning device and Liner are prepared
- The Positioning device (also referred to as a packer) is prepared as the liner is saturated with the appropriate resin.
- Once the liner is saturated with resin and adhered to the positioning device prior to being launched into the main
5. T Liner is Launched into the main
- Once launched into the main pipe, the device is pulled into the exact location and with the help of a camera positioned in such a way that the packer is exactly lined up with the lateral pipe.
- Once in position the T liner is inflated and the main to lateral connection is lined
- Once curing is complete the positioning device is removed and the main to lateral is inspected
need an image of the packer being positioned as seen from the camera
6. Final Videos are made and submitted to the client
- Final videos will be made and sent to the client for payment.
- Warranties and all project tracking is shared with the client.
- this includes our warranty, final video
