The Triplex Liner System Is the Permanent Fix
The Triplex Liner is not a coating. It is a new structural wall of fiberglass and a continuous corrosion barrier, cured in place inside the existing structure. The structure gets its strength back and keeps it.
The system has been patented, proven in service, and designed and tested to last up to 100 years in sewer conditions.
It is installed in cities across the United States, Canada and Australia.
America's Underground Infrastructure Is Falling Apart
Every city runs on infrastructure nobody sees: manholes, lift stations, wet wells. Sewer gas eats the concrete, and years of corrosion end in leaks and lost strength. Cities have spent decades paying for temporary fixes to a permanent problem.
How It’s Done
Every liner is measured against the structure it will repair and custom built at our factory. On site, the work moves fast: the structure is prepped, the liner is cured in place, and the structure returns to service. For a typical manhole, installation is completed in a single day.
Engineers can request the full specification package. The disruption a city fears from rehabilitation is the part we engineered out.
Measured and Built
Every liner starts at our factory in Northwest Florida, custom built to the measurements of the structure it will repair, in two pieces: the shaft and the bottom disc.
Prepped and Installed
On site, the structure is cleaned back to sound wall. The crew saturates the liner, lowers it in, presses it into full contact with the structure, and cures it in place with steam and air.
Back in Service
The inlets and outlets are cut and reopened, and the structure returns to service with a new structural wall inside the old one. Installation for a typical manhole is completed the same day.
Do It Right Once
Temporary fixes like spray-ons and coatings protect a surface for a short time. Real rehabilitation requires the Triplex Liner: the structure gets its strength and its corrosion protection back in one operation.
That is why cities that have tried both specify the liner. It turns a maintenance cycle into a finished repair.
Built for the Toughest Jobs
Deep, in freezing temperatures, in the middle of Edmonton, Alberta. Some structures are critical to a city's health and nearly impossible to take offline: deep, downtown, on streets that cannot close. That is the work this system was built for. The liner goes in through the opening that is already there, one piece, built for that structure, and the street is back the same day.
Working in Maine
Maine municipalities and consulting engineers specify structural lining for manholes, lift stations and wet wells across the state. If your district is planning rehabilitation work, we can walk a project from evaluation to specification to installed liner.
Working Across Maine
Where We Take Projects in Maine
We have not lined a structure in Maine yet, and we are open to the first one. Portland, Lewiston, Bangor, West Scarborough, South Portland, South Portland Gardens, Auburn, Biddeford, Sanford and Saco, and the districts and authorities between them.
What Maine Asks of a Combined System
For Maine communities licensed with combined sewer overflows, a discharge is only acceptable if it comes from wet weather beyond the system's design capacity. A discharge caused by mechanical failure, improper design or inadequate maintenance is not, and the community evaluates its system to find the extraneous water getting in.
A duty that recurs rewards work that does not. A structure that has been rebuilt from the inside comes off the list; a structure that has been recoated comes back around on the next cycle. The Triplex Liner is a new structural wall and a continuous corrosion barrier, custom made for the structure and cured in place inside it.

Go →Questions We Get in Maine
Do you line lift stations and wet wells, or just manholes?
Both. Manholes are the core application, and lift stations and wet wells are lined with the same system.
We have used coatings before. What changes?
A coating depends on the wall underneath it. The Triplex Liner is a new structural wall, cured in place inside the old one, with the corrosion barrier built into it.
What is the service life?
Up to 100 years in sewer conditions, designed and tested. The warranty is twenty years on manholes and ten years on lift stations and wet wells.
Do you self-perform the work?
Installation is carried out by contractors licensed and trained on the system. Send us the project and we will connect you.
Do you work outside the United States?
The system is installed across the United States, Canada and Australia, and we welcome enquiries from anywhere.
