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.
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.
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 Nevada
We work with Nevada municipalities, utility districts and consulting engineers on manhole, lift station and wet well rehabilitation. If rehabilitation is in your capital plan, we can help scope and specify it.
Triplex Liners in Nevada
Nevada has Triplex Liner work behind it, since 1994. Every one of them was made at our plant in Northwest Florida, built to the measurements of the structure it was going into, and cured in place inside it.
Cities in Nevada With Triplex Liners in the Ground
Las Vegas, Fallon, Lake Mead, Laughlin, Fernley, Tahoe, Lake Mahave, Overton and Reno.
Where We Take Projects in Nevada
We take projects across the state. Henderson, North Las Vegas, Paradise, Sunrise Manor, Spring Valley, Enterprise, Sparks, Carson City, Whitney and Pahrump, and the districts and authorities between them.
What Nevada Asks Before You Build
Nevada reviews collection and treatment design against the regional recommended standards by rule, and engineering plans covering sewage collection, sealed by a professional engineer, must be submitted to the state before construction.
The structure keeps its location, its size and its connections. What changes is that it has a new structural wall and a continuous corrosion barrier inside it, made for that structure and cured in place.

Go →Questions We Get in Nevada
Does the structure have to come out of service?
Usually for no more than a single shift. Most manholes are lined and returned to service the same day.
Can it go in where the structure is still leaking?
In many cases, yes. A standard installation handles active leaks roughly ten to fifteen feet down, and about twenty feet of head pressure is the practical limit of the traditional method. Severe infiltration, or a structure that has begun to collapse, calls for other measures first. The real limit depends on ground conditions, the water table and the depth of the structure.
How is this different from an epoxy or cementitious coating?
A coating protects a surface. The Triplex Liner is a structural wall with its own corrosion barrier, cured in place inside the existing structure.
How long does it last?
The liner is designed and tested to last up to 100 years in sewer conditions. Manholes carry a twenty-year warranty, and lift stations and wet wells carry ten years.
Is the system available internationally?
Yes. It is installed in the United States, Canada and Australia, and we welcome international work.
