Stop Paying for the Same Manhole Twice
A city that coats a manhole owns that manhole again in a few years. The work comes back around, the crew goes back out, and the budget line never closes.
A structural liner ends the cycle. It is structural fiberglass bonded around a continuous non-porous membrane, fabricated for the one structure it repairs and cured in place inside it, and it is designed and tested to last up to 100 years in sewer conditions.
Spend once, on the structure you already own.
What a City Gets
No Excavation
The liner goes in through the opening that is already there. No dig, no new structure, no rebuilding the street around it.
Back in Service the Same Day
A typical manhole is out of service for a single shift. Residents on that street are usually not aware the work happened.
It Goes in Wet
The system is installed in wet or dry conditions. In many cases a structure that is still taking groundwater can be lined without being dewatered and held first, depending on the conditions at the site.
Warranted in Writing
A twenty-year warranty on manholes, and ten years on lift stations and wet wells. The licensed installer warrants the installation.
A Pilot Program to Start
There is no minimum. Our pilot program prices a small selection of structures so a city can line the worst ones it owns, watch them, and decide about the rest afterwards.
Made Here
Manufactured in Northwest Florida for more than thirty-five years, and installed in cities across the United States, Canada and Australia.
How a City Usually Starts
Send Us the Structures You Are Worried About
One, or several. Start with the ones that keep coming back. A photograph and a depth is enough to begin.
We Tell You Whether It Is the Right Repair
Some structures should be replaced. We will say so.
Your Engineer Gets the Specification Package
Issued directly to the engineer of record so the work can be specified and bid properly.
A Licensed Crew Installs It
Installation is carried out by contractors trained and licensed on the system.
Questions Cities Ask
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.
What is warranted?
A twenty-year warranty on manholes, and ten years on lift stations and wet wells. Installation is warranted by the licensed installer.
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.
