This air duct lining case study highlights a unique problem faced by a Park District in Illinois. Because of the nature of the problem and the urgency involved, Trenchless Innovations quickly devised a customized air duct lining solution to the problem that resulted in long-lasting, brand-new pipes in place of the old, severely deteriorated ones. 
The Problem:
When replacing an older furnace, the Lombard Illinois Park District discovered that the 36” galvanized steel cold air return beneath it was severely deteriorated. Hoping that a simple cleaning would remedy the problem, they hired a cleaning crew to clean the pipe. This hope was dashed when it was confirmed that the bottom of the pipe was so badly deteriorated, there was no structure left to it.
Our Solution: Trenchless Casting & Air Duct Lining
Trenchless Innovations was contracted to perform air duct lining to restore the piping so that the new furnace could be installed. Since the old furnace had already been removed, time was of the essence and the Park District needed a quick but effective solution to their problem.
We began with a thorough visual assessment of the deteriorated piping and determined that because the deterioration was so severe, trenchless casting was necessary to first restore the structure of the pipe before the air duct lining could take place.
On the day of the job, Trenchless Innovations pumped mortar into the bottom of the pipe and mortared through the entire 36” pipe. Our trenchless casting process restored the structure of the old pipe by creating a new one within it. After trenchless casting, one coating of our proprietary Duct Armor material was applied to further strengthen the pipe and restore it to like-new condition.
Air Duct Lining from Trenchless Innovations Gets Results
The result was completely restored, newly lined piping and a relieved and happy park district superintendent whose unexpected problem was solved quickly with a long-lasting solution. Bill Sosnowski, Superintendent of the Lombard Park District, says “Trenchless Innovations responded to our situation within two days, set up a repair for the following week and completed the project on time, as they knew we were in a bind to get the replacement furnaces in place. They were professional the entire time, explained what needed to be done and completed it as scheduled. They protected the area surrounding the repair and cleaned up after all work was completed. Mixing concrete and spraying sealant could be a mess but there was never one made. I highly recommend Trenchless Innovations.”
