Duct Armor HVAC Liner for Air Duct Repair

Trenchless Innovations is proud to use Duct Armor, a proprietary water-based latex material, in our duct lining process. Duct Armor contains zinc to prevent the growth of mold and other bacteria and is safe for all occupants as it contains no harmful chemicals. In fact, you do not have to leave your home during application, and you can turn your system back on as soon as we finish the lining process!

Duct Armor is completely rust resistant, and because it is made up of 50% bonding agent, it provides excellent adherence to your existing ducts and onto itself. It will not be damaged by water, however, water problems in your ducts should be corrected before lining your ducts.

Our underground air duct lining technology eliminates costly repair bills by restoring your deteriorated underground ductwork without the need for digging and it provides many long-lasting benefits:

  • Lining your ducts completely restores your old, deteriorated underground ducts to a better-than-new condition

  • Our process is quick and non-invasive and it eliminates the restoration work commonly found after complete system replacement using traditional air duct repair methods

Trenchless Casting

It has been our experience that in some cases, the condition of underground air ducts are so severely deteriorated that there is no longer any structure left to them.

In these cases, Trenchless Casting serves as a way to restore structural integrity back into the ducts so they can then be spray lined with Duct Armor.

Your air duct repair could be easy and effective with our duct lining solutions.

Trenchless Casting is most commonly used to restore the structural integrity of galvanized and cardboard (sonotube) ducts that have deteriorated due to rust or elements over time. Although not used with every restoration project, it provides additional strength to our lining process for pipes in pretty serious disrepair.

What are the benefits of Trenchless Casting? There are several:

  • Our process gives you brand new pipe within your old pipe, making them suitable for duct lining.

  • Trenchless Innovations provides a 15 year warranty on the process, but we know it will last much longer!
  • Used in conjunction with duct lining, the trenchless casting provides an agent for our Duct Armor product to better bond to. A great combination that results in new, strong and long-lasting pipes for years to come – and no worries for you!
