Lining underground air ducts with Duct Armor. Renewing and sealing the air duct system.
We are cleaning all of the heavily rusted underground air ducts in preparation for our Trenchless cast mortar. We are going to apply our Trenchless cast mortar to all of the underground air ducts to give them a strong concrete structure. This will keep dirt and debris from flowing out of the air vents and throughout the home. We are then going to apply two applications of our rubberized duct lining material to completely seal the air ducts.
Televised ducts under slab floor in basement area. Ducts are PVC with metal coupling and fittings. Customer is getting slightly elevated radon gas levels. Radon company suggested sealing ducts prior to installing a radon system. Suggest spray lining the ducts with Duct Armor duct lining material.
