Televised ducts under slab floor. Ducts are concrete with metal fittings and connections that are very rusted. Plenum under furnace is also very rusted. Suggest spin cast mortaring metal fittings then spray lining ducts with Duct Armor duct lining material.
We are applying the second application of our rubberized duct lining material to all of the heavily rusted underground duct work.
We are applying our Trenchless Cast mortar to all of the heavily rusted connections and elbows in the underground air duct system. This mortar will give these areas a strong structure and dirt and debris will no longer enter from these points. We will then encapsulate the entire underground air duct system with our rubberized duct lining material.
Cleaned all the underground duct work with our hepa filter vacuum system and coated the moldy ducts with our duct lining material to eliminate the mold and future mold growth.
