We are applying the first application of our rubberized duct lining material to all of the underground asbestos transite air ducts.
Televised ducts under slab floor. Ducts are concrete possibly Transite with asbestos with metal fittings and connections. Metal fittings are very rusted and deteriorated. Suggest spin cast mortaring metal fittings then spray lining ducts with Duct Armor duct lining material to encapsulate the concrete ducts.
