In Bloomingdale, IL, I completed the initial application of RS-100 to all underground ductwork. RS-100 is a specialized coating designed to provide corrosion protection and enhance the longevity of duct systems. The process involved thorough surface preparation, followed by the uniform application of the RS-100 coating. This proactive measure ensures the durability and efficiency of the underground ductwork, safeguarding it against environmental factors for years to come.
