A bituminous coating is a type of coating used to build a vapor-proof and flexible protective coat in accordance with its formulation and polymerization grade. A bituminous coating's flexibility and protection against vapor and water can be influenced by the polymer grade as well as reinforcement of fiber. The most common applications of a bituminous coating include areas that are beneath screed wet. It is an excellent protective coating and waterproofing agent, especially on surfaces such as concrete foundations. A bituminous coating is regarded as one of the least expensive ways to provide cathodic protection to pipes. It is also the least complex coating process, making it suitable for casing pipes like in road bore.
