Foam-filled, membrane-covered barrier for raising flat roof low areas

摘要: A low cost method for constructing barriers to eliminate a flat or pitch roof's spots. Puddles, if allowed stand there, shorten the life and can do structural damage roof deck. Each barrier includes flexible membrane initially sized shaped then positioned cover at least one spot substantially overlap latter's edges. So positioned, is heat welded otherwise joined form continuous watertight seal, along its outer periphery, between an existing deck covering and, when next parapet, parapet as well. Filled with solidified plastic foam sandwiched covering(s), such barriers, once they have been mechanically fastened necessary, permanently direct storm water away from each of barrier-covered
