Maintenance of sewer pipe process sewer pipe repairing process is necessary for deterioration of sewer pipe. In this
research, analysis on performance (strength and twist strain) of eco-friendly and even expanded liner process using
glass fiber and twist prevention band. As a results, tensile strength, bending strength and failure load is increased after
the sewer pipe repairing process than advanced research results. And sewer pipe after the this process obtained
advantage of prevention of twist strain and economic. After the this research, sewer pipe repairing process using glass
fiber and twist prevention band could be suggest the eco-friendly and effective sewer pipe repairing process.
