Abstract
Manholes and other underground structures commonly account for 25-30 % of infiltration and up to 70% of inflow in sanitary sewer collection systems. These will cause sewer overflow and endanger the nearby environment. SprayWall is a spray-applied, cured-in-place method of construction and is primarily used in manholes. It uses urethane material that provides excellent corrosion resistance. SprayWall is structural and can withstand ground water loads on a long-term basis.
