Prestressed Concrete Cylinder Pipe is frequently used in trenchless applications, owing to its design which incorporates a steel cylinder for watertightness and a concrete core circumferentially prestressed with steel wire. The idea behind PCCP is to combine the best of concrete and steel into one package, but the design does have its weak points. Corrosion caused by contact with soils containing high levels of acid, chloride and/or sulfate can lead to PCCPs failing prematurely. Since PCCPs are often used as water mains, their failure can seriously disrupt the communities in which they’re buried.
