Our team at P24 Pipe Relining Sydney successfully sealed multiple stack lines in a block of units by addressing all cracks and breaks in the 100mm clay pipe that served the entire sewer system. Through multiple inversions and junction repairs, we were able to restore the system's functionality and also created excavating points on the sewer line to facilitate future access for point-to-point relining. In addition, we replaced the old cast iron pipes with new PVC lines and inspection openings for optimal performance.
