摘要： A repair material and a repairing method, in which partial repair for faulty portions of a pipeline such as a sewerage pipe is surely effected in fewer working processes and in a short time. A repair material (1) is used which is composed of at least two layered cylinders with an elastic inner layer (2) held in an outer layer (3) in contracted condition. The repair material is introduced into a pipeline to be taken to a location where the pipeline should be repaired, and the outer layer is removed to cause spontaneous diametrical expansion of the inner layer for close adherence to an inner surface of the pipeline. In the case where the pipeline is small in diameter, the outer layer (3) is removed outside the pipeline and only the elastic inner layer (2) is introduced into the pipeline to be conveyed to a location where the pipeline should be repaired. Before the outer layer (3) is removed outside the pipeline the repair material is cooled to temporarily delay a diametrically enlarging speed of the inner layer. Conveyed to a location where the pipeline should be repaired, the inner layer is heated.
