The method involves applying a swellable sealing unit (3) on an inner wall (12) of a sewage line (10) which is to be reconstructed, before introducing a liner (2) in the inner wall. The sealing unit swells after the introduction and positioning of the liner and seals an annular space between the inner wall and the liner through a closed circumferential line. A passage opening is applied in the liner at a nozzle of a branch line after the introduction and position of the liner and swell of the sealing unit. Independent claims are also included for the following: (1) a sealing unit for reconstruction of a sewage line guiding fluid (2) an arrangement for reconstruction of a sewage line guiding fluid.
