ABSTRACT:
A method and apparatus for guiding an everting form employed to carry formed-in-situ repair material into a pipe or conduit comprising passing a guiding means through the interior and along the full length of the everting form in its un-everted state; fixing a first end of the guiding means to a substantially closed end of the everting form; attaching the guiding means in a readily detachable way to the interior surfaces of the everting form and the repair material substantially throughout the length of the everting form; and, during eversion of the everting form, applying tension to the guiding means to assist in guiding the transition of the zone of eversion through directional changes and discontinuities in the pipe or conduit and prevent localised axial differential movement between the everting form and the repair material immediately upstream of the zone of eversion.
