Method for renewal of pressure no-go water conduits. One makes flexible spiral steel-fiber armature-frame, where the long glass fiber armature is used as stopper of the pitch of working spiral armature and the circular templates û slides are installed in number providing same separation of the armature-frame from the inner surface of the pipeline being renewed. One pushes the armature frame to the pipeline being renewed, with flexible polyethylene sleeve with anchoring outer surface placed in it. One fills the polyethylene sleeve with water, with formation of hydro-tightening weight casing where the sleeve is non-removable falsework û lining. One pumps cement mortar to the inter-pipe gap with pressing it in radial direction through increasing pressure in hydro-tightening weight casing.
