PE-SL (Slip Lining) Method

• ∙ A method that inserts a new pipe with an outer diameter smaller than the inner diameter of the existing pipe;
  the new pipe is inserted by pulling a towing rod pre-connected to the new pipe into the interior of the aged water supply pipe, providing structural reinforcement.
• ∙ The void space between the existing pipe and the new pipe is filled with grouting to enhance resistance to bending that may act on the new pipe.
