Sliplining is a technique for repairing leaks or restoring structural stability to an existing pipeline.
[1] Sliplining can be used to stop infiltration and restore structural integrity to an existing pipe.
It is also very easy to install and requires tools and equipment widely available to any pipeline contractor.
[clarification needed] Installation usually requires excavation at the insertion and receiving pits.
Some pipeline owners may prefer to leave the bead in place as it often does not affect the installation.
