Renovation Slip Lining

Slip lining with an inserted pipe used for “renovation” purposes may utilize the same techniques as in “replacement slip lining” (where the methods are described more fully). The distinctions between the renovation and replacement categories depend on the extent to which the liner will function as a fully independent liner after installation as discussed in the descriptions for the “replacement” and “renovation” categories.

Also, included in the renovation slip lining category are techniques involving inserting a flexible hose to provide the pipe lining or to fulfill the operational function of the existing pipe to carry an internal flow. Such inserted hose linings may or may not be considered close-fit depending on the technique. Hose lining techniques only fall under the renovation method category since they do not attempt to replace all the structural and operational functions of the existing pipe.
