BE-13 Renovation: Lining with Cured-In-Place Pipes - Processes - v01


Inserting the Preliner (PE Tube) / Slip Sheet

Before the lining tube is inserted, the preliner is blown or inverted into the sewer section to be renovated using pressurized air.

If no preliner is required, that means the lining tube is equipped with an external membrane, at least one protective foil (slip sheet) is drawn in to protect the lining tube from damage during the winched-in-place insertion.
