CIPP Patch Repair
CIPP Patch Repair utilises materials similar to those used for full manhole-to-manhole CIPP lining but in short lengths. Installation usually utilises an inflatable packer around which a resin impregnated liner is placed.
The packer/liner combination is winched or pushed into correct position over the defect with the aid of a CCTV camera. The packer is inflated and the liner is allowed to cure, usually under ambient cure conditions.
Once the liner has cured the packer is deflated and removed leaving the patch repair in place.
