Patch liner repairs are a process that involves using CCTV to identify cracks and holes within drainage pipes without needing to dig
Patching a sewer is similar to relining, however it is done for smaller damaged lengths of liner in a specific section of the sewer or drain rather than lining the whole pipe.
First, a fibre cloth tube is placed inside the sewer around an inflated 'packer.'
While the glue cures, the packer expands and presses the patch against the sewer wall of the host pipe (generally an ambient cure). The packer is deflated and extracted from the host pipe after curing.
CCTV is used to check the patch, and any lateral connections are re-opened using robotic cutters like to what is used for full-length liners.
