Hi all, a recent CCTV survey has shown 5-6 areas of large joint displacement along an area of drain 5 meters in length. One company has said to do individual patch repairs. The other has said to reline that whole section. The 5 meter area also includes a 90 degrees bend around a corner of the property, again I got different views with one company saying that they will need to excavate the gully to access that side and the other saying that they can go around it using the manhole.
Are there any views on how to decide the best way to rectify the issue? Is there an advantage of the patch repair vs the whole pipe lining given that the latter seems to work out cheaper?
All the displacements are between RWG3 and RWG2 shown in the photo below.
