Pipe material tells you what the system is made from; CCTV shows the visible condition inside it. A repair assessment also needs the affected length, connections and available access.
These references are used across the library for the products, systems and technical points they cover. Manufacturer information applies to the named product or system; whether a repair is suitable still depends on the installed pipe, its condition and how the drain is used.

Reported pipe defects
A crack in a drain wall needs to be assessed by its extent, position and host-pipe material. Pipe material alone does not determine the repair.
Reported pipe defects
Leakage at a branch or junction may need a local repair. The junction geometry and the condition of the adjoining pipework are part of that assessment.
Reported pipe defects
For an open or gapped joint, the repair depends on the size and position of the gap and the condition of the pipe on either side.
Reported pipe defects
Root intrusion can obstruct a drain, but clearing the roots and repairing the entry point are separate issues. The surrounding pipe still needs to be assessed.
