At Daily Drains we will inspect your pipes with our high tech CCTV equipment this will reveal the extent of the damage. The CCTV camera gives an exact meterage from the point of inspection of where the damaged pipe is, also the camera is equipped with a sonde which emits a signal that our CAT scanners can detect and pin point the exact location. Excavating is a last resort as most repairs can be carried out without the need to dig but it is necessary in some cases.
The excavation process can sometimes be quite lengthy as factors have to be considered such as how deep is the pipe from the surface, is it soft ground or hard ground that needs to be dug up and is there anything obstructing the dig such as a garage etc.
However once all the factors have been considered a trench would be dug up exposing the pipes, to do this it will either be by a mini digger or manually. The pipe will then be repaired and the trench back-filled and left in exactly the same way we found it pre excavation – so if you have turf on top then this would be relaid.
When is a drain excavation necessary?
Excavations are necessary when:
- A pipe has collapsed
- Deformation of the pipe is more than 30% of it’s original size
- A no dig repair will not suffice
- The pipe is old and in need of being replaced
