I have a deep manhole which is suffering wear and tear. There are 2 large concrete rings above the drain which are pretty much OK except for 1 small chip. Above this are 2 narrower concrete rings, I think they may be called are called do'nuts. Both are cracked badly. I have had the cracks sealed as far as possible but there is still one crack which is too awkward to reach. Soil has been leaching into the drain from the drive and the tarmac is quite buckled although the drain runs freely. I no longer drive over the cover so can't use the carport. Is there anything I can do? Is it really serious? I have been unable to find anyone willing to carry out a repair. Any advice much appreciated.
