    Sure thing. I’ll get those over for viewing tomorrow.

    No it’s not going through a wall. Hopefully new pictures will make it clearer.

    That's all i could do today. As i am digging the clay/mud is very wet indeed. I'll need to take out the makita and chisel that nasty concrete that's in casing the pipe. I put the water on to see if any leaks were showing, but none as yet so I'll continue tomorrow. Hopefully it'll be cooler!

    I wouldn't worry about breaking any more of that concrete away, if you've a solid section of pipe there you've already exposed, cut through it there, (leaving enough to get a coupling onto!), then just break the rest of the old stuff and pot out, (making sure you dont damage the section you need to leave in situ!) Once you've got all that out, offer the new gulley in, and connect up. I would suggest some lean mix concrete under and around the base of the gulley to support and hold it in position, then bed pipe in peagravel, before backfilling. Try and avoid big lumps or stones in the initial backfill if possible.

    Benching in the chamber also looks in poor condition, ideally wants redoing, although as a shared sewer, it is the Water Company's responsibility, may be worth asking them first if they wish to look at it/carry out remedial works.

    You've done well with the concrete over the pipe = looks like you've got enough pipe exposed now to cut it with an angle grinder and diamond disc thus leaving a stub from the manhole - then you can break and wrench the gulley and other bit of pipe out with no strain on the pipe you want to keep.

    Thanks. Digging in this heat is very difficult.
    I'm going to leave it for a few days so it can dry as much as it can in the heat. The thing is - it's so wet it's gonna take months (that correct) to dry? And if so, what an earth will I need to do with the kitchen painting issue etc, i can't leave it unfinished for months :(
    Also, maybe i'm a little worried but I dug a little further around the man hole as it's all wet - am i correct to think that this was due to the leak top end flowing and spreading all over that area?

    Below the current status. Cheers all.

    You have done very well for a spark, they normally don't like hard work or getting their hands dirty! :ROFLMAO::ROFLMAO::ROFLMAO:

    Could put the new gulley in, set it etc. and connect up, leaving the excavation open for now to dry out a bit, then gravel up and backfill at a later date. I'd want to get that downpipe connected to the drain somehow at a minimum, if we get these storm the Met Office are forecasting, your excavation wont be drying out anytime soon....

    Notice there is a waste pipe coming out under the wall, is that still in use? I'd also be looking at that lead service, these can be notorious for leaking given their age, especially if there's no sign of any noticeable drying out, given the current temperatures, (if you're in the right part of the country...)

    Get a bit of spare gutter and have it ready to span that gap if it downpours, that could be imminent depending on where you are, at least to direct most of the downpipe water into the clay, until the gulley's in.

    As above contact the utility ref the common drainage. see if they will consider individual drainage (and water services maybe)?
    The manhole chamber is shot and the benching is cracked and maybe leaking at the inlets, the main invert channel might also be leaking - you have an inlet coming into the invert channel, where's that coming from, from under the neighbour's or a distant neighbour's?
    The manhole could do with locating about 10ft to the right.

    Remove everything from the inside corner (including the Pvc waste pipe gutter arrangement) down to soil.
    Hack off the plinth and any render on your wall.
    There's an air brick is the kit floor suspended?
    The neighbour's rendered wall abutment might be contributing to damp inside your kitchen?
