    We've the below footpath which has seen better days. We wanted to replace it with paving but budget won't allow so for now we were thinking of just tidying it up.

    I was going to put a new edge of treated timber and then just pour new concrete over the top but is this even feasible? The pictures show the worst of path and the rest is pretty much OK.

    What other prep is needed? We only need it to last a year or so and then we'll sort it properly.

    You'd want to dig a good trench at least a foot wide and deep to make room for your timber. Make sure all existing moss/growth is treated. Powerwash after treatment. You will need to put down some steel to prevent cement cracking. Make sure you get the right concrete mix - fine aggregate. Also make sure you follow the slope away from the house (run horizontal timbers to get correct fall)

    Also keep the new path surface below the damp proof course.

    Let us know how you get on, I want to do somthing similer but just make mine wider.
    They are in good shape but sinking a bit (or sank sometime in the last 50 years).

    I'd rent a consaw and cut back the broken inches remove it entirely and put soil in there.

    Cheaper and less work than pouring entire new path.

    I'd see no need to keep it as wide as it is.

    If you are going to redo it in a year or then either do as lister suggested or just leave it, its a lot of, IMO, unnecessary grunt work

    the problem is we've had a few falls & twisted ankles already with the damage that's there, plus the width is needed to be able to walk past the bins etc.

    well then cut off the offending piece, dig a 400 mm deep trench out to the full width you want the path and fill it with 804, which can be used as base fo the paving when it comes.

    Move the bins. Genuinely put them somewhere else they are best of where they are between their final destination and door back door. They appear to be in the backyard in an area where dragging them out and back just creates unneeded hastle

    What is the width of existing path ? Typical domestic paths around a house are 900mm or 1 metre.
    I certainly wouldn't be placing concrete on top of what's there at this stage.
    As already suggested, get someone handy with a consaw to cut a straight line and remove the areas that have failed.
    If remainder is fairly stable and good nick you could just concrete a strip to replace the removed portion or just gravel / topsoil for now.
    There should be a damp course in the house walls at floor level.
    Outside path level should be min 150mm below damp course level save for steps and ramps.

    Rear path is 1.5m and the sides/front are 1.2m and the bins are staying put (they only go out once a fortnight and we putting stuff in every few days so having them away from the kitchen/back door makes no sense to me).

    Anyway thanks for all the replies, I've a few options to investigate for now.

    Would this be possible over a tarmac drive.I've 600m2 which is getting holes in it and a build up of moss and weeds. Could I pour concrete over it.?

    Can you not just seal it?

    Not my specialty, but I expect pouring concrete over tarmac is a recipe for heartache. Tarmac is considerably more flexible than concrete, so even if you're not driving vehicles on it, the movement of the tarmac as temperatures go up and down will cause the concrete to crack. Then you you need to dig everything up and start again.
