    Hi, hope you can advise... i purchase my c1900 flat and during bathroom renovation i discovered low down damp which i presume if rising damp. I'm looking at DPC'ing this with DryZone, any good?

    Also from the pics, i've taken the plaster off down to the red bricks, they are quite brittle so is there a way of fixing that or will using DPC eventually dry them out? once dried out how would i treat / seal them?

    I've attached some pics, many thanks...

    Bath was probably leaking, not rising damp, will dry out, check external pipes/gutters have no leaks as another possible source.Make sure your new loo overflow cannot run down the external wall.

    I'l look into doing this myself using dryzone, looks like a good product.... or how much would it cost to be done professionally do you think?

    Stabilising solution might help with the bricks but ~I'm not sure how that'll work with the damp proofing treatment...you'd definitely have to use the stabilising solution first as it needs to soak in which wouldn't happen after a DP treatment.

    Ok, might get a pro round and have a look, whats the general process for treating damp? DPC first, then stabilising solutions, then? many thanks.

    Hi again.... got a pro in and he listed the below, so i'm going to give it a go myself.. Any preferred supplier of the Salt Neutraliser / anti-sulphate? ideally i can drive somewhere to pick it up, seems online delivery most places... thanks....

    Bathroom
    1) To apply anti-sulphate onto the brickwork.
    2) To plaster the wall with sand and cement with SBR additive.
    3) To apply 2 coats of tanking slurry with a 150mm lap on to the floor slab.
    4) To dry line the wall with plasterboard. (ready for tiling which is not included in
    this estimate).
