    hi folks, i have an average 1930's 3 bed semi built into the side of a moderate incline.
    i have recently dug down under the staircase to open up the cellars -one under the lounge, one the kitchen- to find i have damp walls along the front of the house and down the gable end. The gable end tho not 'dripping' wet, seems to retain some damp throughout the year.
    in order to make these rooms dry and useable, could i just paint all the walls with a liquid damp proof membrain , then stud with s/s battens and insulated plasterboard ?
    or am i being too simplistic ?
    cheers in adv for any advice

    Some things for you to think about;
    1. where is the damp coming from? It could be from the floor, from the walls or from flood!
    2. is there any ventilation? you will need good ventilation in (what I assume is)a large area to make sure any moisture in the air doesnt condense of cold surfaces. If there is no ventilation any moisture from the floor will be taken up into the air and will condense on the cold walls.

    If you are directly on earth or quarry tiles on ash considor taking up the existing floor and laying a DPM and screeding. This will block any moisture coming up from the floor and may help the problem.

    Get a local builder in to quote you and use his knowledge.

    ok, ya caught me bang to rights, lol
    i also posted it in the plumbers forum too .
    yes Loo , both rooms are approx 6x4 mtr with 8' ceilings, there is more than adequate ventilation - much to my annoyance - (draughty as hell through the floorboards). in the other forum it was suggested i use "synthaprufe" which seems ok but it looks rather expensive for the area i would need cover. Again , in there i asked about a wall within a wall, awaiting response.
    the damp i do believe is purely run off rain water courseing its way along the walls on its way down towards a lower garden.

    Have you considered a french drain to channel the run off away from your walls? I'm not saying this is a complete answer just an option.
