    Folks, my brother has a house with a rather damp cellar and wants to store some scuba diving kit down there. The dampness appears to be natural , although it does make boxes etc damp to the touch! He is clearly concerned about having expensive equipment in such an environment and is thinking about using a de-humidifier. If he uses a commercial type one, I suspect that it will suck a fair bit of vapour out of the walls, and am concerned that it may some how affect the foundations of his property and the two adjoining ones. The celler never floods but as it is on a hill, is not anywhere near a water course either. Do any of you think there would be any potential risks by using a de-humidifier? Thabks for your help.

    He's worried about getting scuba equipment damp ?

    Yorkshire, fair point!!! He is concerned with mould etc getting into breathing aparatus which would not be ideal. Also with diving suit and boyancy jacket, these might be affected unnecessarily. Reinforced rubber hoses can perish under damp conditions and as some of these are carrying air at 230bar (3400psi) this would not be perfect either. Just felt i needed to clear that one up!

    if you use a dehumidifier in a damp cellar all you will be doing is bringing more damp in from outside, if you want to contain the damp then you need to tank the room from all water ingress.

    I don't think coating the scuba gear in pva will make any difference

    Tanking is the only solution. A dehumidifier will not work in a room that has a <u>constant source</u> of dampness. Dehumidifiers work in rooms that have a <u>limited amount</u> of moisture in them that needs removing (newly plastered house, flood damaged property etc).

    Tanking cellars is a specialist job (if you want it done properly) and is not cheap.

    Just keep the scuba gear in the loft.

    Thanks for the advice guys, makes complete sense. Tanking would be too expensive and inconvenient to do, just to enable storage of equipment. He'll have to come up with another plan me thinks......

    What about waterproof, airtight containers kept in the cellar? There are lots of gigantic plastic type containers suitable (do a google search). You'd have to be pretty sure the scube gear was completely dry before putting it away though.

    Perhaps keep it in the boiler room for 24 hours prior to storage?

    What is the floor in the cellar?
    Is is on old quarry tiles? If so chances are that these are just laid on ash which is directly on top of earth.
    If this is the case chances are that the damp is natural and coming up from below. Add to this that you may not have any ventilation in the cellar this will make the problem worse. I had exactly the same problem in my cellar. Its fairly easy to sort out in a day with help from a mate!
    Tanking is all good and proper but if your cellar is generally dry there should be no need for it for what you want to use the cellar for. If your walls are dry there is no need to tank them.
    I had a dehumidifer in the cellar extracting over 5litres of water a day! and it didnt make a great deal of difference.
    Take up the quarry tiles (keep these to sell on as you can get good money for them), put down a plastic DPM on the floor and return this part way up the walls, concrete the floor. When dry you will be left with no water penetrating up from the floor and a dry cellar area.
    Include a supply and extract ventilation fan also. This will move the air and stop it from gathering water vapour and condensing.
    I now have no need for my dehumidifer so if you know anyone who want one let me know!!!
    All this will cost is the price of the materials plus the price to hire a cement mixer. After selling quarry tiles you should have enough left over for a couple of pints!!! :)

    Bcountry, Spoken to the lad and thinks that it may just be compacted earth! I don't suppose he will be too interested in doing any work after everyones advice as he has started looking (tentatively) at moving house. He needs a garage apparently, shame its not for a motorbike though! Cheers guys for all the advice.

    If its just compacted earth the DPM(blue plastic sheet) and concrete should sort out the majority of his damp problems. May be better off doing this before he sells up anyway. If its that damp it will come up on the survey.
    Here is the link to the photos of my cellar:

    I had a look at your pics - good job.

    Can you tell me how you put the wood on the stone stairs? What is that silver strip thing called? How did you fix the wood onto the stone?

    A brief summary of the process will be greatly appreciated.. Thanks
