Need some tips and help to stop water sitting on the inner roof from condensation i'm guessing?
i have 3 x 1000 IBC tanks that are left filling over night however its so damp and wet that its dripping over everything, what the hell can i use or buy to stop all the excess water condensation build up as it is really doing my head in.
must be others that have had the same thing and if so what can i do to sort the problem?

thanks

Dehumidifier or some type of ventilation

Sounds like you've outgrown it to me.

industrial dehumidifier should do the trick http://www.ebay.co.uk/sch/i.html?_sacat=0&_nkw=industrial+dehumidifier&_frs=1

Collect the water and use for window cleaning.

I used to keep stock at a 40 foot container and you will get condensation without 3,000 litres of water. Also, there's no insulation. I imagine it's pretty wet in there. I'm no expert, but I wouldn't have thought one dehumidifier would do it. I assume lagging the roof is impractical?

As Don says, you need ventilation.

You could use a Flettner wind vent on one end of the roof, maybe even 2, and an inlet vent on the side lower down with cowling.

Then you need to ensure water spills are kept to a minimum and wiped up as soon as they happen. Wet clothes shouldn't be dried inside as that's added moisture into the air.

Buy a heater.

Rent it out as a sauna.

You need to insulate the inside of the roof with polystyrene or kingspan or similar. Stick it up with no more nails, silicone or gripfill.

Thanks, gonna get a dehumidifier and see how that works first. Really annoying me.

Cut a couple of square holes out and fit plastic vents.

You need insulation boards like Kingspan or Celotex 8x4's 100mm ideal. Industrial de-ioniser will shift 10 litres a night easily but won't solve the problem and not the cheapest solution long term. No more nails will hold the kingspan on virtually any flat clean surface, used it in my garage, still up ten years on.
