(PigletJohn and others????) Newly converted garage with recently laid Amtico wood effect vinyl flooring and no current signs of leaking radiator pipes or roof....So why has the new large rug I laid down on the floor become very very damp and the nonslip mat beneath it and the Amtico flooring beneath that?
I'd also laid the new curtains on top of the rug, prior to hanging them and they too are very very wet. There's been sufficient dampness to penetrate from below the nonslip mat, through the rug, to the curtains on top. I am extremely confused.
I've got two theories and wonder if anyone can help me resolve things? My first theory is that the synthetic vinyl flooring, covered with a nonslip mat of synthetic material and then a part-latex, synthetic material rug have all created some kind of condensation 'trap' between the layers. Is that possible if you lay synthetic, non breathable material on top of vinyl? (I'm assuming the nonslip mat and the part latex rug are 'non breathable').
Can you get a build up of condensation on a floor like this, if you cover it? The area of the rug that became wet is beneath a window but also beneath a radiator.
There's a condensation problem in the room as there's a build up of condensation between a circular single pane window and the secondary glazing which was put up over it. It's not too bad now (that was another post here) but is still occurring. Haven't been opening the windows because it's been cold and wet outside but maybe should be doing this?
Second theory - which is more worrying: the new en suite toilet off this room, leaked a while ago (posted about that here too) and the builders returned to fix the waste pipe and hopefully prevent further leaking. There hasn't been any visible signs of an ongoing leak from there but I was worried at the time that the leakage had penetrated underneath all the newly laid basic flooring (a 'floating floor') and would remain there and slowly penetrate upwards across time, once the Amtico floor had been laid.
The builders assured me that it would be fine and that the floating floor they'd laid had an antidamp liner, as per builder regulations - so there couldn't and wouldn't be a problem with residual damp rising through the floor. Are they right? Or could this be what's happening now? But can dampness penetrate to that degree upwards through the builders floating floor, the flooring companies initial boarding out on top of that and then the Amtico vinyl as the final layer?
Why would this damp problem only be happening in one area, if this were indeed the case - and that area being furthest away from the en suite toilet?
So from the info. here, has anyone got an idea about why my rug and floor became wet? I've taken up the rug and nonslip mat but does this mean I can't lie a rug on the floor at all or would I need to replace the new synthetic one with something natural like wool and would that stop the possible condensation issue (if that's what it is)? Is this a common problem with synthetic rugs on vinyl flooring or could it even be something about the nonslip mat beneath the rug that's causing the issue (rug and nonslip mat are both Dunelm Mill)?
