We're currently having a single storey downstairs extension, the builders have been today and completed the brick and blockwork up to about 1m height. After they left it rained for at least an hour (while I was at work but DP was here). When I got home the insulation between the two was really wet to touch. I've covered it now and had a real moan at DP for not doing it.
Just wondered if anyone knew how much of a problem this is? Does it need to be pulled out and replaced? Not looking like there will be any sun anytime soon to dry it out.
