I have had cushion flooring fitted in my kitchen/dinning room for about 18mths and it has started to bubble and crease up, so we lifted th floor up and the floor is damp we have checked all near by water source but no leeks. There are no water source with in 2m can not figure it out. Does cushion flooring sweat :confused: floor fitter said no point in glueing floor because we need to find out where damp is coming from

Is it a cushioned vinyl ? What part of the world are you in ? US, UK ?

Ok here we go the reason I was asking about it being vinyl is that there are different types of products in different parts of the world. As far as the wetness goes either you have an external leak like a supply valve,drain line etc. or you have a pipe inside your concrete floor that is leaking or the concrete screed you used to level out your floor wasn't completely dry when floor was installed or you have natural moisture from outside wicking up through your concrete. Climate could have an effect on this ? Post back and tell us what you think. GOOD LUCK, AC

I see this a concrete moisture problem wicking into the concrete. We do a preliminary cheap test for moisture in a concrete floor. Cut a piece of 6 mil plastic 24"x24". Lay it on the floor and duct tape the edges. If there is any water droplets in 24 hrs then there is 5% of moisture in it. Not Good the more accurate test is this and is in your neck of the woods before the U.S.

Good job boat that's the same problem I suspect can't figure why it didn't show up with the previous flooring though. AC

Like people all floorings are not the same. Add to that the different environments they all get put in. More so then not it the location/installation problems.

Take for instance Armstrong's designer inter-flex solarium's. "floor with a Memory" Glue side 4" seams 6" pull tape off sheet good install. Shrinks over night and tightens. BUT the Armstrong's glue to glue it down is a number/letter off for a below grade installation. It's the fine print
