floating wood floor trouble
I am having trouble with a floating laminate wood floor. It is adhered to a sticky-back foam, which rests on a vapor barrier on top of the old carpet. Plenty of room was left around the perimeter for expansion, and I think now too much was allowed. This is in a rather large meeting room (40X 40'?) which has several door ways, connects to a hall and also another room. The entire floor has shifted to one end, and is apparent at all these connections. How do I move it back? Should I? What about all the entries? Gaps?
Carpet may be the problem
At my workplace we had a rubber mat laid over the carpet at the entrance for protection from wet feet. The mat was laid loose over the carpet. As it was walked over it would move slightly, after a few weeks it would move sufficiently to create a trip hazard. However it always moved in the one direction on all occasions. I suspect that the individual fibres in carpet tend to slope slightly in the same direction. As part of the manufacture they are uniformly bent in the same direction, ie not random. Any foot pressure on the mat (or the floating flooring) would slightly depress the fibers further and when the foot pressure was released the fibres would attempt to stand upright. Each individual fibre would be "brushing the bottom" of the mat and creating a small force that eventually moved the mat in the same direction.
This minute but often repeated force would have the effect of brushing the mat (floating flooring) in the same direction every time, gradually moving it ALWAYS IN THE SAME DIRECTION.
Still with me?
To test this hypothesis. Get a small piece of your floating flooring or three ply and place it on top of any other carpet in your place. Stand on it, lift foot, repeat, repeat, etc.
Does it always move in the same direction?
I have no experience with floating flooring, nor can I suggest a solution to your problem: but I suspect the carpet may be a continuing problem.
