i have just been asked to go out and check out an vinyl installation where the previous layer laid over the top of parquetry.
it has been down for about a year, and recently in the last couple of weeks or months <im not sure which> the parquetry floor has began to buckle and pop off the floor.
with my limited knowlege of timbre flooring products and not actully seeing the floor im suspecting possiblly a pipe has split inside the slab or some other form of moister.
is there any other possibilities?

No, someone place a material with a high perm rating, over the wood, trapping all the moisture. If this is over concrete, it was just a matter of time. If it is over pier & beam, you have trapped the crawl space moisture.

You cannot place a moisture barrier over wood making a wood sandwich with moisture barrier bread.

Zackly right.

Just had such an issue in a candy store at a mall. The installer put karndean over parquet wood tile - over a slab -and it buckled like you wouldn't believe.

Got big bucks to rip up the jellybean Karndean, scrape the parquet off it and re install after putting a moisture retarder down.

One of those cases where a hack actually helped me make money

Good answer! Not to mention the vinyl installer used latex adhesive. They should have just pulled up the parquet or refinished it.

Moisture trapped. compromising the parquet. I just follow FloorDude around the board and second his responses.
