could you have used way too much glue, thereby introducing a ton of
moisture to the wood? If it happened overnight, sounds like the most
likely culprit.

also, did you acclimate the wood to your house before laying it?

Here's the situation - I laid 32 sq. ft. of 12" x 12" parquet flooring tiles
this weekend. Mfgr's instruction stated it needed to be glued (I used the
appropriate glue and trowel). It also stated to leave a 1/4" gap around the
walls which I did for expansion. Don't understand how it would expand if it
was glued down - but I did it anyway. I laid this same floor in my master
bedroom 4 weeks ago and no problems. It is tongue and grooved on all sides.
I woke up this morning and have a ridge down the middle of the floor which
buckled and raised almost an inch. I'm thinking the wood expanded alright
. . . now how to deal with it. My first thought since I can stand on it and
it lays down okay was to make an attempt to inject glue into the bottom
somehow and weight it down. However, if it really is expansion, it will
happen again somewhere else. What do you think? Take my circular saw set
at a very low depth and make a relief and then glue back down? Need some
suggestions from my experienced wreckers.
