Bouncy Laminate Flooring
We have a problem in a house our preacher lives in. Lowe's installed some laminate flooring and for some reason there is a hump in on spot that is springy when you step on it. We took the flooring up and we didn't find anything under the flooring or any reason it would be humped and springy in just one small spot.

My question is this, is there a type of glue I could glue that one spot down? There is plenty of clearance for the floor to move so that isn't the problem. I was thinking maybe use a butyl caulk to glue that spot down as the butyl caulk doesn't completely harden and would move if the flooring expanded or contracted. Will this work or what should I use?

Look over the tongues and droves for any damage.
One trick I use when installing laminite is to never just try and force it down in one motion. I sort of work it up and down going lower each time. It works the T & G into the grove.
Once I have tapped the butt joints together I tap over the whole surface with a dead blow hammer gently. I've seen the tiny gaps close up from doing this one thing, and it stops the floor from trying to pop back up.

sure the planks were not bowed ? i had that problem with engineered i did in my old place. the directions said it was ok to use slightly bowed boards = don't believe that.

I wouldn't suggest any glue for laminate, if the planks have peeked or popped up then it should be replaced so it doesn't happen again because if the T&G is damaged its going to expand in that area before it uses the perimeter to expand.
Also double check all walls for expansion gaps.

I took that area up today and there was a hump in the underlayment, sanded that area down so it is dead flat now. I will reinstall new flooring tomorrow and see if that takes care of it. Thanks a bunch for all your help, I do appreciate it.
