Check the humidity level of the room and use a dehumidifier if the air is too moist particularly depending on the time of the year.
Floor is bowing up.
During installation run a vapor barrier under the vinyl plank flooring to help prevent buckling from moisture.
If water seeps up under the flooring from an extremely moist concrete subfloor the adhesive can be weakened causing buckling in the floors.
Bowing or warping of floor boards can occur for several reasons.
First off you need to identify the areas where the floor is bowing to figure out where the floor is butting against the perimeter.
The higher quality the material the less likely it is to buckle due to moisture.
Because soil shifts and house frames settle there is usually a slight variation in floor level.
Another important part of installation is the expansion gap.
If water has seeped into the boards they may swell against one another which can cause the bow.
How to fix bowed floors.

Without this barrier moisture can cause buckling.
A moisture barrier is a thin sheet of polyethylene that is laid between the subfloor and the hardwood.
