What causes the laminate floor to bubble-up?

For the following reasons, your laminate floor may swell, bubble up, and buckling (in worst cases).

Moisture Problem

High-moisture or humidity level is the first & foremost reason behind bubbling up the laminate surface. If there are any leaky pipes under the floor or have a bad moisture barrier, the laminate can’t resist moisture. In return, it starts swelling over time.

Even small spills of water can cause this issue as the laminate base can’t withstand water. 


Delamination is another fact that may also be a reason to swell up the floor. If you can’t install the laminate planks correctly or damage occurs while installing, it will puff the laminate base.

There is no gap between each plank

The laminate plank will expand over time due to the temperature change. If the installer doesn’t leave any gap, the planks start lifting. In return, your laminate base begins to bubble up. Therefore, the floor will swell if you attach the molding tightly.

Lack or no expansion joints

Installing the laminate floor in a large area requires a gap between the joining section. Extra-large area installation may trap the air under the laminate planks, which will be a reason to swell up the surface.

On top of that, poo installation of the plank will be another fact behind bubbling up the laminate base. Don’t interfere with the venting system of the floor or install the moisture barrier poorly. Otherwise, the surface starts bubbling up over time.
