You maybe will find that the PVC flooring will bulge during the use. And many times people will habitually think that the quality of the PVC flooring they choose is not good. However, in fact, this idea is actually incorrect. We will explain the reasons below for you.

If the moisture content of the base layer is too high before floor installation, and the base layer is not completely dry, floor paving will cause the moisture to continuously evaporate and form gaseous water vapor to accumulate upwards, forming elliptical bubbles. (You must know that PVC flooring is an impermeable material)

Before construction, the strength of the base layer is poor, and the ground is sanded. After the installation of PVC flooring, due to the movement of personnel or the rolling of objects, the glue is degummed, self leveling and slowly powdering, resulting in hollowing of the floor . (usually in the form of elongated bulges).

The short drying time of the adhesive after construction resulted in the formation of dense semicircular small bubbles on the floor. After the installation of PVC flooring on the ground floor or basement, the original base layer did not have a moisture-proof layer, resulting in the rise of moisture and the formation of large bubbles. The old base layer has oil stains permeating the ground, and the adhesive fails due to the reverse infiltration of oil stains at the bottom layer, resulting in hollowing.

Improper installation methods during installation can cause the floor to bulge if it is not fully adhered to the ground or if the ground flooring to bulge due to shrinkage or expansion. Especially in extreme temperature environments, this situation is more common.

When using PVC flooring in a humid environment, water may accumulate below the floor, causing the underlying material to expand and bulge. Some PVC flooring may have quality issues, such as uneven underlying materials or weak adhesive, which can lead to floor swelling.
