How water-resistant is a PVC floor really?

Hoe waterbestendig is een PVC vloer echt?

PVC floors are popular — and for good reason. They are stylish, durable, and resistant to water. But how waterproof are they really? And what happens if water gets under the floor, for example in a leak?

In this article, we explain it clearly, without complicated jargon.

Is a PVC floor water-resistant?

Yes — a PVC floor itself can handle water very well.

A spilled glass, a wet dog coming inside, or water in the kitchen is usually no problem. The material itself does not absorb moisture.

But with larger amounts of water, such as a leak or flood, damage can occur. Not to the PVC itself, but to what is underneath the floor.

The subfloor or glue layer can come loose, causing parts of the floor to lift or "float." That’s why it’s important to act quickly in case of water damage.

 

 

How can water damage to a PVC floor occur?

1. Water under the floor

In case of a leak, moisture can get under the PVC floor. This can cause the glue layer to come loose.

This can lead to:

  • bubbles in the floor

  • planks that no longer lie flat

  • parts that lift up

2. Prolonged moisture

PVC itself does not expand like wood, but prolonged moisture can cause problems.

When water remains on or under the floor for a long time, parts can deform. This especially happens at seams or small openings where moisture remains trapped.

What does water resistance depend on?

The extent to which a PVC floor can withstand water depends on several factors.

Floor thickness

Thicker PVC floors are more stable and often better resistant to moisture and heavy use.

Click-PVC or glue-PVC

Click systems are often water-resistant, but not always completely waterproof.

Glue-PVC lies completely flat on the substrate and is therefore an excellent choice for spaces where water regularly occurs, provided the floor is professionally installed.

The subfloor

A dry and level subfloor is essential.
Moisture in the subfloor can cause the glue to come loose.

The installation

Proper installation prevents open seams and weak spots where water can get under the floor.

 

What to do in case of a leak?

If water gets on or under a PVC floor:

  • remove the water as quickly as possible

  • let the floor and subfloor dry thoroughly

  • ventilate the room to prevent mold growth

  • have a specialist check if the adhesive layer is still intact if in doubt

A PVC floor can handle a lot, but prolonged moisture is never good for a floor structure.

Conclusion

A PVC floor is an excellent choice for kitchens, bathrooms, coastal apartments, and even for use on yachts. The material itself is completely waterproof.

In extreme situations like a leak, however, the subfloor or adhesive layer can cause problems.

With proper installation and quick action in case of water, a PVC floor stays beautiful for years — even if it gets wet occasionally.
