Importance of Underlayment on Concrete Subfloor

Underlay comes in between the subfloor and the top flooring. It comes in different models and designs, serving a couple of functions. While using it is overkill and may not be necessary for some subfloors, in subfloors like concrete, it is a necessity. Sometimes, a combination vapor barrier underlayment (a vapor barrier put after the main underlayment before the flooring) is even used in concrete flooring. Other times, some use waterproof underlayment for the flooring.

Let’s see some importance of underlayment:

Wear Resistance

Friction between the feet and the concrete subfloor can cause wear and tear, and as such, the vinyl plank starts filing out. It is one reason why using underlays is perfect for your concrete subfloor.

Cushioning on the Feet

Underlays are designed to cushion the feet and make walking easier.

Moisture Barrier

In concrete subfloors, moisture usually sips from the ground to the concrete, and when this gets to the top flooring, it spells disaster. You begin to see cracks and molds, and the vinyl plank starts pulling off or breaking out. No wonder an underlay for vinyl flooring, not just any type, one that is waterproof, is highly needed in a concrete subfloor.

Sound Insulation

When underlays are sandwiched between the subfloor and flooring, it acts to buffer the impact of sound so you can work noiselessly around the room.

Moisture gets through the concrete to the top of the top flooring. Concrete can also become heated up and heat is transmitted to the vinyl planks. The underlay can act as a barrier to prevent too much heat from being absorbed into the top flooring.

  3. Prep the subfloor by scraping, smoothening out, and vacuuming dirt.
  4. Patch up any holes or open spaces to make it level.
  5. Roll out underlayment over the concrete floor, give at least two inches up the wall for moisture protection, and tape down the underlayment to the subfloor, smoothening with your hand to avoid any air gaps while you do so.

Factors to Consider When Buying a Flooring Underlayment

There are various types and makes of underlayment that serve several purposes like flooring for bedrooms, flooring for hall roomsflooring for bathrooms, kitchens, etc. However, it would help if you looked out for some properties in the underlayment for the vinyl plank flooring in the concrete subfloor.


Since there will be a lot of foot traffic, you will need to know how much weight will compress the underlayment. Make sure the underlayment you get has passed compression set testing.

Moisture Absorption

It is one of the most important factors you consider in your choice of underlayment on a concrete floor. Because concrete seeps out moisture always, some underlayment is designed with a built-in moisture barrier others are not. Be careful to choose one that absorbs moisture or prevents it from getting to the top flooring.

Sound Absorption

Generally, underlays are helpful in the buffer of the impact of sounds that results from the friction of the soles of the feet and the top floor and flooring.

Made from Non-Toxic Materials

Ensure that the underlayment is not made from toxic materials hazardous to health.

Ease of Installation

Also, consider this before you make a purchase. It’s best to go for something that is not super complicated to install. Choose something durable, affordable, and easy to install.


It should be thick enough to cover up minor unevenness in the subfloor to give a smooth and seamless finish when the flooring is installed.
