Keeping it Dry… Moisture Barriers for Carpet

Depending on your performance requirements, moisture barriers are an integral part of choosing and installing carpet. Designed to be installed underneath the carpet and over the pad, or attached to the carpet itself, having a moisture a barrier provides a layer of protection from liquid from penetrating through. Over time, this can extend the life of your carpet. Though the price may be slightly higher, there are several reasons to consider a moisture barrier with your carpet or carpet tile.

  • Manage Spills or Stains

Even with a concrete subfloor under your carpet, it is important to have a moisture barrier. Water or other liquid can penetrate and erode the concrete so it’s important to keep it protected. Stains can be a result of liquid trapped beneath the carpet that may have soaked into the backing, however, with a moisture barrier under the carpet or attached to the backing of the carpet, this kind of staining won’t be a problem.

  • Mold

Even though spills appear dry, mold can grow under the carpet if the moisture remains. This can cause problems with rot and air quality. Moisture barriers are essential for keeping any mold at bay.  

  • Softness Under Foot

Moisture barrier carpet padding adds an additional layer of comfort under foot. The thickness of the pad gives the carpet a softer and more soothing feel.

IMPORTANT: What a Moisture Barrier Will NOT Do

It’s important to keep in mind that a moisture barrier is NOT disaster-proof. Any major flooding or leak events can come under floors or walls. A moisture barrier will help with surface spills and small amounts of liquid but will not withstand submersion.

Carpets to Consider:
