Many “solid” building materials such as wood, brick, concrete, or gypsum board offer little moisture protection due to their porous nature and require vapor barriers in such critical applications.

A: A vapor barrier is used under concrete slabs to prevent moisture migration from the soils. Concrete must have a capillary break or the concrete will remain damp for years.

Another problem is hard-troweled concrete, which limits the water vapor passing through the slab, causing greater challenges once the building is buttoned up and the HVAC system is turned on.

If the floor in your home's garage always feels a little damp, you may be concerned that something is wrong. You should know the source of the wetness first.

A vapor barrier was not installed at the Fitch Family Indoor Aquatic Center site before concrete was poured and must be corrected.

Like a slab floor, the basement floor will be lined with a 6-inch aggregate bed followed by a 6-mil polyethylene vapor barrier. One to two inches of foam board can go on top of the vapor barrier ...

If you're installing concrete slabs in a basement or another area of your home, you'll also need to install a vapor barrier to add protection. While not strictly required, you also need to add a vapor ...

Based on application, vapor barriers are majorly used for under-slab applications due to higher chance of ingress of vapors or moisture from soil into the building structures through concrete.

The global below-slab vapor barrier business is highly consolidated, with a small number of large-scale vendors controlling majority of the market share. Key below-slab vapor barrier manufacturers are ...

Polyethylene Vapor Barrier Films Under Slab Market Overview: In 2022, the market for polyethylene vapor barrier films used under slabs was valued at USD 1.59 billion.

The use of polyethylene vapor barrier films beneath concrete slabs is a vital component of building envelope systems. These films, typically made from High-Density Polyethylene (HDPE), are placed ...
