Carpet Over Concrete Moisture

The floor outside the bathroom walls is either carpet or bare concrete neither have moisture.

Carpet over concrete moisture.

This standard calls for the use of a thermo hygrometer with in situ probes to measure the. For below grade slabs assume that the concrete floor will get damp at some point. Many carpets and carpet padding are vapor permeable so if your concrete basement is showing moisture it can continue to evaporate up through the pad and carpet. Moisture barriers as the name implies set up a protective barrier to block moisture from reaching the pad and the carpet.

Installing carpet over a basement concrete cement floor can be a simple project and requires very few tools to accomplish. With an insulating carpet above the slab the slab temperature can be low enough to create a mold problem at the deeper levels of the carpet. They look similar to carpet padding but they have a plastic film on the surface to block moisture. Over time hydrostatic pressure will force that moisture upwards and can cause bubbles in surface treatments and cracks in covering materials that are installed above it.

The solution which you already alluded to would be to install 3 4 1 of eps over the slab held down with a subfloor tapconned to the slab. You then have two options depending on your circumstances.

If excess moisture is present in a concrete slab when an impermeable surface treatment is installed it will become trapped under that covering. Another part of the basement we have a vinyl floor product that interlocks without grout not sure if it was glued with no issues. Seal the floor either chemically or via membranes this creates an impermeable barrier between the sub floor and your flooring which means moisture cannot penetrate into your flooring. 1 to prevent moisture migration up through concrete substrates located on and below grade and damage to installed floor coverings the concrete slab shall be protected from ground moisture and hydrostatic pressure by the use of an industry approved vapour retarder moisture barrier or waterproof membrane having a permeance of less than 0 3 perms 0 2 metric perms in accordance with astm e 96.
