Vapor Is the Trojan Horse of Moisture in Concrete Slabs

Do vapor retarders cause curling of slabs-on-ground? A. No, this myth has been entirely debunked. In fact, concrete slabs placed directly on plastic curl less than slabs placed in contact with the ground.5 Q. When a vapor barrier is used under the concrete slab, is moisture no longer a concern? A. A vapor barrier is a very good start. When ...
