Design follow and placement of vapor retarders has become the topic of A great deal debate for quite some time. Some practitioners believe that concrete placed right with a vapor retarder will bleed excessively, warp and crack a lot more routinely, and choose for a longer time to concrete contractor haslet dry than a slab placed on a compacted granular subbase.
