Down in the basement, carpet over top of the concrete let pull back this carpet and show what take place underneath the foam, under pad. Look at the mail do and mold of the back side of that foam under pad, caused from cold concrete moisture wicking up through concrete and venting itself into the foam leaving that white residue behind which really causes real problem with anybody with allergies. What is it caused from? Well the cold, the moisture in fact, look what the moisture will do with the hardware on the by fold doors. The temperature of the floor 67 degrees Fahrenheit approximate 10 percent colder that you would have find during a heating season. Now being the summers you can imagine how cold might be in the winter time
Male: One find is a multi dimple structure as we see here, manufactured of high-density polyethylene material. We place this material on to the concrete floor and essentially the multi dimples create a thermal barrier of air underneath the flooring in other words we put the plywood material on top, which is creates a sandwiching affect with air underneath.
Male: Stopping mildew
Male: Exactly, simply take the rolls roll them out and you can overlap as like that and also the material is very easy to cut with a razor blade knife. You may occasionally in sometimes find because of the curl and the natural curl material that put piece of tape here, a piece of tape there
Male: The next thing down goes the plywood, let us be fairly strong with 3 inch plywood on top
Male: Sure the strength factor is incredible you can actually get up to a 15,000 pounds per square foot rate ratio with the plywood on top. We use a masonry drill bit and a hammer, a rotating hammer drill
Male: With the depth gauge
Male: Yes with the deep thing as you, know exactly how far, to go in to the concrete that correct that is correct. Then what you do is once you drill into the ply wood surface board then the ward ford air gap into the concrete you end up going down in to the concrete like that then you take your fastener, who works for fastener you put it down in there
Male: Flash with the top of the plywood
Male: That’s correct, then the heavy hammer and you just wrap that down
Male: But if you plan them putting vinal flooring down like tiles or vinal then they multiply approved under plate plywood would be screwed on top. Well the carpet is back in and oh does it ever feel nice and warm and cozy down here 79 degrees what a difference.
