Stego Vapor Barrier / Radon Mitigation

S2EP05: In this episode we talk about vapor barrier and radon mitigation for the basement livable spaces. We use Stego Industries products and have to say we are very happy with their speedy service, quality, and set of products. Note we are not sponsored by them but we do highly recommend their products.

We wanted to get the slab concrete poured so we worked very hard to get all this installed, even working at night as it is a silent application! We are driven alright! We show you how to apply the vapor barrier and the different applications of the Stego tapes.

I don't really mention much about the use of XPS insulation as expansion joints, you will see us apply it. The key is that this is a "raft" slab, in other words it is disjointed from the main foundation. The expansion joint allows this by also absorbing the expansion and contraction of the slab independently of the main foundation. The slab is insulated underneath so the expansion joint allows us an extra thermal break from the rest of the foundation. Since we will use radiant heat this will be a great energy savings when the house is done.

We finished installing #4 rebar at 32 O.C. for the slab for reinforcement. It might not be clear on the video that the rebar goes near the center of the concrete. Our incredible concrete crew raises the rebar as they pour the concrete. Just be aware that it does not sit flush against the vapor barrier. The concrete itself has fibermesh for greater reinforcement and would you know that slab concrete is harder than typical foundation concrete?

The final step with the concrete in place is to apply acoustic sealant to the control joints of the concrete.
With this we are off the ground!
