    I have 6 mil plastic and I have used it as a tarp to cover firewood, to put under spray painting projects, but mainly I use it over PVC hoops that I have over my 3ft wide garden beds so my flowers and winter crops are covered during winter. So you could do a lot of things with your extra 10 mil.

    Good video and 'reinforcing' in regards to the vapor barrier over the rigid board vs taping all the rigid board seams. I liked that, Also...curious about the slab thickness. 3/8" bar on top of 1 1/2" or 2" bricks then 3/8" tubing. Is a 4" slab enough, or would you recommend 5"?
    I did like the 1'-0" rebar grid for reinforcing and pex layout. It's tedious work, but I think worth it.

    • @MasonDixonAcres
      @MasonDixonAcres  Год назад

      Ours is 5-6". Even a 2' rebar grid would have worked okay for layout, but at 1' every tube run is supported which helps during the pour (the mat gets trampled)

  • @andysparks7381
    @andysparks7381 Год назад

    Hey, you're doing great! Did you consider using the wire mat reinforcing coupled with fiber concrete instead of rebar? Much easier.

    • @MasonDixonAcres
      @MasonDixonAcres  Год назад

      I did consider it, but it's really flimsy unless you get the expensive stuff which was more than #3 rebar. I do have fiber concrete anyway. The rebar grid on chairs actually springs back into place after being stepped on.

    Hi, I was wondering if the edge of the slab will rest on the ledge of your stem wall? Is that why you made that ledge with the smaller cinder blocks? If the slab doesn't rest on stem wall, then how are they connected so the slab doesn't shift around? Finally, why does the insulation go all the way down the inside of the stem wall, doesn't the insulation under the slab isolate it from the stem wall? Thank you for documenting this process!

    • @MasonDixonAcres
      @MasonDixonAcres  Год назад +1

      Insulation extends down for frost protection. The slab does not rest on the interior wall, it rests on insulation which rests on compacted stone base. The small top course was so that you couldn’t see block at the edge of the floor in the finished assembly. Aside from the interior wall footing the slab doesn’t serve a structural purpose and doesn’t need to be connected to the wall directly. In fact, it saved us a lot of cracking having them isolated via insulation, which worked as a control joint. We didn’t cut control joints.

    What’s the consensus about the insulation foam under heavy loads (like a truck moving in and out every day). I imagine that eventually the foam gets squished and subsequently the floor starts cracking.

    • @MasonDixonAcres
      @MasonDixonAcres  Год назад +4

      That doesn't happen, the foam supports 25 psi and the concrete won't transmit that much of a concentrated load. You can actually use mineral wool insulation under a slab the same way.

    Any feedback on why you put insulation then vapor barrier? I see both ways online but no information on why people are doing each option.

    • @MasonDixonAcres
      @MasonDixonAcres  7 месяцев назад

      Two main reasons:
      1- Didn't want any concrete getting under the insulation, causing them to float during the pour
      2- Vapor barrier is better protected from punctures by the crushed stone

  • @user-jy9sl7iz2b
    @user-jy9sl7iz2b Год назад +2

    The vapor barrier has to go underneath the insulation board to keep the moisture from coming up from the ground

    • @MasonDixonAcres
      @MasonDixonAcres  Год назад

      It works in either location. I put it above to a) keep rain from getting between the insulation board and vapor barrier and b) make sure the boards didn't float during the concrete pour

    • @ryanrich9186
      @ryanrich9186 Год назад

      If the vapor barrier is so cheap why not do it in both locations? I'm oozing to get educated in this because we are planning our house build, and every bit I can do is a bit I don't have to pay a crew.

      I know you watched this awhile ago, but they didn't have a load bearing wall there because it's a garage and it would've interfered with their plans/where they park their cars, but they needed to support the ridge beam which will be the horizontal beam right at the top of their roof--so they are installing a pole there that will support the beam and take up less space then a wall. Hope that answers your question.
