- We have a floor! This video we removed the OSB sheets that we used to make the concrete forms and the concrete looked great! Next step was to put down some 6" foam sill seal, next drill the holes for the sill plate, or mud sill, for this we used 2x8 pressure treated lumber. After this was to build the girders that will support the joists, floor and the whole house, for this we used 2x8 lumber and sandwiched three board together to make a super strong support. Next step was to put the rim board all the way around and then we started laying in the floor joists. Once the joists were down we put the 3/4" OSB subfloor panels down, but before this we layed down a thick line of subfloor glue and we screwed down the sheets of OSB. The OSB sheets are exterior rated but we rolled on a nice coat of wood sealer for extra protection.

How would you get underneath your house, if you have to fix something like plumbing?
Hey, great question! The house has a utility room with the water heater and electrical panel, and in that room there is a 2x2 panel in the floor that can be lifted so someone can go under the house if needed.
did the OSB have a release agent to help the concrete not to stick to them and make them come off easier?
No release agent, it just fell right off.
@@slothconstruction awesome thanks!
Where were you fishing at?😁
Small lake/camp ground named o'haver
No blocking between floor gurders ?
No plumbing under floor ?
On this floor the joist span is short so blocking in-between isn't needed. For the plumbing it was all put in once the house was up and dried in, so under the floor is all the water lines and drain pipes
How are you attaching those wood support beams to the concrete pillars underneath? And how do you know how many you need to support the floor/house?
Hey good question! The support beams are not attached to the concrete at all, only to the wood girders. The supports are held in place by friction, and the weight of the house, once the house is complete the supports are locked solid in place. To know how many supports to use, it was shown on my foundation plans. I let the engineers calculate that part.
@@slothconstruction That's for the info! Is there a special kind of company for foundation plans or do you just go to a contractor?
@@LabSkaterPussies I got my plans from a online house plan website and all plans come with foundation plans. If you had your own house plans you could send them to an engineering company and they could create a foundation plan based on your plans.
What was the liquid you painted on the subfloor?
We used Thompson water sealer
Please what was that you poured on the floor and why
We put on a wood sealer, the same thing that people paint onto wood decks. It was the rainy season and we had to water seal the floor since osb doesn't do well with rain.
