Building floor in shed

tractormarkb · Mar 4, 2009

I have a shed addition on my house with a dirt floot(Polebarn type) Now Mama wants to use it as a bedroom. I am looking for some idea as to how to raise the floor 6" from the dirt floor, insulate it and run pex tubing through it.the area is roughly 16x20.Any ideas would be appriciated.I can not get a cement truck anywhere near it(hills).

How about building a floor as you would a deck sink in some posts attach floor joists or attach joist hangars to existing studs install joists and sheeting also should use vapor barrier.

I have seen a trailer that is used by the person who has to get ready mix into an area where the big cement truck can't go! I'm not sure what company has them, but you might inquire at the big box stores, or the local cement company!
no, i'm not dreaming! I've really seen them!
I live near Pittsburgh, Pa. but don't know if they are used anywhere else.
As for the floor, i'd bolt a stringer all around the inside walls, sink posts in the area to be covered, run joists across, with steel end hangers, on the posts, and use large lag screws to hold the stringers against the outside walls! Then lay some all weather plywood across, and lay some kind of insulation on it, then install the flooring.
I don't know how you are going to heat it, but insulating the floor and walls will help immensely. And, use a double pane glass window installation
Once you get the floor attached to the walls and the flooring in, then you can double the inside walls, with fibreglas insulation in between the inner and outside walls! Have fun, and keep everything straight!

You've had some good ideas handed to you . I'd also add this ; before staring the floor , I'd haul in gravel (2B or 3A) , lay down heavy black plastic on the ground then spread gravel ontop of that . That'll make a cold barrier for the floor . You could also spread some loose insulation (pellet type for blocks) over the gravel . My kids have a room done like that & it helps keeping their own bedroom warm . Then if possible run a warm air duct to that room as the floor is built . Doing it now will prevent having to crawl after wards . HTH ! God bless, Ken

Crawl spaces & footings can be _very_ dependant on location - frost, snow, rainfall, soil type, temp & insulation needed.

I would not advise you at all without knowing a lot more details, and while you have some good advise below, I'd be scared to follow it for _your_ location, wherever that is, unless I knew that sort of thing worked _there_.

A 6 inch crawlspace is not really a good thing, you'd want enough room to crawl around down there & fix pipe, fix insulation, allow condensation to get away, etc. Anyhow here where I am, 6 inches would not be a good thing.

They can get cement anywhere one way or another, and a vapor barriored & insulated (blue or tough foam panels, not the crushable stuff) poured slab would sure be nice and take away a lot of concerns. Again, depending on your location.

Ya must be one of them hill-billy folks, making a pole shed into a bedroom, and if you can't get an average concrete truck even close, your really back in the Mountains, ((are ya into moon shine?))

all ya have to do is put in floor joist as high as you want the floor, and put in insulation, what's so difficult about that ????????

Poured concrete, if you have a couple of skidsteers in the neighborhood ask your neighbors to help you out. We hauled about a quarter mile with two, the driver said we moved faster than some guys pouring right behind the truck. I thick he said about 45 min. to pour 8 yard is what the company alloyed.

I would start with 6 mil poly and then use treated 2 x's for joist. I would use pink foam insulation [ 2" ] and then tunge &groove plywood

For all the ideas about putting in floor joists (and not pouring a slab)...without a perimeter foundation going down a foot or more, how y'all going to keep critters out of the insulation under the floor? Looks like a mighty cozy place to make a nest.

Howdy
Just build the floor and joists in the conventional manner, put chicken wire on bottom of joists to keep out larger critters. Next use 1x2 or 2x2 at bottom of joist to form ledge for 2in foam insulation then use pouring insulation to fill to top of joists. I've done it on my porch, works good, I also installed a direct vent wall furnace to heat the space, great thing about that is furnace uses no electric, so if power goes out I still have a heat source. Only problem so far is rabbits chewed through plastic lattice used to finish off outside of crawl space. Good luck.

Put you choice of sheeting on the bottem side. I'd go with tin.

you could rent a concrete pump trailer and the operator for about $400 or so bucks...thats how we did our basement floor.

Did a floor that size in an awkward spot a couple of years ago. Wife mixed and me and my buddy carried buckets. Lot of work but won't have to be done again. For the floor heating, used styrofoam panels with channels for the pex, then sheet metal and cement floorpanels and tile.
After that little episode, I'll hire a pump if needed again.

Sounds like fun to do with a 6 inch crawl space.
