No way to get a concrete mixer back there
I didn't want to push a wheelbarrow back and forth
I didn't want to pay for a concrete truck and cement pump
And I wanted to do it an hour or so at a time, if it took a year it didn't matter
And I had to use the shed during that time...
So I decided to pour cement pavers and stock pile them until I had enough for the whole floor and could lay them.
You'll notice from some of the following photos that my shed is a little unusual.
Step 1: Build a Form
For my shed I needed nearly 30 pavers of this size. For the first 10 or so I made a form that held a single paver but when that form needed to be replaced I built one that held three. Both of these forms had issues, I would build forms of two next time. The single was slow and the triple was VERY heavy to turn over and the middle paver was hard to get out.
I also found a float handle and screwed a bit of plywood to it for flattening off the pavers... any bit of wood would work just as well.
Step 2: Pouring Pavers
Hopefully all that will help the cement last longer but I didn't notice any outward variation.
Step 3: Prepare Floor
When the shed was built I'd been excavating for a retaining wall and was breaking up a lot of rock with a pick so I thought I'd use it to keep the dust down. It isn't needed to help support the pavers at all.
Step 4: Sand
Step 5: Sand Base
I then hauled in the sand and spread it out. To get it uniform I dragged a 10 foot 2x10 across it a couple of times. This help me see where the low spots were, unfortunately I was running low on sand so I had to steal some from my Daughter's turtle... she's only three, probably won't notice.
Step 6: Lay the Pavers
I wanted the front to be flush with the door so I started there. Also I didn't care if there were gaps at the end or sides since I planned on putting benches, cabinets, etc against the walls.
After the two center rows I did some more measuring and I contemplated moving the rows to one side or the other. In the end I left it as it was and filled in the rest of the floor.
Step 7: Cutting to Fit
Also some advise I got that I should pass along (I didn't follow it, stupid me) is to look around the tool shops for an off brand, super-cheap circular saw to use. The dust that is produced can get sucked into the motor and really kill it.
I filled almost all the remaining space then ran our of pavers. Since there were just a few small gaps left I filled them with gravel.
Step 8: Filling the Gaps
The drier that this sand is the better. It needs to flow down into the gaps. Mind was a bit damp and I'll have to do it again in a month or so when it all settles.
I just dumped the sand and pushed it around with a push broom until it disappeared.
