Slab Day

Yves is going to show up at 7am to help prep for the concrete pour at 8:30am, and he expects to be here most of the day.

I'm up at 6:15am, and after breakfast, I'm out the door to meet Yves.
He points out that there is no plastic on the base, so we begin by removing all the rebar, mesh and bricks (so much for my work). He's got enough plastic to lay down, so after cutting and laying it, we restore the bricks and mesh to their original layout - with the exception of the mesh. I had it out to the edge of the form which is wrong (it'd be poking through the sides of the slab). We bring the mesh in from the sides of the forms some, he cuts it in many places, and uses the cutters to loop/tie it all together.

The drain box is then levelled and set to be 3/4" below the form walls so there's a slope for future floor water to drain. Yves then drives 4 pickets into the ground surrounding the middle section. We snap some chalk lines to line up level with the forms, then nails are driven sideways into the pickets for reference later. We're now ready for the concrete.

The concrete truck arrives at 8:35am, and soon discover it's an older truck with a short reach for the spout. This means he has to back up as close to the form as possible and is still only able to get within about 8 feet of the rear form. So, first we try the wheelbarrow, but the tire pressure is too low, so we get out the rakes and push and pull the concrete into place. It's much heavier when you're doing the job, and we are sweating by the time the rear section is poured.

Yves gets out his 2x4 and starts leveling the concrete in the rear section. He trowels around the pickets and their side nail as a guide, and now has a level area to span his 2x4 to the form wall. The pouring, spreading, trowelling and leveling continues until we're at the front wall, then discover that there's lot's of concrete left over. We quickly get some boards together to build a rough form in front for a sloping pad about 8x12 feet leading to where the garage door will be.

At just after 10am, the concrete is complete, and Yves goes to work with the bull float. He's obviously done this before, cause he's doing a great job already. To prevent the sloping pad being too slippery leading into the garage, Yves gets his old broom out and brushes some wave patterns into the concrete for traction.

After getting the slab pretty smooth with the float, he finishes off around the forms with the edger. Then where the garage door will be, he slopes it down to the outside so water won't sit there in the future. I gather my hold down bolts for the walls and sink them into the concrete around the perimeter.

By noon time, the slab is setting up pretty good, so we break for lunch, I run into town to grab some beer and Dixie Lee. We sit on the tailgate and devour the food, and the beer goes down pretty good also.

Now the polisher is fired up to do the initial run with the float attachments to the blades for the first polishing. Time crawls along now sitting and waiting for the concrete to harden. Yves brought his large spotlight thinking he will be here till dark. A couple hours pass, and the broad, rough floats are removed to do the finer polishing. Now the slab is looking great after this pass, but 2 more polishings are in order. Hours float by, and so does the polishing, and by 7pm the job is complete....Yves doesn't have to stay after dark.

I'm supposed to let everything set for 3 days, but building is 7 days away, so all the better. Rain will help set the concrete even more, and that's what happens on the 4th day.

Slab Prep


I find out that Yves will in fact be doing my slab on Friday, so although it's lousy rainy weather, I've got no choice but to get the sight totally ready. I get all the brick pieces in place and lay the rebar mesh down on top. The drain box I had Raymond make for me is now centered over the drain. I shore up the forms to make them as accurate as possible.

Forming

After getting false info that Raymond planned to do the concrete work today, I spend the morning putting the 2x6's together into 20' and 24' lengths, then tie everything together. It doesn't help that the lumber is not perfectly straight, cause this will influence my final laser shots, since the intent is to align the tops of all the lumber at the same level.

After joining everything together, I see where the high/low spots of the gravel are, so mark those areas, and also discover that the south-east corner is a few inches too low. So, I go to the north side to shovel some excess gravel into the wheelbarrow and add to the low area. Would be nice if I had the final small truckload of gravel!

Levelling and Tamping

I'm leveling the gravel, then the civil boys from work drop by with their surveying transom to take some shots of my corners - 3 are the same, and one is 1/2" low, and the drain is 1/4" high, so pretty damn good I must say.

I spend the rest of the day trying to get it better, then the gas-powered compacter does a good final job. The south-east corner looks a little low though.

Time to go get some 2x6's for the forms, and wire mesh for the slab....$173

Cut er down

Well I decided since my small load of final? gravel wasn't being delivered, I'd get the plow in again. He pushed a layer off the top to spread it out a little more, so now I should have a wider area to build on. Tomorrow I go at er again.

More gravel??

I contact Lawson up the road and he has some gravel to sell me - a pickup load for $10. I take it back to my place and spread it, but still don't have enough. I return to Lawson's gravel area, but he's not around, and not answering the phone. I finally get ahold of him and he tells me I'm better off getting a small load and I agree, but 2 days elapse and still no delivery.

Pythagorus and rectangles

OK, I measured 20x24, but after spending time spreading and tamping, I decide to check the diagonals, and they're 3' off!!
I had this all squared away before the tractor spread it, so all I can think of is the tractor didn't spread it along my paint markings.
Doesn't help that I'm running out of gravel.

After relocating some of the gravel, I don't have enough, and LCL is not open to deliver me more.
