Hi Dale There was forming at the back or rear of the shed and down both sides and at the front. There is an expansion joint in the middle and one at the front before the apron.
We do not need any packing under the slab but reinforcing mesh right through. The screed was a piece of steel channel which went across the width, we had to let the cement go off before we could float it off. The edges have a rolled off edge to give it a finished off look. It took a bit of setting up to get the levels right but after that it went ok, I used a four foot sprit level. You need a sighted person the help you with the screeding to tell you if it is ok. Can a totally blind person do something like this definitely not, you need a sighted person to both set up and screed off and also to finish floating off so it is not mucked up. Concrete is very expensive and you get one go at getting it right before it goes off. When I get the door on I will then have five garages 2 under the house and 3 in the back yard, and that is all along one side of the yard taken up.

Ray, How did you form up the concrete? I was wondering too what you used for leveling the form (if anything)? My level device is pretty short for something that size. Do you include some sort of expansion joints or stress relief joints to keep a platform of that size from cracking up? Do you lay down a layer of gravel before pouring a bed like that? Between the frost and changing bulk of of clay as it saturates and dries out we have to go to a lot of trouble over a slab that size.

Hi All Well the Bob Cat made short work out of digging out the garage floor. When he finished digging his small tip truck had an overflowing load. In when the reinforcing mesh, and two and a half loads of a Mini Mix Concrete Truck went in. After screeding off the mix and finishing the concrete it already looks better than it did before. I knocked some star picket posts in around the outside of the wet concrete and placed around this some pool fencing to stop the dog from running on the cement. I will wait for a week to let it cure before removing the fence and then moving on to the door.
