Guys,
This question will make you laugh, and show why its important to do things properly so they don't come back to haunt you!!! hahah
Some time ago, while I was having concrete delivered for another job I was doing, I poured a C25 slab..... the idea being that I might need another shed/workshop at some point, so it would save me getting a delivery of concrete twice.
Now the time has come that I DO need another workshop/shed, but I have been offered a load of bricks for free, so was considering building a single skin shed from bricks rather than buying some wood etc.....
However, because I never intended to put anything more serious than a large shed on the slab, I just poured the slab any old how, without going about it properly. Obviously if the slab cracks or moves badly with a wooden workshop on it, its not going to matter too much, but a brick-built would suffer the consequences far more seriously!!! That will teach me for not doing things properly!!! hahahah Oh well.
SLAB SPEC:
The ground slopes so rather than dig out loads of earth to level the site, I dug out 100mm in which I compacted MOT1 to 80mm deep and then shuttered the slab to make the top of the base level. The slab itself thickens from 200mm to about 400mm to make up for that slope.
Its 2.9m x 2.9m. I also had a load of 6mm Mesh spare, so I just chucked it in, but it wasn't big enough to cover the whole slab area, just the middle 2.4m. So give or take, approx 350mm around the edges has no mesh in it.
So what do you think? I know its a mega bodge as far as the slab goes, but as it was only for a wooden shed it didn't matter at the time. If no-one thinks I may get huge cracks appearing, I could use the free bricks. If it sounds really dodgy, then a simple wooden shed (as per my original plans) will be the way to go.
Cheers.
