I am building a pizza oven and kitchen area in my garden. I am trying to work out how to lay a 2m*2m concrete slab.
My calculation for the weight (that the concrete slab needs to support) are
Dense bricks: 70 * 18.2kg = 1,274kg
Concrete slabs: 13 * 15kg = 195kg
Pizza oven: 1 * 50kg = 50kg
I did some research to find out how much concrete (with reinforcement bars) I need but it may turn out the bigger issue is what the concrete will be laying on (how much weight a specific sized concrete slab can carry?)
How do I determine this? In my case, I want to pour the concrete slab over mud, which I would have dug out to size (with a timber frame as well). I was hoping to pour a layer of gravel down but I'm not questioning if that is going to be enough.
I believe our soil is quite chalky.
How do I prepare the ground before laying the concrete slab in the UK?
