I'm planning to remove my old deck, and place concrete slabs 40x40cm instead. A few questions:
- Is it sufficient to put a gravel on the ground and sand on top of it? I thought this should prepare a good foundation for slabs.
- Should I be placing slabs right to the house foundation (it's standing ~50cm above the ground)? If slabs will be adjacent to the house foundation, will there be a risk of rain water leaking under foundation?

I have seen this done in better and worse ways.
