Hello, I'm going to make a 100mm foundation slab for a single-story house and am considering the reinforcement mesh. Should it be 6mmx150 c/c (about 390kr each) in the mesh, or is 5mmx200 c/c (about 229kr each) sufficient?

Reinforcement must not be under-dimensioned; concrete cracks in these cases. So stick to 6mm.

Thank you, dejmon!

I am unsure if I really need 6mm, anyone else with experience on what you have put in the base plate?
 
Now maybe this might be a thread hijack but... If you have an older house where the floor has been broken up and you're just going to cast a new one on top of new drainage and insulation (about 25 sqm), does 5*200mm work? There, you can't really talk about any load, right?!
