We are building a semi-finished house. Could you tell me how high the slab should be on the crawl space and in the garage? It seems that the DTU is 18 or 20 cm, my driver speaks to me of 16 cms.
You may have heard me denounce, on the radio, the fact that the DTUs (unified technical documents) is not a legal obligation and as such, is not freely accessible, to businesses, as individuals, except for safety-related sectors such as gas, electricity, etc. I am not able to give you the thickness of a slab on crawl space without knowing the staves. But what you can do is to include in your construction contract a compliance with the DTU, which will engage the company that will carry out this part of the work.
