I have a project that calls for the installation of footers under an existing 4-5 in slab.
I have done this before (did a trench under the slab and the fill with concrete) but the problem then was that with shrinkage there was a small gab between the footer and the slab and I was wondering what good the footer is doing if it is not fully supporting the slab.
1. Am I too paranoid
2. Is there is a way to pour the footers so that it will really provide support to the slab
3. Anything else.
Thanks
Erick
