Slab cracking around penetrations
I was hoping to see what others with experience would suggest.
My foundation is slab on improved grade. The mat in the slab is #3 rebar 24″ OCEW. I was wondering if additional reinforcement is recommended around pipe penetrations within the slab to help prevent cracking and if so what is preferable: 4×4″ steel mesh, rebar on diagonal, etc?
I have posed this question to the structural engineer but he won’t answer…I guess because its not a structural question?
Thanks. I tried to attach a photo for clarification.
