Do I need rebar in a concrete slab?

Asked By: Lior Elrom Date created: Jun 18, 2022

Rebar is not necessary for every concrete project. The general rule of thumb is that if you are pouring concrete that is more than 5 inches in depth, you are probably going to want to add in some rebar to help reinforce the entire structure.

Do I need rebar for small concrete slab?

Do I need rebar for a concrete patio?

Do concrete patios need rebar? Even though it's possible to build a concrete patio without rebar, it's not recommended. All concrete is subject to cracks, but rebar holds all the cracks together and keeps the slab level and even. Without rebar, the cracks would become quite wide and the concrete would become uneven.
