Furthermore, why do you need rebar in concrete? **Rebar** is easy to set into place before pouring the **concrete**. It helps to reduce the cracking and breaking that is common in **concrete** because of its brittle properties. **Rebar** provides strength to **concrete** and saves money for the purchaser since the **concrete** slab, blocks or building will last longer.
