Most of the homes that were built during or before the 50’s and 60’s may not have rebar in their concrete slabs. These homes may have cracks on the floor tiles which indicate there are also cracks in the concrete below the tiles.

 

The lack of rebar in a slab will be more likely to allow one side of a crack to rise above the other side. This condition often creates a trip hazard.

 

Why is rebar put in concrete?

 

Two of the main reasons are:

• Reduce cracking in the concrete

• Add structural strength, especially tensile strength

 

Other reasons for rebar in concrete

 

• Helps keep one side of a crack from rising above the other side

• Can tie two separate sections or pieces of concrete together (i.e. at cold joints)

• Ability to reduce thickness of concrete. With rebar in a slab or wall there may be less concrete required, and the concrete may not need to be as thick

• Can help distribute the weight or load on the concrete to a larger area

• Helps hold the concrete together when it expands and contracts
