Concrete is one of the most powerful mixes man has made and allows us to create the huge structures you see today. However, concrete has relatively low tensile strength and that can make it unsuitable for certain uses. An easy way to overcome this problem is by reinforcing it. You need to reinforce concrete when you need better tensile strength, need to reduce the chances of structural failure and when you need to curb cracking. If you construct a structure or building that will need to endure high working loads, concrete reinforcing is the perfect way of helping it endure these loads.
