## FAQs

Why is it important to design concrete pipe to the 0.01-inch crack? A: Reinforced concrete pipe, like other reinforced concrete structures, is designed to crack. It is well known that while concrete is very strong in compression, its tensile strength is so low that it is considered negligible in design.
