To explain a little further, the footing is a standalone structure that ultimately provides support for the masonry foundation walls that are built “on top” of the footing. It is what separates your home’s foundation from the ground. The two most common types of footings are the perimeter footing and pier footings. We will dive into those in the next section.
As you can see in the photo above, steel rebar is simply steel that is melted into the shape of long tubes. The term “rebar” is short for reinforcing bar and is used in concrete to increase it’s tensile strength. Rebar is typically constructed with high yield steel by heating it to its liquid form and then shaping the tubes to spec. Steel rebar can last up to 80 years before it starts to decompose. This makes building with concrete much more stabile and long lasting.
