How Deep Should A Column Footing Be?

The ground level of your home or office building is usually not very high. However, it might be difficult to get up there without assistance. If you are trying to do something like climb stairs, then you may need to have a little extra room. Because of this, the lowest floor of any two story building should be at least 7 feet and 6 inches off of the ground. That includes the bottom of any columns that may be holding up an awning or porch roof.

Keep in mind, however, that this is only a minimum requirement. If you would prefer your floor to be higher off of the ground, then you have the option to build it higher.

The Building Code

Before building anything, it is important that you check your local building codes. They may require that you do something differently, or there may be something in the code that helps you out. For instance, the building code may require that you add an elevator to your building if it is a certain height. Not only does this allow older people to get around easier, but it also makes your building safer for everyone. Other codes may impact the placement of your columns, as well as how much reinforced concrete you need in the foundation.

Before you start building, it is absolutely essential that you get a copy of the building code and familiarize yourself with it. Otherwise, you could end up wasting money and effort on building something that won’t be approved.

Foundation

Your house is going to have a foundation, which is basically the base of your home. It sits on the ground, and the rest of your home sits on top of it. Your house would fall down without it. Your foundation has three major parts. The first part is the footing.

This part goes into the ground underneath your home. Sometimes you have to put drainage pipes in the ground before you build so water can get out from underneath your home. Next, comes the stem wall. This is the part that goes up and against your home. It is like a big block of concrete that holds everything up. Finally, there is your slab. The slab is the floor that all of the rooms in your house sit on top of. It is nice and level so nothing is ever crooked.

The History of Foundations

People have been building homes for a very long time. The only thing that has really changed about the way homes are built is how strong the materials are and how they are put together. Even today, people in some countries still build homes the same way they did thousands of years ago. They mostly use the same materials, as well. The only difference is that back then they didn’t have access to steel or reinforced concrete.

They used wood and stone.

The Three Main Categories

There are three main categories for building materials. They are mineral, vegetal, and animal. Each one has its pros and cons.

Mineral:

The strongest of the three main materials is mineral. This includes things like stone and metal. It is great for keeping its shape. There aren’t many minerals that can’t be crushed, dented, or burned up if they are hit hard enough. Most minerals can’t grow back if they are destroyed either.

Building with minerals is also the most expensive.

These are some common examples of mineral building materials:

Stone: It is very strong, but can be heavy. It can also be difficult to cut and bore through. Unless it is granite, stone tends to be rather brittle. That means that it is more likely to break instead of bend. This means that sometimes columns made out of stone will have a tendency to shatter.

However, stone tends to be one of the more popular building materials. It tends to last for a very long time. Also, stone is usually one of the cheaper materials to build with.

Concrete: Concrete is made by combining stone and lime. This makes concrete stronger than stone, but still not as strong as metal. It is also much easier to work with and less expensive than stone. That is why it has become one of the more popular building materials. Some of the columns for your house will probably be made out of concrete.

Metal: Of course, the strongest material for building columns is metal. The problem is that metal tends to be the most expensive. It is also the heaviest material. It takes a lot of energy to get metal up into the sky, so builders only use it in certain situations. It is very strong and hardly ever crumbles, dents, or burns.

It is also very good at keeping its shape.

Metal is most often seen in the construction of train rails or large skyscrapers. They are rarely used in home construction.

The reason I bring this up is because you will have to decide which columns you want to use in your house. Each column has its pros and cons. It is up to you which ones will work best.

Please take a moment and fill out this column chart. The blue columns are the pros and the red columns are the cons. Next to each column, please write a short explanation as to why that particular column has pros and/or cons.

The columns:

Sturdy: Metal is sturdy and strong. It doesn’t bend or break very easily. It can withstand a lot of weight and pressure. Since it hardly ever crumbles, dents, or burns, it is very reliable.

Expensive: It is the most expensive material to use. Most of your house will be made out of concrete and stone, not metal.

Light: Since metal is so thin and lightweight, your house will be much lighter than it would if you used concrete. This is good for two reasons. First, it is easier to get your house up into the air using helium balloons. Second, if there is an emergency and you need to quickly get your house down, it will be a lot easier.

Not very strong: Since metal is so thin and lightweight, it can’t really support as much weight or pressure. This means that it might not be able to hold up all the stone and concrete in your house. This could cause a serious problem.

Metal is very good at conducting sound. This is why it makes the perfect instrument. The sounds that come out are very clear and crisp.

Metal is also very good at conducting heat. That is why cups and pots made out of metal can very easily burn you.

Also, because metal is good at conducting both sound and heat, it can be used to transmit and receive signals. Did you know that before the existence of electric lights, metal wires were used to send messages through big holes in the ground?

Metal is used in many things. Sometimes it is shaped into long, thin strips and formed into a cylinder. These are called metal barrels. Guns, swords, and other small items are kept in metal barrels for protection.

Metal is also used to make other items.

Did you know that a house made out of metal would be impossible? This is because metal can’t bend. To make shapes out of metal, it has to go through a process called shaping. This process makes the metal very weak. If you tried to make a house out of shaped metal, it would collapse in on itself.

The most common types of metal are steel and iron.

Metal from the ground is called ore. It must be dug up from deep underground. For example, iron ore is often found deep under the ground in a substance called rock. Once miners have dug up the ore, they take it to a factory. There, the ore is melted and shaped into different things.

Did you know that steel is made out of iron ore?

Metal didn’t always exist. In fact, it is a fairly new material. But as technology advances, people are finding more uses for it.

It is very strong and durable. It doesn’t burn or break easily. It is used in almost everything. There are three main types of metal: steel, aluminum, and titanium.
