What is footing in Construction? A complete guide!

When constructing a building or a house, it is foremost to create an attachment of the soil and the foundation of the building. This attachment is known as footing. Before Pursuing further, let’s make a clear difference between the footing and foundation of the building. You might have heard it zenith times that a strong foundation is the pillar of a substantial building. Why is it so? The answer is a strong foundation is the part of the building’s structure that transfers its load to the soil’s foundation.

Foundations provide the layers of load to the soil having unlimited bearing capacity. Sometimes, people interchange the term footings and shallow foundations together. Coming back to the foundations, it distributes the pressure evenly so that the soil does not exceed its tolerable capacity. Now moving to the Footing in construction, it is necessary to prevent the settlement and spread the load to larger areas. Footing is a small part of the foundation made of brickwork and concrete.

What is the role of footing in construction?

It is an undeniable fact that footing in construction is necessary as it supports the entire weight of your building. When the footing is not done correctly, it may result in cracked walls,  cracked floors, and other construction-related problems. Sometimes, while constructing a residential building, the contractors do cheating by not pouring footings which may cause problems later on. When you know the health and condition of the soil is poor, you should take extra care of the proper placement of footing. In the case of retaining walls, decks, and other types of construction, a concrete foundation provides the best-needed support.

What should be the footing size?

Before answering this question, you must know that soil’s load-bearing capacity is related to the footings’ size. Both are related; footing needs to be spread widely if the ground has a low load-bearing ability. However, if the soil isn’t weak and robust enough, there is no need for strict footings.

The footing size varies and is based on the size of the building/house/ and the capacity of the soil; in case of heavy buildings on the weak ground need 2 feet wide footing or even more. However, in the case of the house buildings on solid soil, the footing required must be 2-3 feet wider.

Footings are shallow and deep, and it also depends on the soil condition. Along with the size, there are different levelling requirements too. You should try to keep both levels(top and bottom) equal.

Different types of Footing

Here are different types of footings and some information about them.

Isolated footing

Compared to other footings, these are pretty economical and come in squares, rectangles, and other sections. Contractors go for an isolated base when the soil has a high bearing capacity.

Stepped Footing

You won’t see such outdated footings nowadays, and as the name suggests, these footings would be stepped upon each other; it is known as Stepped Footing.

Sloped

Such Footing is created carefully to ensure top slopes of the building have been maintained at 45 degrees.

Shoes or eccentric Footing

There are other types of Footing called shoe or eccentric Footing. The basis of this Footing is a boundary.

Combined Footing

In combined Footing, a building usually has more than one column, and when the installation has limited space, the Footing is connected.

There are many other types of Footing, too and in this guide, we will further move towards the misplacements done while footings.

Misplacement of Footings

Sometimes, Footing gets misplaced, and you can see when the walls fail to align to the footing centre. Contractors need to be very supportive of placing the foundation wall at the centre of the Footing.

Bottom Line

Final thoughts related to the footing in construction are that it is pretty necessary for every commercial or residential building. Furthermore, you must try to keep a watch or talk to your contractors regarding it because exterior foundations and other walls like one of those basement walls need footings when you know it has the load-bearing capacity.
