Porch Foundation

We usually don’t think more about the porch foundation as it is not visible. When one gets their house erected or constructed, they tend to pass over the foundation of the front porch. Such negligence could lead to serious unwelcome consequences. To avoid such difficult situations, the construction of the front porch should be mandated.

As often as not, we have seen the porch falling off, and failure takes place. This is precisely why one must make it a point to lay a strong foundation for building a porch. In this article, we will be delving into porch foundations and how to build a strong porch foundation for your house.

What Is a Porch Foundation?

The Porch foundation is a base that is constructed from Concrete to provide stability to the porch and prevents any settlement or failure of the porch.

There is not much of a difference between porch foundations and the foundation over which a house is built. A porch foundation must hold up the weight of the roof, railings/grills, columns, and others alongside the porch itself; one cannot afford to rely on a porch foundation that isn’t durable.

It is very important that a strong foundation be constructed for the porch and the time and materials required for the construction of the porch foundation are not much expensive.

Consider the following before going ahead with the front Porch Foundation.

There are several pointers that you need to take into account before building your front porch foundation, and those pointers are detailed below:

Geographical location: The place you reside plays a crucial role in a building that is a front porch foundation. If you happen to live in a place with uncertain and unstable water and soil conditions, there may be a calling for deeper porch footings, layered concrete, and thicker walls.
If your area is prone to frost heaves, footings may be buried just below the frost line.
Porch Weights: The next major consideration is how much your porch weighs. The foundation must be able to stand the weight of your porch, furniture, and others that you will be putting on the porch. The porch foundation should have a good load-bearing capacity so that it can bear the loads and does not settle down.
Slopes: It doesn’t matter if your area is slightly sloped or entirely flat; either way, the foundation has to be stable to be able to thwart any possibility of damage to the house. The area where the foundation is to be constructed should be leveled and compacted properly. For steep slopes, it is required to construct piers that rest on the concrete slabs deeply into the ground.

Start with digging the holes up till the frost line; the depth may vary, ideally, it would be somewhere around 4 inches deep.
Stick a foundation tube in the hole until it reaches 3 feet down. The cement would scatter through the tube, reaching the foot of the hole.
The next step is to mix the cement and sand, ideally, the ratio would be three parts of cement to one sand and add just an average amount of water to it, so it doesn’t turn out to be “too watery.” The consistency of the cement has to be thick, so it scatters abroad.
Start cramming the tube with concrete and once it touches the foot, add two pieces of rebar to the cement. Continue adding it every 6 inches until the tube is full. Avoid going overboard with the cement/concrete.
