Types of House Foundations

A foundation is an integral part of a building. Not only does it support the structure above, but it also prevents groundwater from the surface while keeping soil vapor away. As such, it needs to be sturdy and well built. This calls for some research when deciding which foundation to build for your house. Today, we talk about the three main types of foundations to help you make an informed decision.


#1. Concrete Foundation
This is a common and less expensive foundation that requires less preparation of the building. Because it features a simple installation, it makes it a popular choice among homeowners. It’s also loved due to its low price tag.

The builders pour concrete footing approximately 24 inches below the projected finish grade. Then, add two layers of concrete blocks to the footers. Once the blocks are laid, they will then install internal piping and add rock filer on top. Then on top, they’ll pour four inches of concrete. 


Advantages of Concrete Foundation
The main benefit of a concrete foundation is that it is cheaper. Therefore, if your budget is tight, you may want to learn all about the concrete foundation as it could be your best bet. Also, it needs low maintenance, which even makes it less expensive. 


Disadvantages of Concrete Foundation
Repairing it can be a bit costly. Note that your plumbing system is placed below the slab. Thus, should you need to repair your pipes, you’ll have to break your concrete slab first. But, thankfully, this is not a big issue thanks to technological advancement. Today, builders use a pex plumbing system that is easy to reach and does not damage the slab that much.

Another drawback is that a concrete slab doesn’t offer much protection to your home during bad weather. However, your contractor can prevent this by ensuring proper drainage of the structure to minimize water buildup. 


#2. Crawl Space Foundation
Such a foundation lifts a home some feet above the ground. Like the concrete one, builders will start by pouring footing, then lay blocks used for creating the foundation. These blocks support the structure walls.

Although this foundation may be cheaper compared to building a basement, it is a bit time-consuming. Benefits of a Crawl Space Foundation
A crawl space foundation fixes the accessibility problem of a concrete slab. Therefore, you can easily access your piping, wiring, and ductwork systems should you need to repair or upgrade. Also, the conditioning of the crawl space makes your floors warmer compared to building your floor on a concrete slab. 


Drawbacks of a Crawl Space Foundation

Unfortunately, this foundation accumulates moisture, which supports the growth of fungi and mold. Even installing vapor barriers may not be that effective. It’s why we advise inspecting your crawl space regularly for signs of moisture accumulation. And seek help from the professionals if you notice any signs. Again, it doesn’t protect your home from bad weather. So, in case of floods and storms, your home may suffer the consequences. 


#3. Basement Foundation
A basement is simply a hole, at least 8-foot long, that has a concrete slab. Traditionally, builders used cinder blocks to construct basement walls. However, this led to structural failures as time passes by.

To solve this, builders nowadays use concrete walls that are sturdy and resistant to many structural issues like integrity and moisture permeation.
If you’re planning to extend your foundation below the frost line, we recommend this foundation as it anchors your building. Therefore, it’ll maintain the foundations integrity and sturdiness. 


Pros of a Basement Foundation
A basement foundation gives you additional square footage at a cheaper cost per square foot. It is also suitable for smaller footprint homes as it helps lower energy bills by adapting to the changing weather.
Also, you can do repairs easily since your technician won’t struggle to access your homes utilities. Lastly, it offers protection from inclement weather. 


Cons of a Basement Foundation
It is expensive, therefore, not suitable for someone with a low budget. Also, flooding is a possibility, especially for those without a sump pump. Additionally, if you’re using it as a living space, you may be forced to think of other ways of bringing light into your space.
