Becky, a fictional homeowner, likely selected a slab foundation for her new home due to factors such as cost and minimal upkeep. However, it can be assumed that she thoroughly researched her options before making a decision. The purpose of this example is to demonstrate that there are many homeowners who make similar choices, and after reading this information, to equip you to better decide which type of common home foundation best suits your needs.
When building or purchasing a new home, it’s important to consider the type of foundation that will be used. The three most common types of home foundations are slab, crawlspace, and basement. Each of these options offers its own advantages and disadvantages, and it’s important to weigh the pros and cons before making a decision. Ultimately, the foundation chosen should be able to support the structure above it, as well as act as a barrier to keep water and soil out, ensuring that groundwater is kept at bay.
When building a new home, one of the most important decisions to make is the type of foundation. There are three main types of common home foundations: slab, crawlspace, and basement. Each type offers its own advantages and disadvantages, and it’s important to consider your budget and personal preferences before making a decision.
The Slab Foundation
This type of foundation is the most common and requires the least amount of preparation on the lot. Installation is simple, making it a popular choice with a low-price tag. The process begins with concrete footers poured 24 inches below the expected finish grade. After pouring the footers, two layers of concrete block are laid atop the footers. All the internal piping is installed after the blocks are laid, and a rock filler is added.
Finishing touches are made by four inches of concrete poured on top. Advantages include low cost and minimal maintenance, but disadvantages include minimal protection from storms and other extreme weather conditions, and expensive repairs, as the plumbing systems are installed below the slab.
The Crawlspace Foundation
This type of foundation is elevated only a few feet off the ground and is less expensive than a basement. The process is similar to slab foundations, with a footing poured and blocks placed to create the foundation to support the walls of the structure. Advantages include easy access to wiring, piping, and ductwork, making repairs and upgrades less expensive, and warmer floors due to the crawlspace being conditioned. Disadvantages include a higher risk of moisture, mold, and little to no protection from bad weather.
The Basement Foundation
A basement is a hole that is 8 feet or deeper that ends in a concrete slab. Basements are now built with poured concrete walls, which have eliminated common problems related to structural integrity and moisture saturation. Advantages include additional square footage at a lower cost, energy-efficient living quarters, and protection from storms. Disadvantages include the high cost to build.
It’s important to note that there are other types of home foundations beyond the three main options discussed here. However, slab, crawlspace, and basement foundations are the most commonly encountered types when buying a home. Each type has its own pros and cons, and it’s important to consider these factors along with your budget and personal preferences when making your decision.
Ultimately, it’s crucial to ensure that your chosen foundation can effectively support the structure above it and keep water and soil out to protect your home.
