Types of home foundations are to know when looking at buying a home. Different types of foundations are found in different parts of the country, different soil types, different slope types and different ages of homes.
Basement Foundation
Full basement foundations are deep, allowing for conversion into living space. They’re the most expensive of all the types of foundations, but the biggest advantage is all the extra living space that a basement provides. The drawback can be water problems (drainage, mold, mildew), so ask about that when touring a home as a buyer.
Crawlspace Foundation
This foundation is only about four feet or less in height. It’s typically built above the ground, or on uneven ground. Pay particular attention to drainage. Crawlspaces give good airflow beneath the house, to prevent moisture. Too short to be converted into living space, they can be used for storage. Crawlspace foundations are less expensive than full basements.
Pier and Beam Foundation
These resemble crawlspaces but uses a system of concrete or wood piers that support a grid of beams that the house sits upon. They’re used in areas prone to flooding or storm water surges.
Concrete Slab Foundation
This is exactly how it sounds: A solid concrete slab that sits on the ground. These are most common in climates that don’t experience a lot of freezing and thawing, as that would lead to cracks and shifts in the foundation. This is one of the most economical choices for a foundation.
