House Foundation Types

Houses are generally categorized according to their foundation design. The type of foundation affects the kind of radon reduction system that will work best for your home.

Types of foundations include:

• Basement
• Slab-on-grade (concrete poured at ground level)
• Crawlspace (a shallow unfinished space under the first floor)

Some houses have more than one foundation type. For example, it is common to have a basement under part of the house and to have a slab-on-grade under the rest of the house. In these cases, it may be necessary to have to use a combination of radon reduction techniques.

Radon reduction systems are grouped by house foundation design. Find your type of foundation design and read about which radon reduction systems may be best suited for your house.
