What are the 3 types of foundations?
Foundation types vary, but likely your house or home’s addition does or will have one of these three foundations: full or daylight basement, crawlspace, or concrete slab-on-grade.
Is slab or raised foundation better?
If the building site has problematic soil, such as expansive clays, a raised floor foundation would perform much better than slab, as slab would most likely crack on this type of soil. A slab foundation is easier to construct when the grade of the build site is very low, meaning that there is little to no slope.
What house foundation lasts the longest?
The longest life expectancy for slate, iron, and clay / concrete roofs is 50 years or more. Timber shake roofs, go 30 years, cement fiber shingles last 25 years, asphalt shingles give up at 20 years.
Is a crawl space or slab better?
Slabs resist moisture but crack more easily when soil shifts. Crawl spaces work better on sloped properties but cost more. Slabs provide more durability, while crawl spaces hold up better in earthquake- and flood-prone areas.
How deep should a home foundation be?
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.
What is the cheapest house foundation?
If you’re building a home, a concrete slab makes sense because of its low cost. It’s the cheapest option available, and, comparatively speaking, it’s the quickest solution. The right crew can lay a concrete slab foundation in a short period of time, and the drying process doesn’t take much longer.

If you’re dry, choose a liquid, stick, or hydrating powder foundation. If your skin is oily, use oil-free liquid or powder foundation.
How do I know my foundation type?

What are the different foundation types?
There are five main foundation types and a handful of important variations. Basement Foundation. Crawlspace Stem Walls. Concrete Slab Foundations. Wood Foundations. Pier and Beam Foundations.
What is wrong with a slab foundation?
One of the most significant potential disadvantages is if the slab cracks. This can substantially compromise the structural integrity of the house and be difficult and expensive to repair. Among the factors that can result in a slab cracking are tree roots, soil displacement, earthquakes, or frozen ground.
Are raised foundations better?
Raised foundations are good because if you have a problem with plumbing or electrical you can crawl under the house and fix it, they aren’t encased in cement as above. If an earthquake or settling takes the level out of the house you can fairly simply level it. Much cheaper than re-pouring part of your slab.
Is block foundation better than concrete?
Poured concrete wall foundations are arguably stronger than cinder blocks. It is faster and more efficient to construct a poured wall but can be expensive if the cement plant is far away.

Is a basement better than a crawl space?
Additionally, basements have a higher clearance than crawl spaces, and are thus much better suited to be livable space in the home. Knowing the difference between crawl spaces vs. basements is helpful, but you may also be wondering about the purpose of each of these structural elements.
What is the difference between crawlspace and slab foundation?
A slab foundation is a raised slab that the house is built on top of. In comparison, a crawl space foundation has exterior concrete walls (and sometimes interior support walls) that elevate the house 18 inches or more above grade, creating an accessible area beneath the house used for plumbing and wiring.
