Pros of a Slab Foundation
- Better for moist climates as it prevents mold growth in the home
- Less subjectable to insects and pests
- More affordable
- Faster to construct
- Sturdy and strong since slabs are 24 inches thick
- Requires less maintenance
- More energy efficient since it insulates the flooring of your house by preventing cold air from flowing underneath, unlike crawl space foundations
- Durable—it can last for 50 years or more
- Comfortable to walk on
Cons of a Slab Foundation
- Cracks easily with shifting soil
- Floods more easily
- Tree roots can damage it. Homeowners are advised not to plant trees too close to the foundation—no less than 50 feet away
- Repairs can be more expensive
- No basement storage
- Plumbing fixtures and electrical wiring are embedded in the concrete, and they’re not flexible if you want to do any future renovations
