  2. Definition • the first piece of a home to be constructed and creates a base for the rest of a home's components. There are three types of foundations that are commonly used in the U.S.: full-height basement, crawlspace, and slab on grade.

  3. Full Height Basement • an accessible space between the soil and the bottom of the first floor of a home. It usually has more headroom than a crawlspace. Used in cold climates due to frost.

  4. Crawlspace • an accessible space with limited headroom, typically between the soil and the bottom of the first floor of a home.

  5. Slab-on-Grade • a type of foundation consisting of a structural concrete slab poured directly on the grade.

  6. Important Information • Frost Line 48” in NYS

  7. Building a Foundation Usually constructed out of poured concrete. Other options: • Concrete Masonry Units • Insulated Concrete Forms

  8. Concrete Masonry Units • CMU’s- (Cinder blocks) Hollow concrete blocks connected with mortar to form walls

  9. Insulated Concrete Forms • ICF’s are rigid foam forms which concrete is poured into. Once concrete is cured, forms can be kept in place for insulation purposes.
