Two Kinds of Foundations:

There are two kinds of foundations found on homes in the DFW area: Pier-and-Beam, and Slab. Mostly found in homes built in the 1960's or earlier, a pier-and-beam foundation is comprised of footings (or piers) driven into the ground and secured by concrete bases, and beams that connect the piers. You can access a pier-and-beam foundation through the crawlspace under the house.

 

Homes built after 1970 most commonly have a  concrete slab foundation, or a “slab-on-grade” foundation.  A thick layer of concrete is laid directly on the ground with steel tension rods going through it for extra support.
