Houses in the Southwest are typically not built with basements due to the lack of water in the soil. The soil in most parts of the Southwest is dry and sandy, making it difficult to excavate and construct a basement. Here are some reasons why houses in the Southwest do not have basements:
The soil composition: The soil in the Southwest is typically dry and sandy. It is more difficult to excavate and construct a basement in this type of soil. In some cases, builders use a special type of concrete foundation known as a slab-on-grade rather than a traditional basement.
The water table: The water table, or the level at which groundwater is located beneath the surface, is generally lower in the Southwest compared to other regions of the country. This means that there is less moisture in the soil, and digging a basement would likely require more effort and expense.
The climate: The Southwest is known for its hot and dry climate, which means that moisture is not likely to accumulate in the soil. Without enough moisture, basements are not practical or necessary.
While there are some exceptions, such as homes in parts of New Mexico and Arizona that have basements, these are rare and typically only found in areas where the soil is more suitable for excavation. In general, homes in the Southwest are built with alternative foundations that are better suited to the dry, sandy soil and hot, dry climate.
