Q: Why are houses built with crawl spaces?

• <div><p>The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They&rsquo;re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they&rsquo;re at less of a risk of freezing.</p></div>

Q: Is a structural engineer the same as a builder?
