Q: Is a vapor barrier required in a crawl space?

• <div><p>In nearly all cases, you are required to install a vapor barrier in your crawl space.

Even if a vapor barrier is not legally required, it is often a good idea to <a href="https://www.angi.com/articles/4-steps-protect-your-crawl-space.htm">keep your crawl space dry</a>.</p></div>

Q: Should you cover the dirt in a crawl space?

• <div><p>Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there&rsquo;s a lower chance of dust mites breeding and causing allergic reactions in your home.</p></div>

Q: What materials can stop a flood?

• <div><p>The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged. </p></div>
