Q: Why does my basement leak after heavy rain?

• <div><p>If your basement often leaks after heavy rain, it&rsquo;s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home&rsquo;s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.</p></div>

Q: Is it okay for a crawl space to be wet?

• <div><p>No, you don&rsquo;t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage.

Q: Should you put plastic over insulation in basement walls?

• <div><p>A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.</p></div>

Q: What causes a basement wall to bow?

• <div><p>External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure&mdash;these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent. </p></div>

Q: How do I prevent foundation cracks?

• <div><p>The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.</p></div>
