Q: Is it unhealthy or dangerous to live in a damp basement?

• <div><p>Yes, it is generally unhealthy and can be dangerous to live in a damp basement.

Q: How do you make a homemade water barrier?

• <div><p>Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they&rsquo;re tightly laid on top of each other, creating the effect of a firm wall against accumulating water. </p></div>

Q: Do services include foundation recommendations?

• <div><p>Yes, engineers assess soil load-bearing capacity and provide construction guidelines.</p></div>
