Basement Waterproofing questions, answered by experts

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.
