"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

Basement Waterproofing questions, answered by experts

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.
