Basement Waterproofing questions, answered by experts

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.
