Why Is My Crawl Space Leaking?

Your crawl space can take on unwanted moisture for a variety of reasons. Hydrostatic pressure is the primary force behind crawl space damage, as it can force your structural supports, walls, and other materials to crack and leak. 

• The Forces Behind Your Leaking Crawl Space 

It isn’t just hydrostatic pressure, however, that can cause your crawl space to start taking on unwanted moisture. Some of the other common causes of crawl space leaks:  

• Errors during home construction 
• Errors during window installation 
• Freezes 
• Pipe damage 
• HVAC system damage 

The grading of the landscaping around your home, too, may bring more water toward your perimeter than is safe. You can work with area contractors to determine where your home sits in your yard, with the grade in mind, and adjust your landscaping accordingly. 

• The Benefits of Additional Home Waterproofing Measures 

Again, an air control fan system and a vapor barrier will both help you keep unwanted moisture out of your crawl space, but only after you’ve invested in the repairs your home needs. There are additional waterproofing measures that you can stack with both a vapor barrier and an air control fan system if you want to double down on your home waterproofing techniques. These can include:  

• Interior sump pumps 
• Interior drains 
• Full space encapsulations 
• Dehumidifiers 

Note, of course, that no home waterproofing measure is going to last you forever. If you think that any leaks you’re seeing in your crawl space may relate to the state of your foundation, you can invest in piering or underpinning procedures and keep your home water-free for longer.
