One of the spaces you might overlook in your efforts to protect your home is the crawl space. When it rains, standing water can get into the space. It might not seem like a big deal, but if it happens frequently, you could face serious problems later. If your crawl space has a water issue, here is what you need to know.
Why Is Water in the Crawl Space Bad?
The crawl space might seem unimportant, but it is very important. When it comes to your crawl space, try to think of it as part of the home. When the space floods and has standing water, the structural integrity of the home's foundation can be weakened.
The water beneath your home could even cause damage to the floor joists. The longer the joists are exposed to the water, the more weakened they become. Your floor could literally collapse.
Even if the floor does not collapse and the foundation holds up, you still could be faced with mold problems. The mold can travel from your crawl space to adjacent moist areas. For most people, this is a health risk. If someone in your home has a breathing-related disorder, such as emphysema or asthma, the presence of mold could be especially harmful.
To protect your home, the crawl space needs to be waterproofed. Depending on several factors, you can choose to waterproof the home from the interior or exterior.
How Do You Waterproof the Crawl Space?
There are several steps you can take to protect the crawl space from water, but before you do any of those things, you need to have sump pump installation performed. The sump pump will help to drain water from the crawl space. If you do install the pump, make sure a battery backup is included. The sump pump will still work if the power goes out.
In addition to installing a sump pump, you need to ensure that the earth near your home is sloped away from it. Instead of the water building up and eventually flooding into your crawl space, it will flow away from the home.
The addition of a perimeter drain can also be useful. The drain will collect any groundwater that rises along the perimeter of the home and push it away from the foundation of the home. If you are installing the drain, make sure it has a filter sock to prevent soil buildup.
