Insects, rodents, mold, musty odors, termites, and wood rot and are all symptoms of a wet crawlspace. These pesky issues can all be prevented with crawl space waterproofing. Here are five tips about crawl space waterproofing:

1.) All basement and crawlspace waterproofing starts with the external perimeter. How are the gutters and downspouts? Are they damaged or clogged? Are they dumping excess water directly next to the foundation? If this is happening, then you need to get that fixed first. This is your first line of defense when it comes to any waterproofing system. 

2.) Landscaping should also be sloped away from your house. All the exterior drainage should flow away from the foundation. Grading should never direct water toward the house. No matter what system you install if your grade is directing water toward the house, it will be in overloaded with unnecessary water.

3.) Inside the crawlspace you also need to install an interior drainage system. Many crawlspaces have dirt floors that need plastic liners. Before you install a liner you need to take care of the water problem. You will just create a nice water bed in the crawlspace if you don’t. 

4.) Make sure to fix any cracks in the foundation wall with crack injection materials. A crack is another way for water to penetrate the crawl space especially if you decide to seal a vented crawl space.

5.) If you have a dirt floor then you will most likely need to completely encapsulate the crawlspace. The vents are closed and a heavy liner is installed on the floor and the walls of the crawlspace to create a building envelope isolating the space from the ground and outside air. Then either a dehumidifier or conditioning system is installed to treat the air exchange as part of the home. The upper levels of the house and the crawl space where already experiencing air exchanges but with the crawl space encapsulation it will be healthier air.

If you have water in your crawlspace, it is a problem you can’t ignore. Even if you try to, if you ever want to sell your house then your home won’t pass a home inspection with a wet crawlspace. You will have to deal with it sometime so why not deal with it now and enjoy the benefits, too. Treating the crawlspace like a part of the rest of the house will result in better indoor air quality, lower energy bills and will eliminate all the issues like mold, mildew, rot, insects, and rodents that come with a wet crawl space.
