A home's crawl space is an extra storage space for many homeowners, providing additional storage for their belongings and for food. Unfortunately, your crawl space can become subjected to moisture from the soil around your foundation and exterior groundwater sources nearby, causing the space to be rendered useless until you are able to protect it from outside water. Here are some methods to help you keep your basement crawl space dry and a good storage space for your possessions.
Block Interior Ground Moisture
One successful method to keep your basement crawl space dry is to block any exterior water from entering the space. You can complete this by hiring the installation of a vapor barrier over the interior walls and flooring of the crawlspace. All the seams and connecting junctions of the vapor barrier are sealed to make the space completely air tight.
By encapsulating any areas where water can normally enter through, you keep the interior space dry. Then, any water that collects behind the vapor barrier can run back into the soil. It is also recommended to use a dehumidifier inside the crawl space because it will be so air tight that there won't be enough ventilation to keep the air from becoming humid. As a side benefit, your home's energy efficiency will be increased once your crawl space is encapsulated. Talk to a basement and crawl space waterproofing professional to find out your options for remedying the moisture problems.
Divert Outside Ground Moisture
Ground water outside your crawl space can seep into your crawl space, especially when you live nearby a body of water, creek, or other high water table situation. Water naturally flows the path of least resistance, which can end up inside your crawl space walls and floor, especially if it is a dirt floor.
You can prevent water from entering your crawl space by installing an exterior French drain around the outside of your home's foundation surrounding the crawl space walls. You can hire a professional contractor to excavate the trench to an appropriate depth and install the layer of gravel below and above the perforated drain pipe, which collects any ground water to divert it away from your home. The drain pipe usually runs to a point away from your home where it deposits any collected water.
Also make sure your home's roof drainage gutters and downspouts are working properly to collect and divert water several feet away from your home and its foundation. Often, a roof downspout is left to dumps water directly onto the ground and soil around the foundation of your home, allowing the water to seep into the foundation and crawl space area inside. You can have a gutter and roof professional inspect and correct any deficiencies in your roof drainage to prevent moisture problems.
