What Is a Crawlspace Moisture Barrier?

A moisture barrier, also known as a vapor barrier, is a heavy-duty tarp made from materials like polyethylene. The barrier is installed across the soil in your crawlspace, creating a protective layer that prevents moisture from escaping into the air above. By encapsulating the crawlspace, the barrier reduces humidity levels and minimizes the risks associated with damp conditions.

In addition to controlling moisture, a vapor barrier transforms the crawlspace into a more sanitary and usable area. It prevents technicians and plumbers from crawling through mud and allows homeowners to use the space for storage. For homes with a history of rodent activity, the barrier covers droppings and other waste, reducing exposure to harmful bacteria while allowing the waste to break down naturally into the soil.

Addressing Standing Water

Before installing a moisture barrier, it’s important to address any standing water in the crawlspace. Pooling water often stems from issues like poor drainage, plumbing leaks, or water infiltration during heavy rains. This water must be removed to prevent ongoing damage.

Depending on the source of the water, different solutions may be required. French drains are a popular choice for redirecting water away from the crawlspace. These systems use perforated pipes buried in gravel to channel water into a designated area. In cases where water needs to be actively removed, a sump pump may be installed. The pump collects water in a pit and directs it out of the crawlspace, keeping the area dry and ready for barrier installation.

Benefits of Crawlspace Moisture Barriers

Installing a moisture barrier offers several benefits that protect your home and improve your quality of life. By reducing moisture levels, the barrier helps preserve the structural integrity of your home’s foundation, preventing costly repairs in the future. It also creates an environment that deters pests, mold, and fungi, contributing to a healthier home.

A vapor barrier improves energy efficiency by reducing the load on your HVAC system. When crawlspaces are humid, warm air rises into the home, forcing air conditioners to work harder. By controlling moisture levels, the barrier keeps your home cooler in the summer and reduces energy bills.

Installation Process

The process of installing a crawlspace moisture barrier begins with a thorough inspection. Our team assesses the condition of the crawlspace, identifying issues like standing water, damaged insulation, or pest infestations. Once the space is cleared of debris and any necessary repairs are completed, the moisture barrier is installed.

The barrier is carefully laid across the entire surface of the crawlspace, with seams tightly sealed to create a continuous layer of protection. In cases where walls contribute to moisture infiltration, the barrier may extend partially up the walls for additional coverage. For homes with ongoing water infiltration risks, French drains or sump pumps may be integrated into the system.

Our goal is to create a crawlspace environment that protects your home from moisture while making the space more functional and sanitary.

Long-Term Maintenance

While a crawlspace moisture barrier provides lasting benefits, periodic maintenance helps maintain its effectiveness. Over time, barriers may become damaged from wear or pests, requiring minor repairs to keep the space properly sealed. Regular inspections also help identify new issues, such as leaks or drainage problems, before they lead to significant damage.
