Why You Need a Crawl Space Moisture Barriers

If you have an existing crawl space and have noticed that the moisture level is starting to get pretty bad, you might want to consider a crawl space moisture barrier. Not only will it help stop water from entering your home through the cracks in the crawl space floor and walls, but it will also keep dampness and condensation from accumulating in the interior of your home in the main living areas. In this article, we’ll discuss the benefits of sealing your crawl space with a moisture barrier, what material to use, and how to install a barrier in your crawl space. After reading this article, you should be able to select a moisture barrier solution that will best protect your home and possessions. You should also have enough confidence in your ability to apply and install a barrier that will keep your home in good condition.

Two kinds of crawl space moisture barrier systems are available: mechanical and thermal. Mechanical vapor barriers are composed of a solid plastic sheet and are installed above the soil beneath the existing footer drains, foundation walls, and around exterior pipes, ductwork, and showers. Mechanical vapor barriers are a popular choice because they are simple to install with no visible structure on the surface of your foundation. However, the relative humidity of your crawl space will still be present in the gaps between the vapor barriers.

Another type of crawl space moisture barrier is the rigid thermal barrier. Rigid thermal barriers are installed between the soil and the interior concrete slab on the outside of the house. Rigid thermal barriers do not offer the protection that the rigid silicone moisture-barriers do, because the silicone molecules are too large to penetrate through the Earth’s surface. Instead, the rigid thermal barrier acts as a sort of “shelter island” for moisture, allowing it to be removed from the crawl spaces without damaging the surface underneath.

A final type of crawl space moisture barrier is the space water seal. This system is used around the perimeter drain of your home, between the exterior wall and the basement, or between the interior wall and the outside perimeter drain. Space water seal systems are effective because they prevent the evaporation of moisture from the soil surrounding the foundation, preventing water from leaking into your crawl space. They also provide a layer of insulation against the outdoor temperatures.

You might also consider a crawl space vapor barrier from the inside. When the walls surrounding your crawl space are constructed with flat roofs, there is little air movement between the walls. Consequently, condensation often forms on the interior walls and on windows and doors. A vapor barrier will prevent this buildup by reducing the amount of air movement.

There are many materials on the market that are recognized for being effective moisture barriers. Some of the most popular options include concrete mixes, polystyrene, vinyl sheets, and polyurethane grills. There is also a polyvinyl chlorine (PVC) product on the market that can be installed as a crawl space moisture barrier. This product is made from a plastic material that is durable, lightweight, and resistant to moisture.

Regardless of the material you choose, remember that vapor barriers are quite effective at stopping moisture from reaching your home. However, these systems can be very expensive. If you decide to install a barrier but would like additional options for controlling moisture, you can consider using a commercial grade water control system. These systems include a spray foam liner, which is applied to your walls and other penetrations. Spray foam has been proven to be effective in reducing moisture by up to 40 percent.

For basement and crawl space dirt and grime buildup, there are a number of solutions available. One of the most effective is the use of pre-fabricated liners. A pre-fabricated liner is available in sheet or tile form and is designed to resist moisture and protect against seepage and condensation. Many basement waterproofing companies offer this service as part of a complete basement remodeling project. Another option is to contact a reputable foundation waterproofing company. Many foundation waterproofing companies will come out to your house and evaluate your foundation walls and assess the situation.
