What is a Crawl Space?
A crawl space is a type of basement usually not high enough to stand up in. The height may be as little as one foot and the surface is often rocks or soil. Older homes in certain areas, where basements are rare, have high foundations with crawl spaces that allow cooling air to circulate throughout the home. Over 40% of the air on the first floor of a home comes from the basement or crawl space. Moisture and unsafe air can enter the home that way, causing potential health hazards. Waterproofing and encapsulation are essential to a healthy home.
Crawl Spaces Encapsulation
Installing a complete vapor barrier provides the crawl space with a moisture protection layer to protect the structure from the negative effects of moisture such as mold, floor failure, increased electricity costs, odors, insects, and dust mites. High relative humidity and moisture can have major health effects, causing or worsening asthma, hay fever, allergies and other respiratory conditions.
Crawl Spaces Protect Your Home Against:
- Condensational moisture
- High levels of humidity
- Ground moisture vapors
- Moisture intrusion from outside of the foundation walls
Crawl Space Waterproofing:
Building scientists and other building experts recommend that crawlspaces be sealed or encapsulated. This upgrade makes buildings more energy efficient and eliminates problems with moisture, mold and pests in the crawl space. Some crawlspaces also need to be waterproofed.
Crawl Space Moisture Control:
A damp, dirty crawlspace is an eyesore. But the presence of mold, wood rot, and pest in the crawlspace means you have more significant problems. Moisture in a crawlspace will attract mold as well as insect and animal pests.
It’s wise to be concerned about foundation walls that have bowed, cracked or tilted, or slabs that have sunk shifted or heaved. When a foundation has structural damage, it’s a sure bet that the problem won’t go away. In fact, it usually worsens over time.

Does water somehow find its way into your basement? An interior perimeter drainage system addresses hydrostatic pressure – that is, the pressure of groundwater forcing its way through the basement walls or foundation.
Sump Pump Systems
A crawlspace needs a sump pump system that is able to handle the storm water that comes in and around the foundation of the home. Depending on the size basement, you may need two sump pump systems to keep up with the job. Ensure you have a battery back-up incase you lose power in a storm because you want your sump pump to continue to work without it.
If you’ve experienced leaking walls or seepage through the floors or cracks in your home’s foundation, you need a system that’s going to keep your basement dry, all the time.
