Crawl space moisture can create a hazardous environment. Air that circulates throughout your home, starts from the bottom and rises. This means that air in your crawl space is filtered through your home. If you or someone in your home suffers from allergies or asthma it may be time to waterproof your crawl space.
Is There Water in Your Crawlspace?
Signs of water in your crawlspace:
hardwood floors buckling
strong odor coming in home
cracks in sheetrock
mold growing in home
Crawl Space Waterproofing – How its done:
First, the inside perimeter of the crawlspace is hand dug creating a trench.
After creating the trench, a hole is dug for the sump basin to sit. The trench is then grated towards a 15-gallon sump basin.
EZ Flow piping is installed in the trench and connected to the basin. Once the EZ Flow has been installed in the trench, it is then covered with original soil.
A sump pump with PVC discharge piping is installed into the sump basin to pump water outside of the crawlspace and away from the structure.
A 10 – mil white moisture barrier is recommended to complete the crawlspace waterproofing installation.
After the Affordable Foundation and Home Repairs team completes the crawlspace waterproofing system on your home, you can rest assured knowing that your crawlspace is protected from outside elements entering your home.
Why Do I have water in my crawl space?
Soil absorbs and retains moisture, thus causing moisture to reside on the surface and form puddles.
The main causes for a wet/damp crawl space are:
Porous foundation blocks
Water that pools in your crawl space causes higher humidity in the crawl space atmosphere. Mold, wood rot, and fungus thrive in wet/damp crawl spaces. Pests such as termites, rats, mice, spiders, snakes and other rodents also thrive in damp or wet crawl spaces. A wet/damp crawl space provides a cool place for animals and fungi to remain safe and also provide the nutrients they need from water.
Why Should I Waterproof My Crawl Space?
Below are some of the key benefits to crawlspace waterproofing:
Added Selling Feature
Home buyers are more likely to buy a home that has a waterproofed crawl space over a home that has not.
Lower Energy Costs
Crawl space waterproofing results in a 15-20% savings on heating and cooling each year.
Better Air Quality
Crawl space waterproofing prevents mold growth and other allergens from growing in your crawl space. Over 50% of the air you breathe comes through your crawl space. Make sure your crawl space and family are healthy by waterproofing your crawl space.
How Do I Get Rid of Crawl Space Water?
Proper Ways to Repair Crawl Space
Whether you’re experiencing issues with water or hoping to prevent problematic water issues in your crawlspace, you’ve come to the right place. First, let’s understand how a crawl space home is constructed. To begin, a large hole is dug in order to prepare the area for footings and the blocks to be installed. Once the footings and block or concrete walls are in place, some homes have a drainage pipe with gravel is installed around the outside perimeter of the wall in attempt to prevent water from entering the crawlspace. The pipe is to carry the water away from the structure. The area is then backfilled with the original soil and the home can be completed. Although the soil is compacted as much as possible during the construction of the home, it is not fully returned to its original compaction, therefore, causing loose soil around the structure. The less compacted soil causes water to seep into the soil, surrounding the foundation. Over time the previously installed piping and gravel become clogged. After precipitation the water table rises creating hydrostatic pressure against the crawlspace walls. To relive this pressure, the water begins to penetrate the crawlspace around the foundation seams and through the porous crawlspace block walls. Affordable Foundation and Home Repairs offers a permanent solution to your crawlspace waterproofing needs.
Improper Ways to Repair Crawl Space
- Installing vapor barrier alone – Installing a cheap, thin, plastic that covers the ground in your crawl space is not effective. Although it can help reduce humidity from the ground of the crawl space, it does not reduce the humidity that is brought in from the crawl space vents, thus, still allowing exterior air to flow.
- Poor Waterproofing – When dealing with a wet/damp crawl space, a homeowner should ensure that the crawl space has proper systems installed, such as crawl space waterproofing.
- Improper Mold Removal – Mold typically inhibits crawl spaces that contain moisture. To ensure a healthy crawl space, mold should be properly removed to ensure that it will not return.
- Installing a dehumidifier alone – When adding a dehumidifier to a crawl space, the home owner should be aware of crawl space vents and vapor barriers. Crawl space vents allow exterior humid air to be filtered throughout the crawl space. Blocks and soil retain water, therefore, without properly installed vapor barrier, in addition to sealed crawl space vents, adding a dehumidifier will not be effective.
