Sump pumps? Footer tiles? Interior French Drains? What are they and which is best?

A proper drainage system is vital to any crawl space encapsulation project. Most crawl spaces in central Indiana contain sump pumps. A sump pump is a pump installed in a basin/pit that helps remove the natural ground water that typically begins to flow during heavy rain storms. While these can be effective at this type of water removal, they are not the entire solution.

Footer tiles are pipes with holes installed into them used to catch water along the exterior foundation of your home. These pipes are then typically directed away from the home to help keep pressure(From Ground Water) off of your foundation. These are very efficient and work well, however can be installed incorrectly or less effective over time. Installing an exterior footer tile after the fact can be very difficult due to landscaping, potential concrete, and weather conditions. 

Interior French Drain

Interior French Drains are very similar to footer tiles, however are installed on the inside of the crawl space. Trenches are dug along the inside of the foundation bottom and then fabric, gravel, and perforated pipe is installed to control any water that begins to flood the crawl space. These pipes are then channeled to the sump pump inside the home. This is one of the most effective and efficient method to rid water of a crawl space.

Vented versus Closed Crawl Spaces

June 05 2020 by Mitch Sutherland

        Today we are going to write about the debate of open versus closed(Encapsulated) crawl spaces. Homes have been built with crawl spaces for years, and this also includes crawl space vents. In fact, homes are still built using crawlspaces and vents today! Initially crawl space vents were thought to dry out the crawl space and provide good air exchange. This in theory would have prevented stagnant air and mold growth. However, society began to realize crawl space vents by themselves was not enough. Crawl space vent fans began to slowly hit the market to aid in air exchange even more. Slowly but surely this has proven not work very well at prevent moisture/mold either. 

      So, what should you do with your vents then? Properly seal them off. This essentially is what encapsulation is. We close off the vents, and air seal the entire crawl space. This gives us the ability to properly condition the air inside the crawl space. With the use of spray foam, insulation, proper vapor barrier sealing, and a dehumidifier your crawl space can combat high levels of humidity and temperature changes. This is highly beneficial due to the fact as much as 50 percent of the air you breathe on the first floor of your home comes from the crawl space. 

        In closing, by controlling these factors, your crawlspace will be more energy efficient, have better air quality, and will remain structurally sound for years to come. Below is a great resource study performed proving the benefits of encapsulating a crawl space versus non encapsulated crawlspaces.
