Basement Waterproofing questions, answered by experts

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.
