Interior & Exterior Drainage Systems for Virginia Homes

Basement Masters Waterproofing can help you protect your biggest investment, your home. Basement waterproofing should be done right and provide a lasting solution. Exterior wall waterproofing can’t prevent water from moving deep below your foundation walls. This water can creep through your basement and/or crawl space floor. If you have serious water problems in your basement or affecting your foundation, you may have to have both exterior and interior waterproofing systems installed in your home. Doing just an interior drainage system is not full waterproofing. Interior drainage systems are water management agents that reduce excess water from around and below your foundation. The exterior drainage system is what will continue to direct water away from your home.

Moisture is conveyed from the outside of your house to your basement interior by four primary methods:

  • The first one is water flow. As you know, water takes the trail of least resistance. If this is the pathway to your basement, then that is where the water will go.
  • Second, capillary action. Concrete is a porous material. Think of capillary action being like a wick. As concrete is saturated in water, it becomes completely drenched and then disperses moisture and water vapor inside your home.
  • The next method is vapor diffusion. Vapor diffusion is much like capillary suction, apart from water vapor.
  • Lastly, air movement. Every time that a door or window is opened you are bringing air into your home and pulling air from the basement to the upper existing levels. This is known as the stack effect.

Did you know that on average, about 50% of the air we breathe in our homes comes from the basement? This is why our exterior or interior drainage systems are so incredibly important for the future safety of your home and family. Call us today to learn more about water drainage options for the Northern Virginia area.
