If you have a basement, you may experience the frustration of water intrusion. A leaky basement can be frustrating and even dangerous. Installing a drainage system allows water to be directed away from the basement during a rainstorm or other conditions. Basement floors and walls stay dry, making the environment safer and healthier. Learn more about the features and installation process for a closed basement drainage system by reading below.
Step 1: The cold joint is the point where the basement wall and floor meet. This natural seam is an easy target for water trying to penetrate the foundation of the home. With a closed basement drainage system, a special gasket or flange and a wall vapor barrier are installed to create a virtually airtight seal that prevents soil gasses and ground humidity from entering the basement. The vapor barrier should be sealed at the top of the wall. Forty percent of the air breathed within the home comes from the basement. This makes a tight seal at the wall and seal joint the healthy way to keep the basement dry.
Step 2: The drainage system is located beneath the basement floor at a location extending from the cold joint. Anything that is behind the seal is guided toward the drainage system and into a basement sump pump. The water issue is resolved in a way that does not create other problems like introducing high humidity levels or soil-based radon gas into living areas. Water that enters the basement area will not stagnate or travel through an open channel so there will not be any odors or smells.
Step 3: The drainage channel is installed in a shallow trench dug in the basement floor. This directs the water into the sump pump, which should be installed in a pit featuring an airtight linger. Pump and liner mounts should not undermine the integrity of the basement foundation. The pump should be installed to automatically turn on and off based on water level within the pit.
