Waterproofing Basement Walls

The basement, by definition, is below ground level, meaning it is awfully vulnerable to flooding and excess moisture coming through porous walls and floors. Moisture can lead to mold and mildew growth as well as water damage. Fortunately, there are ways to protect your basement against these forces of nature. In this article brought to you by Tidal Wave Restoration, we will go over some of these methods to waterproof the basement. If the damage has been done and you need water damage removal or water damage restoration, then call Tidal Wave Restoration for reliable service in Metro Atlanta and surround cities.

Causes of Wet Basement

Before we get to waterproofing the basement, it’s important to know about some of the reasons why the basement gets wet in the first place:

  • Poor Grading: When your home was built, the ground around the foundation should have been graded so that it slopes AWAY from the house and not towards it. This naturally drains rainwater and floodwater away from the foundation and basement.
  • Cracks: The basement and foundation CAN crack and allow water to enter, especially if the house settles and soil shifts. Plumbing leaks and slab leaks can also cause damage to the foundation.
  • Poor Drainage: Properly installed gutters, downspouts, and drains will direct rainwater away from the property. Poor drainage can lead to puddling of water around the building.
  • Unsecured Entry: Windows and doors that are partly open or not properly sealed will allow water and moisture to enter the basement.
  • Condensation: When warm, humid air meets the coolness of a basement, the result is usually condensation. In severe cases, this condensation can lead to excess moisture.

Protecting the Basement

Waterproofing your basement can save you from mold and mildew growth, damaged appliances and electronics, water damage to your basement, and more. Here are some steps to waterproofing your basement:

  • Drain the basement of all water and moisture. You can employ your sump pump and/or dehumidifier if available.
  • Clean up the area and remove existing coatings on the surface, wall, or floor. Wash off dirt and dust with warm water and dish soap, and tackle mold and mildew with a bleach solution (1 cup bleach to every gallon of water). Never mix bleach and ammonia!
  • Remove efflorescence, or the crystal-like deposits on the surface of basement walls. Removing that salt residue helps ensure the waterproof paint will adhere.
  • Plug all holes in the walls and floors with hydraulic cement and use a trowel to smoothen it before it sets.
  • Use silicone caulk to seal windows and doors of the basement.
  • Apply waterproof coating using a nap roller, nylon bristle brush, or concrete sealer. Apply at least two coats according to instructions on the product.
