Water in the basement can result in mold issues and structural problems, damaging your possessions and the health of your family. Learning how to properly waterproof your basement prevents you from trying methods that will not work and could cause the problem to worsen.
Waterproofing involves several key steps, including an assessment, crack repairs, application of exterior waterproofing compounds, exterior drainage and the proper finishing techniques. Skip one of those steps and water will likely find a way in.
Steps to Waterproofing a Basement
Conduct a thorough assessment of the area, making note of any areas that display signs of leaks and seepage. Typically concrete foundation walls and flooring have cracks, although not all of these imperfections allow water to pass through. Try to assess the area at different times of the year, or at least during different weather patterns, to get a better idea of actual conditions.
Repair cracks and holes with proper exterior sealants to create a smooth, impenetrable envelope around your basement. The proper waterproofing compound or membrane will be applied over this surface, but crack and hole repair must be completed first to ensure optimum protection.
Dealing With Pressure
When water pressure from outside of your home results in seepage and leakage, interior sealants will be ineffective and will triple the mold and mildew. Specialized repairs must be done in order to counteract the pressure and keep the water out.
Exterior drainage at the base of the footing in addition to membranes and other waterproofing products must be applied to the outside of your foundation wall, providing additional protection against water pressure.
Talk to a professional contractor about how to waterproof your basement effectively. Most DIY products rarely do the trick and most of the time more extensive work is required to eliminate moisture and standing water in your home.
