The exterior waterproofing process includes digging the soil surrounding your house and repairing leaks with a powerful sealant. Indoor basement waterproofing systems are considered better and more effective in preventing damp basements. Depending on your budget and structural needs, each of these waterproofing methods has its advantages and disadvantages, but it will surely prevent your property from deteriorating even further. Exterior waterproofing, while more expensive, provides the most efficient water prevention.

Interior waterproofing is more affordable and easier to maintain in the long term. Waterproofing the basement from the inside costs less than outdoor waterproofing because it requires less work and fewer materials. In the long run, you'll save money with outdoor waterproofing because it's more efficient. When properly applied, I prefer waterproofing from the outside.

It keeps water out of the concrete, rather than penetrating into the inner waterproof layer. If it is allowed to freeze on the base, it could have cracks. Waterproofing the outside of the foundation is the best way to shore up the basement. Interior waterproofing can prevent water damage from worsening, but doing repairs on the outside corrects weaknesses right from the start.

This prevents water from entering the house, protects concrete or foundation stone from erosion, and prevents the foundation from crumbling. Indoor basement waterproofing systems are often installed as remedial solutions to clean and address leaks and floods that have already occurred. Usually, a trench opens inside the basement, parallel to the affected area. Then, a drainage system is installed, often a sump pump, to redirect water out of your house and away from it.

The trench is hermetically closed. This process will dry out the basement and prevent future water intrusions. Compared to exterior waterproofing systems, waterproofing the inside of the house is usually less expensive and is more commonly used after water has already entered the basement. Another important part of outdoor waterproofing includes a waterproof membrane, which is installed around the foundation of your house to seal moisture so that concrete does not absorb it, cracks and allows leaks.

After seeing the extensive excavation needed to waterproof from the outside of the basement, most homeowners opt for interior waterproofing options, such as an interior drainage system (IDS). Engineers have designed reliable waterproofing methods and made them available for you to choose from, and that means that regardless of how your basement was built, it can be waterproofed. But should you approach basement waterproofing from the outside or inside of your home? We have researched both methods of waterproofing to get the best answer for you.
