Waterproofing a basement from the inside is usually the best option for most homes, mainly because it is more cost-effective and less harmful than digging outside. An interior basement waterproofing system can effectively manage water below ground by removing groundwater before it touches the ground. Some systems sold by large franchises manage water almost at ground level, making it impossible to keep moisture out and keep walls and floors dry. Make sure you have a system that manages water in the proper location under the floor.
The beauty of all this is that you don't lose anything from your outdoor landscaping with an outdoor excavation project. Most interior waterproofing systems are installed in 2 or 3 days when done correctly. Do waterproof coatings work? The short answer is yes. We have used waterproof coatings in basements with excellent results.
But careful preparation work is essential; the coating cannot stop water unless it can firmly adhere to the masonry. And we always recommend that you first re-qualify the landscape and add or update downspouts and gutters. Here's how to cure a wet basement once and for all. Interior waterproofing methods, such as waterproof sealants, also help keep moisture levels low and prevent condensation.
These coatings can be placed on the walls and floors of the basement creating a waterproof barrier. While these interior sealants are an important step in the overall waterproofing process, they do not address the underlying issues that cause moisture. The biggest problems are usually found on the outside. The return on investment will depend on the size of your home, the area in which you live and the amount of waterproofing.
But it's a valuable home improvement that's worth the initial investment. The duration of the waterproofing depends on several factors, including the amount of waterproofing product used, the weather and the severity of the initial damage. A superficial DIY interior repair and an expensive and short-lived exterior waterproofing are not comparable to an interior basement waterproofing system. Exterior waterproofing requires expensive and complicated procedures compared to internal basement waterproofing.
Exterior waterproofing involves digging around the house to the full depth of the foundation walls, then installing a waterproof layer or membrane covered by drainage panels.
