When it comes to waterproofing crawl spaces, basements and foundations, there are several mistakes that people make. One mistake is not having a check valve on the sump pump. This is necessary in order to prevent water from flowing back into the basement after the pump has shut off. Another essential element of waterproofing is making sure that your sump pump has a basin. Without this, the pump may become clogged and not be able to adequately remove water from the area.

Another mistake that people make is not including a vapor barrier on the walls when waterproofing. This will help reduce moisture levels in the air and ensure that no water seeps through the walls into your basement or crawl space.

It is important to make sure that you have a minimum of 15ft of discharge line for your sump pump. This will ensure that the water can be directed far enough away from the home to prevent any flooding or leakage. If you are using a French drain, then you may need more room in order to ensure that it can be filled with an aggregate.

Painting the walls of your crawl space is not always a good idea as this will seal in moisture and create a breeding ground for mold and mildew. It may seem like a good idea at the time, but you are actually doing more harm than good by painting your basement or crawl space walls.

By avoiding these common mistakes, you can ensure that your waterproofing efforts are effective and will protect your home from potential water damage. Take the time to research and understand all of the steps involved in waterproofing to ensure that everything is done correctly. This will help save you time, money, and a lot of headaches in the long run.

Now that you know more about mistakes to avoid when waterproofing crawl spaces and basements, you can be better prepared for your upcoming project and make sure it is done correctly the first time. Good luck!
