How to Keep Your Basement from Flooding: Important Waterproofing Tips


The problem of leaking walls and seepage in basements are pretty common in many households. Usually, people get their basements waterproofed beforehand but even then, problems occur because the job wasn’t done well. There are many reasons why leakages happen, but you need to find a way to fix and waterproof your basement. Most people do the job themselves, but you can hire someone to do basement waterproofing if you find it too difficult.

If you plan to waterproof your basement yourself, there are a few things you should know about. The following points will make your waterproofing job easier and will give you excellent results:

1. Repair the Holes and Cracks – This step has to start before the waterproofing project. Patch the cracks and holes and clean them out before applying the waterproofing mix on your walls. The cracks and bigger holes can be filled with latex cement, which you can easily get from any hardware stores. Use a putty knife and smooth the layer after you fill up the cracks. You can chip broken concrete pieces if the hole appears to be too large and then fill it with mortar. Make sure there are no air pockets when you fill it and cover it perfectly.

2. Prepare the Basement Walls for the Waterproof Mix – You can start your waterproofing project once all your cracks and holes have been filled up. Get a waterproof mix and follow all the directions very carefully when you mix it. If your wall has been painted, you need to get a waterproof mix that sticks to paint. Otherwise, you have to sand off all the basement walls’ paint before you apply the waterproof mix on them. You can also take the help of a wire brush for removing the paint.

It is usual for the waterproof mix to stick better when the walls are slightly damp. So, use a sprayer to dampen the walls but make sure that there isn’t any dripping water. Just spray a thin layer of water on the walls to wet them a bit.

3. Waterproof the Floors and the Basement Walls – Always use a stiff brush and practice a circular motion for application of waterproof mix on the walls. You have to be careful to cover every little pore on the wall of the basement. Usually, at the wall bottom, the pressure of water is more and this should be your target area as leaks could mostly occur here. Start from the bottom and then go to the top. Apply as many layers as needed to make sure everything is covered properly.

After the coating dries a bit, spray a gentle coat of water and leave it for a day to dry. After that, apply a fresh coat and repeat the process. The same technique should be used for the floor.

Now you know the basics of basement waterproofing.  Don’t store your important stuff in the basement before waterproofing it. It could ruin all your things. Start your waterproofing project and after it is finished, you can move all your spare stuff in the basement and not worry about leaks and seepage again.
