Do-it-yourself Basement Waterproofing

So you’re getting water in your basement. Well, I know a thing or two about this. I began my career when I was 19 years old jackhammering basement floors up and hauling the mud and concrete in and out of homes like yours. Today, I have over 45 years experience in basement waterproofing. I’m going to tell you everything you need to know about DIY basement waterproofing.

Basement waterproofing always starts outside your home.

While a variety of conditions can cause a wet basement, one of the main culprits is roof water runoff and pooling surface water around your foundation after a storm or when the snow starts to melt. Take a walk around your home and look for any low areas that collect water. Then, fill them in with dirt, grading it always from your foundation. Also, check your service walks. They should tilt away from the foundation.

Are your gutters free of leaves and debris that could cause rainwater to spill over the side of the gutter? Are your downspout extensions connected? Your downspouts should carrying the water at least 8 feet out from your foundation. This a critical preventive step many homeowners over look.

Lastly, check your window wells. You want to clean them out regularly, removing leaves and debris. Another helpful tip is digging your window wells down 12 inches below the window, then add a layer of stone to help with drainage. Many basements can be dried up with these simple preventative steps.

Don’t make this #1 do-it-yourself mistake!

The #1 DIY basement waterproofing mistake is trying to stop or hold back seeping water in your basement with waterproofing paints or hydraulic cement. Paints, patch-its or plug-its never work longterm and cause hydrostatic pressure to build to dangerous levels in your basement, resulting in your buckling floor or foundation wall cracks.

In contrast, a professional waterproofer taps into and relieves hydrostatic pressure when installing a basement waterproofing system to collect and channel water.

Hydrostatic pressure is what builds up around your foundation and pushes water seepage into your basement. Water soaks down into the ground just outside the walls and starts building up its muscle 1 inch at a time, until it’s built up 2 or 3 feet high on your walls. Height is what gives water its strength, better known in the industry as hydrostatic pressure. The water is strongest at its lowest point, which is down around your basement’s floor. Hydrostatic pressure is what forces water into your basement through the seam where your floor and walls meet.
