Tips & Guides on Waterproofing your Basement

A flooded basement can be a nightmare, but even small amounts of water getting in through cracks in your wall, basement window, or foundation can bring a list of scary problems, including mold, musty odors, damaged walls, damaged carpets. Discover what it takes to waterproof your basement with our easy basement waterproofing tips:

Check Your Drainage around your home.

When rain has nowhere to go but into your house, you’re going to have a problem! Proper drainage is KEY to waterproofing your basement. Make sure that your foundation is not the lowest point around your house.

Seal Your Cracks

Fill in the cracks and crevices in your foundation walls with concrete sealers to prevent leaks. Check the seams around your basement window regularly to be sure the sealant is intact.

Inspect Your Gutters

Basement floods start at your roof. Check your gutters for overflowing areas during heavy rainstorms, and be sure to keep them clean year-round.

Basement Waterproofing Tips

Discover our top 7 tips on waterproofing your basement. Follow these to prevent basement floods and leaks and to prevent the dreaded “wet basement”.

1. Check your gutters

A large majority of issues with water build up around the edge of the house happens because of improper drainage of water off the roof.

Make sure your gutters are clear of debris and all drainage pipes are properly directed away from your house at least 6-10ft and are sloped away from the house. Gutters should be installed on every roofline that is parallel to the ground, including over windows and doors.

Next time there is a thunderstorm, grab an umbrella, head outside, and take a look at your gutters. Gutters too small may not be able to properly move the water fast enough down the drainage pipes. If you see overflow from the edge, you either have a built up problem with debris, or your gutters aren’t large enough.

2. Install window well covers

During the winter snow may begin to build up inside an exposed window well, which could eventually leak into the basement through the basement window or cracked foundation. During the summer, intense rainstorms can pool water up to a few inches in a matter of minutes. A properly fitting window well cover can protect your well from rain, snow, and debris build up and prevent basement leaks.

3. Ensure your window wells drain properly

Most newer homes have proper drainage systems put in place for window wells, drawing water away from the home with a weeping tile system. Take a look to see if any water is pooling in your window well, and keep the bottom of the well free from debris, as this could indicate a problem with your drainage system.

4. Check the seams of your basement windows

Improperly installed basement windows could lead to basement leaks if your window well gets exposed to too much water, or you do not have a window well cover installed. Check for cracks around the edges and seal with caulk if necessary. Older windows may leak at the seams even if no visible cracks are there!

5. Apply a concrete sealer

If you have an unfinished basement, you can easily apply concrete sealers to your walls and foundation in order to seal up microscopic cracks and crevices that water may seep through. Many big box stores sell concrete sealers that can help you waterproof your basement and come with easy to follow instructions to do it yourself!

6. Install a drainage membrane

A permanent solution to basement flooding could be to install a drainage membrane along the foundation wall that will channel water along the outside of the basement wall toward the foundation drainage pipe. Installation is not generally a DIY solution, and would require extensive excavation on pre-existing homes. This may not be a cost effective solution for many.

7. Bring in the sump pump.

If all else fails, now it’s time to bring in the big boys… if you have a ton of water build up in your wells or around your foundation, you may be in need of a sump pump to move the water away from your foundation through a discharge pipe. Again, this is generally not a DIY project, and best left to the pros.

EXPERT TIP: Concrete sealers won’t be able to fill in large cracks in your walls and foundation. Before applying the first coat of your concrete sealer, use recommended polyurethane caulk to fill the big gaps first!
