If your basement has ever flooded before, chances are it will do so again. Even if it hasn’t, there’s still a chance it could flood in the future, so you need to be sure your basement is fully waterproofed. There are numerous reasons why basements flood, many of which are preventable.

The most common reasons for basement flooding include gravity, problems with the walls and foundations, gutter problems, backed up sewers, and broken water lines. Basement waterproofing Des Moines can reduce the effects of these common issues.




Water flows downhill. Normally, your home should be placed on the highest point of your property. This directs water away from your house when it rains.

If the property isn’t graded correctly—or, in other words, if the ground is sloped down toward your home instead of away from it—water will flow down to your house, possibly accumulating around the point where it meets the ground. This could lead to water seeping into your basement and flooding it.

Fortunately, the effects of wind and rain can wear away at the higher points on your property. This brings their elevation down so that you don’t have as much of a slope toward your house. This takes years to happen, though, so it’s best to make sure your basement is waterproofed in the meantime.


Walls and Foundation Problems

Cracks in the walls or foundation of your basement allow rainwater to come in. These will develop over time, so you’ll want to check for them constantly. If you find a crack, get it fixed immediately.


Gutter and Downspout Issues

The gutters on your house are designed to safely direct water from your roof to the ground. If they’re badly designed, they could end up carrying water too close to your house’s foundation, leading to flooding. A good design should carry water at least four feet away from the building.

Gutters and downspouts also frequently get clogged with leaves, twigs, and other junk, so keeping them clean is key. If you don’t clean them out regularly, they won’t do their job.


Sewer Backups

Heavy rains could overwhelm sewer lines, causing them to back up into your home. Backups could also result from a clog somewhere in the line. If this happens, you’ll not only get rainwater in your basement but also unsanitary waste.

The extra water from the sewer lines will come back into your home through the lowest drainage points available, often a floor drain in the basement. Naturally, this causes a health hazard as well as property damage.


Broken Water Lines

Worn or broken plumbing leaks water into the walls and floors of your home. Since water follows gravity, this means it will eventually end up in your basement. Because of this, a flooded basement could be a sign of a plumbing problem and water damage in other places in your home.
