Basement Floor Cracks – They’re More Than Just Unsightly

Basement Floor CracksBy now, if you’ve been reading some of the articles on our blog, you probably know that water in your basement can cause a lot of problems.  You also probably know that water can enter your basement in several ways – through cracks, gaps or porous areas in the foundation, through gaps in or near a window frame, through the cove joint (the area where the basement floor meets the walls), or over the top of the foundation.  What you might not realize is that water can also come into your basement from the bottom up.

Yes, those cracks in your basement floor are more than just unsightly.  They’re a pathway for water to come in, and when they exist they require basement waterproofing just as much as cracks in a foundation wall.  As a general rule, floor cracks won’t let large amounts of water flood in, but any amount of dampness can lead to problems.  For one thing, a damp basement provides the perfect environment for the growth of toxic mold.  And, if your basement is finished, your expensive carpeting, furniture, decorations, and even the drywall can be ruined.

Basement floor cracks can let water seep in for a few different reasons, but the most common reason is naturally occurring hydrostatic pressure.  The water table of the soil beneath your basement rises when the ground becomes saturated by frequent heavy rains.  The pressure caused by an excessively high water table can force water up and through cracks in the basement floor.  You may have seen the signs of this type of water seepage – a chalky, grayish-white area on both sides of a crack in the floor.  What you’re seeing is the minerals that are left behind after the water has evaporated.

Other, less common causes of seepage include a failed sump pump or a failed exterior drain tile system.  In both cases, the failure leads to a buildup of hydrostatic pressure beneath the basement floor because the excess water has nowhere else to go.  As with naturally occurring hydrostatic pressure, the excess water is then forced up through cracks in the floor.

When water is seeping up through cracks in your basement floor, it’s important to have it evaluated by an expert seepage Chicago contractor.  They’ll be able to identify the best basement waterproofing solution and install it promptly and professionally.  Correct the problem quickly, so you can prevent the need to make more extensive repairs in the future.  Basement floor cracks aren’t just unsightly – they can make your living environment unhealthy and undermine your home’s value.  Contact a professional seepage Chicago contractor as soon as you see any signs of water seeping into your basement.
