Having a crack in your basement floor can be an eyesore and make any homeowner stressed out. But when it comes to fixing a crack in the basement floor, you don’t need to worry!
With some basic preparation, knowledge and access to the right materials – repairing a cracked basement floor is something that anyone can do relatively quickly and easily.
In this article, we will cover why cracks develop on your basement floors, what causes them and provide the best solutions for resolving all kinds of cracks in your basement floors.
What Causes Basement Floor Cracks?
The most common cause of basement floor cracks is moisture. If water seeps into the foundation and saturates the soil underneath, it can cause pressure to build up against the walls and floors. This pressure can be enough to eventually create a crack in your basement floor.
Wear and Tear
Basement floors may also crack due to wear and tear. Years of activity, heavy furniture, foot traffic, mould growth, settling soil and other factors can all contribute to cracks in your basement floor.
Air Pressure Differences
Another reason that basement floors might crack is because of a difference in air pressure. This happens when the air pressure outside the basement is different from the air pressure inside.
This could be because there is a lot of air flowing into the basement, or it could be because the ventilation system is not working well.
Poor Drainage Around the Foundation
If there is poor drainage around the foundation, this can also cause cracks in your basement floor. Poor drainage means that water will be held against the foundation for prolonged periods of time, creating pressure and eventually leading to a crack.
Heaving
Heaving is when the soil around the foundation expands and contracts due to changes in temperature. This can cause pressure on the basement floor, which can lead to cracks.
Shrinkage
Finally, shrinkage of concrete is another reason that your basement floor might crack. As concrete dries, it shrinks and this can cause cracking in the basement floor.
Settlement
Settlement can also cause cracks in the basement floor. When soil shifts and moves, it can cause the foundation to settle, which will create pressure and eventually lead to a crack.
Frozen Soil
Another reason why your basement floor might have cracks is because of frozen soil. When the ground around your house freezes and then melts, it can push down on the basement floor, which causes cracking.
What Do Cracks In Basement Floor Mean?
Hairline Cracks
Hairline cracks are not a big problem and can be fixed with a simple patching material.
Cracks Between 1/16” and 1/8”
These cracks are a bit bigger than hairline cracks. They might be in your basement floor, but they might also be in the walls or near doors and windows.
These types of cracks should be inspected by a professional to determine whether they need to be repaired.
Larger Than 1/8-Inch
If you find a crack in your basement floor that is larger than 1/8-inch, it’s important to take action right away. These types of cracks can indicate serious structural problems and should be inspected by an experienced contractor or foundation specialist.
Between Basement Wall and Floor
If you find a crack between the basement wall and floor, it could be a sign of serious structural problems. You should have this inspected by an experienced foundation specialist to determine the best course of action for repairing the crack.
Is Crack in Basement Floor a Problem?
Yes, cracks in your basement floor can be a serious problem if not repaired properly. They can cause structural damage and even lead to water leaks or flooding. It’s important to have any cracks inspected by a professional so that the correct repair method can be used.
Water Leaks
If you have a crack in the basement floor, it can lead to water leaks. This is because the crack will allow moisture to seep in, which can cause damage to the foundation and walls of your home.
Pests
Cracks in the basement floor can also attract pests. They can use these cracks as entry points and make their way into your home.
Structural Damage
Cracks in the basement floor can cause damage to the structure of the house. The pressure from the crack can make the foundation weaker and cause bigger problems later on.
