Understanding Garage Floor Cracks

What Causes Garage Floor Cracks?

1. Temperature Changes

   • When it’s cold, water in the concrete can freeze and expand, making cracks.

2. Bad Construction

   • If the concrete wasn’t mixed well or dried properly, it can crack.

3. Foundation Settling

   • The ground under the garage can sink, causing cracks in the concrete.

4. Heavy Loads

   • Too much weight from cars or storage can cause the concrete to crack.

Types of Garage Floor Cracks

1. Hairline Cracks

   • These are very thin and might not be serious but can get bigger.

2. Shrinkage Cracks

   • Happen when the concrete dries and shrinks, usually not a big problem.

3. Settlement Cracks

   • Caused by the ground underneath settling.

4. Structural Cracks

   • These are serious and may need a professional to look at them.
