What Causes Basement Leak Between Wall and Floor?

There are many things that can cause a leak between the wall and floor of your basement.

1. Foundation Cracks

One of the most common causes of basement leaks is cracked foundations. This happens when the foundation walls shift or settle due to age, excessive weight, improper construction and other factors. Even a very small crack can let in enough water to cause a leak.

2. Poor Drainage System

Another possible cause of basement leaks between the wall and floor is poor drainage. The foundation of your home is designed to keep water out, but if the soil around your home is uneven or an adequate drainage system is not installed, water can easily seep into your basement.

3. Grading

The grading around your home should be done so that it slopes away from the house. If the ground around your house is not graded correctly, water can easily get into the basement. So this can be another reason of basement leak between wall and floor.

4. High Water Table

The water table is the level at which underground water is present. If your home is built on a high water table, that can cause problems such as flooding or leaking in your basement. Also, if the water table rises due to heavy rains or floods, it can lead to leaking in your basement.
