Why Do So Many Basements Leak?
We feel like our homes are a safe haven and when something like a water leak disrupts that safety, it can be very unsettling and stressful. So why do so many basements leak? Let’s take a look at the 5 main causes of basement leaks.
- As the ground becomes saturated, water pressure builds against the structure (62.4 lbs. per cubic foot). The rising water then seeks cracks and weak points in the foundation caused by the natural expansion and contraction of concrete.
- Your home’s builder installed exterior footer drains and also applied a tar/asphalt type substance to meet local building codes and minimize water leakage, but the exterior footer drains malfunction forcing water under the footer. This action produces hydrostatic pressure under the floor, forcing water up through floor cracks.
- Because the footer and basement walls were poured separately, this produces a natural seam (cove) which water seeks. This is the most common source of water problems.
- The original waterproofing coating over the basement walls becomes dry and brittle leaving cracks in the coating. Water will penetrate these cracks filling the cavities inside the blocks. Often this water will sit and stagnate producing excessive mold and mildew.
- Due to the porous nature of concrete, bleeding and sweating will occur once water comes in contact with the concrete. This can also be a result of the deteriorating waterproofing membrane.
The bad news is that there are 5 main causes of basement leaks. The good news is we are here to help!
