Leaks and seepage in basements are very common occurrences albeit rather hassling ones. They can pave way for a variety of problems including safety concerns, health impediments, high expenses, and structural damage. Knowing the causes behind basement seepage and leaks can help you identify the problems beforehand and even allow you to take preventive measures. Listed below are most of the major causes of having unwanted moisture and water permeation in your basement.

Hydrostatic Pressure

Hydrostatic pressure is one of the common causes for seepage and leaks. Since every ground surface has water underneath it, despite how dry it may be, every ground surface has a water table. A water table is the water present underground and it can be either high or low depending on the region. However, when this water table rises more than normal due to heavy rainfalls, storms, snowmelts, etc., the water table pushes against your home’s foundation. This is called hydrostatic pressure and it can easily allow water to penetrate your basement and cause leaks.

Sideways Pressure

This is pressure to the foundation that comes from the side and is mainly caused by the expansion of soil. Different types of soil have various drainage abilities but any kind of soil that absorbs water and is unable to drain it expands and presses against your home’s foundation from the side, causing cracks and leaks.

Window Wells

Window wells are another common causative factor for leaks and seepage, even though they have nothing to do with soil expansion. As is known, windows in basements let in light and air but in the case of rain or snowmelt, the windows can gather water. This occurs primarily due to a clogged drain or no drainage system. The accumulated water then seeps into the basement through the window, often even creating enough pressure to push the window in.

Vapor Diffusion

Vapor diffusion is the process of moisture seeping in in vapor form. Vapor can enter through different materials and the permeability of every material determines the level of moisture permeation. In basements, moisture in vapor form can easily penetrate through the moist concrete walls or floors into the dryer surfaces of your basement. The solution to vapor diffusion is normally foundation waterproofing.

Any leaks or seepage left ignored can make your basement a popular breeding region for mold or mildew, which causes health problems. Furthermore, cracks and leaks can deteriorate the quality of your foundation and the more the problem worsens, the higher the cost of repairs will be, which is why it is always best to get basement repair professionals to inspect your basement for any leaks or seepage.
