Basement Moisture Causes and Dangers

Homeowners are often pretty concerned with preventing their basement from getting flooded and with good reason. It can be extremely tedious and time-consuming to recover from basement flooding causes such as pipe leaks, sewer overflows or foundation leaks and flooding from natural conditions like excessive rainfall, snow melt, etc.

Preventing basement leaks involves locating and fixing the cause of your basement leak, drying your basement out completely to prevent the buildup of mildew and mold; and then repairing or replacing anything that may have been altered, such as drywall. However, it’s more common for basement spaces to get impacted by moisture problems which are also far less obvious and therefore often not noticed.

Basement Mold Dangers

A damp basement area is more than just an annoyance. Whether your basement is unfinished and used largely for storage, a finished living space, or simply a crawl space; excessive moisture here can lead to:

  • The growth of mildew, mold or other biological growth that has the potential to cause a range of health problems
  • In more severe cases, these conditions can result in rot and structural damage Unlike flooded basements, damage from moisture occurs over a much longer period of time.

Signs of Basement Moisture

Because your basement is under the ground level, it will naturally have more moisture than the upper stories of your home. So how do you identify if you really have a moisture problem? Here are some of the obvious signs to look out for:

  • A musty, unpleasant odor and a feeling of very humid and damp air
  • Rings of dampness around the lower levels of concrete block walls
  • Seepage during heavy rainfall
  • Water trickling out of the floors and walls
  • Condensation on the basement surfaces

Basement Flooding Causes

The three main causes of basement flooding include:

Surface runoff

Flowing water on the ground’s surface poses great threat to your basement. The lateral hydrostatic pressure against walls eventually seeps through wall’s cracks and gaps. The porous soil standing next to walls can also cause basement water.

Subsurface Water

If you find that your basement is almost always wet even when there is no storm, your foundation might be positioned on a high water table. A rise in the water level causes pressure against your concrete flooring and forces water through the ground.

Condensation

This is commonest overlooked causes of moisture in basements. Condensation tends to show up in the form of droplets on the floors and walls. It occurs when the warm air through the vent windows comes into contact with any cold surfaces or un-insulated pipes in the room.
