Reasons Why A Basement Can Leak throughout The Greater Philadelphia

If you know what causes the leak you will also know how to prevent it from the beginning. There are generally five reasons why a basement leaks.

Basement Leak in Greater Philadelphia
  • Hydrostatic Pressure: During heavy rain or melting snow ground absorbs water. When the soil is saturated it cannot absorb any more water, causing hydrostatic pressure (the pressure created by water within the soil beneath your foundation). It occurs when water gets trapped under the concrete flooring, having nowhere else to go. As a result, water leaks through the foundation walls and floor.
  • Lateral Pressure: As, while building your house the soil gets excavated and filled back in later on. The looser the soil is the greater amount of water it absorbs and the more water is absorbed the more the soil expands. After heavy rain this expansion of soil creates pressure against the foundation from sideways, causing cracks on your wall and resulting in water leaking into your basement.
  • Faulty Plumbing: Water can leak into your basement if any pipe is leaky inside your home. A leaky pipe may also lead to pipe bursts and ultimately flood your basement.
  • Window Well: A window well is a common cause of a basement leak. If the window is not installed properly or doesn’t have proper drainage, or the drain is blocked or clogged by debris; rainwater accumulates within the well and built pressure on the window and window seals. Eventually, the window seal fails and water seeps through. Cracks and gaps around the window can also cause water leaks into your basement.
  • Malfunction of Sump Pump: A sump pump is a piece of essential equipment to pump away water from the floor and foundation and never let water gather under the flooring. But, if it’s not cleaned regularly or properly maintained, it can fail to divert the water away. As a result water leaks into your basement.
