Why is my Basement Wet?

There are many reasons why basements are wet. Some simple causes that should be ruled out before installing a waterproofing system are:

  • Leaking window wells
  • Poor grading around the home
  • Sump pump failure
  • Ineffective sump pumps
  • Blocked gutters
  • Clogged downspouts

The most common, and most problematic, reasons for water intrusion are:

  • High Water Table. The water table in your area exists around and under your home. It fluctuates based on rainfall and melting snow. Many homeowners experience water entry when the water table gets high.
  • Hydrostatic Pressure. Water exists under and around your home before it seeps into the soil. This water becomes pressurized. Raised pressure levels cause the water to seek entry through cracks and crevices in walls and floors. It can be helpful to think of pushing a beach ball into a pool.
  • Settlement. The earth and soil around your home is continually settling. The resulting movement can shift your foundation. This can cause your foundation to shift and crack allowing water into and under your walls and floor.
