How is it possible for water to penetrate my basement wall and get into my basement, which appears so watertight? Don’t panic.

Continue reading to find out about basement wall solutions that are wet for your home.

What causes a wet basement wall?

Wet basement walls, also known as “weeping”, are caused by moisture in the ground getting into the wall through cracks, seams, and around pipes. Wet basement walls are more common where water touches porous areas of a wall.

Wet basement walls could be caused by:

  • Small leaks can be caused by soil erosion or pressure from the outside.
  • Failure of building materials
  • Multiple freeze-and-thaw cycles.
  • Saturated ground – If the ground around your basement is constantly wet or saturated, you have a higher chance of basement walls.

How to stop water from seeping through basement walls

Your basement and contents are vulnerable to mold growth and damage if it has a wet basement wall. Even a tiny amount of moisture can lead to major problems. You should take immediate action if your basement walls are weeping.

These are our top recommendations for dry basements

  1. Sealing wall cracks
    To fill wall cracks that allow water to seep through, apply a coat hydraulic cement. For a high-quality finish, follow the manufacturer’s instructions. The temporary fix is not permanent as foundation shifts can cause cracking. For more permanent solutions, consult a local contractor.
  2. Reroute water sources from the exterior
    Water can seep from your home due to large amounts of precipitation, faulty gutters or leaking hoses. Water can be prevented from entering your basement by the following:
  • Gutter cleaning and inspection should be done regularly.
  • To direct water further away from your foundation, you can install gutter extensions.
  • Checking for leaks in hoses or spigots.
  • Grading soil away form the foundation (so that heavy rain does not roll away from your home).
  • To prevent foundation cracks, plant trees, shrubs, and bushes far from the foundation of your home.

Windows that are waterproofed
Basement windows (regular or egress) can allow moisture to enter your basement. Old windows can be replaced or repaired to prevent water from entering your basement walls.

Waterproof basement and walls
There are many waterproofing options available. A local contractor might be able to offer additional relief by installing French drains around your home.
