Do I Need Basement Waterproofing?

There are some telltale signs to look for to help you determine if your basement should be waterproofed.

Water puddle on a basement floor

Water stains, mold, and rust are typical symptoms of leaky basements in PA, WV, & OH.

Symptoms of a wet or leaky basement include:

  • Water stains on the walls or floor (carpets, drywall, and wood surfaces)
  • Musty, damp odor
  • Efflorescence (white, powdery stains)
  • Visible mold and mildew growth
  • Unexplained "flu-like" illnesses or chronic symptoms
  • Puddles of water around the foundation
  • Rust or corrosion of metal materials
  • Rotted wood

Any of these signs would tell you that you need to consider some waterproofing. If you ignore your basement water problem, you won't be able to safely use the basement for storage or a finished space.

Causes of Flooded or Wet Basements in PA, WV, & OH

Flooding is the most common natural disaster across Pennsylvania. Wet basements in Western PA, Northern West Virginia, and Eastern Ohio are often caused by heavy spring rains, summer thunderstorms, snow melt, and flash floods. When your basement floods, it's important to know why, in addition to understanding your options for repair. There are two primary factors that contribute to flooded or damp basements:

  • Clay Bowl Effect

    Illustration showing the clay bowl effect

    Excavated soil that's replaced around a completed foundation isn't as dense and tightly packed as undisturbed soil farther away. As a result, water collects in the soil immediately surrounding the house, putting pressure on foundation walls and causing cracks.

  • Hydrostatic Pressure

    Illustration showing hydrostatic pressure

    The weight of the water in the soil around the foundation exerts pressure, forcing the water through cracks, gaps, holes, and around windows leading into the basement.

  • How We Fix Wet Basements in Greater Pittsburgh

    Our waterproofing specialists will be able to identify where the water in the basement is coming from and determine which waterproofing method and products are the most appropriate. They'll also be able to handle repairs on the exterior of the home, including extending downspouts to improve drainage around the foundation.
