How Sewer and Septic Overflows Can Damage a Home's Foundation

Last updated 6 years ago

Has your home recently flooded due to a sewer or septic system overflow? If so, you may be dealing with a host of problems, including hazardous waste, sewer gasses, and other dangerous issues. However, sewer and septic system flooding can cause even bigger issues for your foundation. Here’s a look at how sewer problems can quickly lead to foundation problems.

  • Exterior Water Damage: Septic and sewer overflows originating outside the home cause many of the same issues as surface water and subsurface water. Waste water that infiltrates your home can endanger your foundation, much like water from sprinklers or downspouts. Common issues include hydrostatic pressure buildup, swelling soil, and the potential for leaks, bowing, and other types of foundation damage. Waterproofing and sealing foundation cracks on the outside can help to minimize the risk of damage.
  • Soil Contamination: Because of the toxic nature of septic and sewer waste, the soil around your foundation can also become contaminated. This soil may need to be removed, which can cause some foundational instability. In such an event, a foundation expert should be involved in the soil removal and backfilling of the soil around your home’s foundation.
  • Interior Water Damage: When overflowing happens indoors, through a sewer drain in your basement or crawlspace, a number of additional issues arise. Not only is your foundation at risk of damage, but will also be flooded with dirty sewer water, filled with pathogens and bacteria. If you have a proper drainage system established within your foundation, such as surface or French drains, and a sump pump, this issue may be mitigated much quickly.
