Salt can have a detrimental effect on a home foundation especially where your driveway meets the home foundation. Particularly if it is used for de-icing purposes in colder climates. Here are some ways in which salt can impact a home foundation leading to the apron sinking:

  • Accelerated Concrete Deterioration: Salt can accelerate the deterioration of concrete, which is commonly used in foundations. The salt can penetrate the porous surface of the concrete and promote the corrosion of reinforcing steel inside, leading to cracks and structural damage over time.

  • Expansion and Contraction: When salt is used to melt ice on driveways, sidewalks, or around a home, the process of freezing and thawing can cause the water absorbed by the concrete to expand and contract. This expansion and contraction can lead to cracking and weakening of the foundation.

  • Soil Composition Changes: Salt can alter the composition of the soil around the foundation. It may lead to an increase in soil salinity, affecting its ability to provide proper support to the foundation. Changes in soil composition can result in uneven settling or heaving of the foundation, leading to structural issues.

  • Water Drainage Problems: Salt can also impact the drainage around a home. If not properly managed, salt-laden water runoff can accumulate near the foundation. Excess moisture can contribute to soil erosion and create hydrostatic pressure against the foundation walls, potentially causing basement leaks and foundation damage.

To minimize the negative effects of salt on a home foundation, consider the following:

  • Use Alternatives: Use alternative de-icing materials that are less harmful to concrete, such as sand or calcium magnesium acetate.

  • Proper Drainage: Ensure that the grading around your home promotes proper drainage away from the foundation. This helps to prevent water accumulation and reduces the risk of soil erosion.

  • Seal Concrete: Apply sealants to concrete surfaces to create a barrier against water and salt penetration.

  • Regular Inspections: Regularly inspect your foundation for any signs of damage, such as cracks or settling. Prompt repairs can prevent issues from worsening.

Taking proactive measures and using alternatives to salt can help mitigate the potential negative impact on your home foundation.
