What is Negative Grading?

Negative grading occurs when the soil around the foundation of your home slopes towards the house, instead of away from it. This can happen for a variety of reasons, such as settling soil, poor initial landscaping, or erosion over time.


What are the Risks of Negative Grading?


Negative grading can lead to several issues that can damage your home and impact your quality of life. The most common risks include:

  1. Water Damage - Negative grading can cause water to accumulate around the foundation of your home, leading to water damage in your basement or crawlspace.

  2. Foundation Issues - The accumulation of water around your foundation can lead to structural damage, including cracks in your foundation and shifting walls.

  3. Pest Infestation - Pests, such as termites, love damp environments. Negative grading can create a perfect habitat for pests, which can lead to infestations in your home.

How to Fix Negative Grading


The good news is that negative grading can be fixed. Here are some solutions to consider:

  1. Fill in Low Spots - One solution to negative grading is to fill in the low spots around your home with soil. This will help create a slope away from your foundation.

  2. Install Drainage Systems - Installing a drainage system can help divert water away from your home, preventing water damage and foundation issues.

  3. Install Landscaping Features - Another solution is to install landscaping features, such as a rain garden or swale, which can help absorb water and prevent negative grading.

Negative grading around your home can lead to a range of problems, from water damage to foundation issues. If you suspect negative grading, it's important to address it promptly to prevent further damage.
