Serving Windsor, Ontario • 4 min read
Many homeowners attempt to raise their ground level for landscaping and use their existing fence to contain the new dirt. However, placing wet dirt and heavy soil directly against fence boards creates extreme lateral pressure that the structure was never designed to handle. This practice not only pushes posts to lean over time but also creates a "moisture trap" that accelerates wood rot at the most vulnerable point of the post.
Why is putting dirt directly against a fence a recipe for failure?
When soil is piled against a fence, the weight of the heavy earth exerts constant lateral pressure on the boards and posts. In Windsor, where the clay-heavy soil can become particularly heavy when saturated, this pressure is significantly magnified. Because a fence acts like a sailboat catching the wind, adding the "dead weight" of soil at the base makes it nearly impossible for the post to remain upright. Furthermore, the moisture in the soil leads to rapid fungal growth; even a fence that is only 30 years old can exhibit severe rot when buried in landscaping.
Can I use my existing fence to hold back landscaping soil?
No, a fence should never be used as a structural container for dirt. A proper, separate retaining wall is required to hold back soil, and it should never come into direct contact with the fence itself. In Windsor, the high average moisture level ensures that any soil touching wood will keep the timber perpetually damp, leading to the localized rot seen at the ground line. By keeping a clear gap between a retaining wall and the fence, you allow for proper drainage and airflow, which are essential for preventing premature structural failure.
How do raised flower beds accelerate wood rot and structural leaning?
Building flower beds directly against a fence creates a localized environment of high humidity and constant moisture. This environment is the primary cause of rot at the ground level, which is often surprising to homeowners who see that the upper portion of their fence remains "beautiful" and healthy. This rot does not travel up the post; instead, it eats away at the base until the post can no longer support the weight of the fence or the moderate wind loads found in Windsor.

Frequently Asked Questions
Can I just put a piece of wood against the fence to hold the dirt?
No, adding more wood will only trap more moisture. You need a structural solution, like a separate retaining wall, that does not touch the fence.
Does the rot caused by the dirt spread to the rest of the fence?
Evidence shows that rot is typically concentrated at the ground line where the moisture is highest and does not travel vertically into the dry sections of the post.
Is it too late to save my fence if it's already leaning from landscaping?
If the upper sections of the posts are still healthy, our specialized steel fixtures can be installed to restore structural integrity without needing to replace the entire fence.
