Knowing When to Replace Your Retaining Walls

Knowing When to Replace Your Retaining Walls

Retaining walls are subject to damage and may eventually require repairs or replacement.

Retaining walls can be a good addition to your yard, providing structure, aesthetic appeal, and functionality. They can also help negate soil erosion and protect your property from damage as caused by shifting soil. However, like any outdoor structure, retaining walls are subject to damage and may eventually require repairs or replacement.

Material Concerns

Most retaining walls are constructed from concrete, wood, or stone. While these materials are strong and durable, they can deteriorate over time, especially in wet or humid climates. Wood retaining walls, in particular, are prone to material failure. To prevent this, consider using concrete or stone for your retaining wall construction. If you prefer wood, use a more durable type such as fir, pine, or cedar, and ensure it is pressure-treated before installation.

Deep-Rooted Trouble

Tree roots can bring damage to retaining walls by pushing against the structure, leading to cracks and other damage. The best way to prevent this is to avoid placing your retaining wall near large trees, shrubs, or other plants. If your wall is already in place, you may need to relocate nearby plants or replace damaged materials.

Drainage Issues

Excess moisture can cause a retaining wall to bow or lean, making it unable to withstand pressure. Poor drainage is often the culprit behind this issue. Installing a drainage system can help reroute water away from the wall, but if that’s not practical, you can also backfill with materials like pea gravel to improve drainage.

Structural Integrity

A retaining wall must have a firm foundation, stable footing, and necessary structural reinforcements to remain strong and functional. If it is poorly constructed, it can crack, crumble, or even collapse. It is crucial to hire a landscape designer who can ensure your retaining wall is built to last.
