How Seasonal Shifts Can Affect Your Retaining Walls (And What to Do About It)

Retaining walls do more than hold back soil. They protect foundations, manage drainage, and add structure and style to landscaping. But like any outdoor feature, retaining walls are subject to the elements and seasonal changes can have a significant impact on their stability and longevity.

If you have a retaining wall on your property, here’s what you should know about how seasonal shifts can affect it and what steps you can take to protect your investment.

Temperature Fluctuations and Expansion

As temperatures shift from warm to cold, materials expand and contract. This is especially true in fall and winter when daytime temperatures can drop rapidly overnight. For retaining walls made of concrete, stone, or brick, repeated freeze-thaw cycles can cause cracking or mortar deterioration. Over time, this can lead to structural failure if not addressed early.

Soil Movement and Pressure

When the seasons change, so does the moisture content in the soil. In the spring and fall, increased rainfall can cause soil to expand. During drier months, the soil contracts. This constant movement adds stress to retaining walls, particularly those that weren’t built with proper drainage or reinforcement. The result can be bulging, leaning, or cracked walls.

Drainage Problems in Wet Seasons

Poor drainage is one of the leading causes of retaining wall failure. In wetter seasons like fall and spring, water needs somewhere to go. If your wall doesn’t have proper drainage behind it, hydrostatic pressure can build up. This added pressure can push the wall forward or cause it to collapse.

What You Can Do About It

To protect your retaining walls from seasonal damage, start with a professional inspection, especially if your wall is older or showing signs of wear. Here are some preventive steps to consider:

• Check for cracks, leaning, or water pooling near the base

• Clear debris and leaves that block drainage paths

• Improve backfill and drainage behind the wall if needed

• Reinforce or rebuild sections that are failing

• Schedule seasonal maintenance before freeze-thaw cycles begin
