Signs Your Retaining Wall Needs Fixing

Retaining walls are essential in landscaping, preventing soil erosion and maintaining stability. It's important to recognize the signs of failure, which can result from poor drainage, improper construction, settlement, or freeze-thaw cycles. Heavy rain can strain your wall, but with regular inspections, you can catch issues early before significant damage occurs. We encourage you to step out and take a look. During your inspection, here’s what to look for:

#1: Cracks

Visible cracks can indicate structural weakness. Small cracks may seem insignificant, but they can quickly widen and compromise the wall's integrity.

#2: Leaning or Bulging

This suggests severe stress and potential failure. Early intervention can involve reinforcing the wall, improving drainage, or rebuilding sections.

#3: Water Pooling

Excess water can build up pressure, pushing the wall outward. Proper drainage is crucial for maintaining the stability of a retaining wall.

#4: Soil Erosion

Proper drainage systems is key in preventing soil erosion. When soil is washed away, the support that the wall relies on is compromised, leading to instability.

#5: Efflorescence

White, chalky deposits indicate water penetration. While efflorescence itself is not structurally damaging, it is a sign of excessive moisture, which can lead to more severe issues like weakening of the wall material, increased cracking, or even mold growth.

#6: Gaps

Increasing gaps between the wall and adjacent structures suggest movement and settling. This movement can weaken the wall’s structural integrity and lead to further displacement, cracks, or failure.

Puddles are fun for kids, but not for your landscape! Pooling water can weaken your structures and lead to serious damage.

Repair or Rebuild?

After inspecting your wall, you might notice some key indicators. For instance, if the wall appears uneven across the top, it could signal freeze/thaw issues. In such cases, the wall base may need to be redone, as it indicates deeper structural problems. On the other hand, for newer or minor issues, your landscape professional will be able to assess the type of damage and propose a solution.

In either situation, be sure to consult with a professional before moving forward. You'll want to avoid spending money on "band-aid" solutions for major problems, as they won't address the underlying issues and can lead to more significant expenses in the long run.
