Common Problems with Retaining Walls and How to Fix Them

Retaining walls are essential for managing soil erosion, creating level areas in sloped landscapes, and enhancing the overall appearance of your outdoor space. However, like any structure, retaining walls can encounter various issues over time. In this blog, we'll explore some common problems with retaining walls and how to fix them.

1. Cracking

Problem: Cracking is a common issue in retaining walls, often caused by the pressure of the soil behind the wall, temperature fluctuations, or the natural settling of the ground. Small cracks can become larger over time, leading to structural weakness.


  • Inspection: Regularly inspect your retaining wall for any signs of cracking. Small cracks can be filled with masonry crack filler.

  • Reinforcement: For larger cracks, it may be necessary to reinforce the wall. This could involve adding additional support or rebuilding sections of the wall.

  • Professional Help: If you’re unsure about the severity of the cracks, it’s best to consult with a professional. Contact us to assess the damage and provide an effective solution.

2. Leaning or Bulging

Problem: Leaning or bulging walls indicate that the wall is not withstanding the pressure exerted by the soil. This can be due to poor construction, inadequate drainage, or soil movement.


  • Drainage Improvement: Ensure proper drainage to reduce the pressure on the wall. Installing weep holes or a French drain can help divert water away from the wall.

  • Reconstruction: In severe cases, part of the wall may need to be rebuilt with additional reinforcement such as tiebacks or anchors.

  • Regular Maintenance: Regularly check for signs of leaning and take action early to prevent further damage. For professional evaluation and repair, contact us to get a free estimate.

3. Water Accumulation and Drainage Issues

Problem: Poor drainage can lead to water accumulation behind the wall, increasing pressure and causing the wall to fail. Water buildup can also lead to soil erosion and the growth of mold and mildew.


  • Proper Drainage System: Install a proper drainage system behind the retaining wall, such as gravel backfill, perforated pipes, or weep holes to allow water to escape.

  • Regular Cleaning: Keep the drainage system clear of debris to ensure it functions effectively.

  • Sealing: Apply a waterproof sealant to the wall to prevent water from seeping in and causing damage.

  • Consult Experts: For optimal drainage solutions tailored to your wall, reach out to us. Our experts can provide a comprehensive assessment and recommend the best course of action.

4. Soil Erosion

Problem: Soil erosion behind the wall can undermine its stability, leading to cracks, bulging, or collapse. This is often caused by inadequate drainage or vegetation removal.


  • Vegetation: Planting vegetation can help stabilize the soil and reduce erosion. Choose plants with deep root systems that can hold the soil in place.

  • Erosion Control Measures: Use erosion control blankets or geotextiles to prevent soil movement.

  • Retaining Wall Design: Ensure the retaining wall is designed with proper slope and drainage to minimize erosion risks.

  • Professional Services: For advanced erosion control techniques and wall design improvements, contact us for expert assistance and a free estimate.

5. Pest Infestations

Problem: Pests like ants, termites, and rodents can burrow into retaining walls, causing damage and weakening the structure.


  • Pest Control: Regularly inspect the wall for signs of pest activity and take immediate action to control infestations.

  • Preventive Measures: Apply pest-resistant treatments and maintain the area around the wall to discourage pests from settling.

  • Professional Intervention: If pest damage is significant, professional repair and pest control services may be necessary. Contact us to schedule an inspection and receive a free estimate on repairs.

6. Foundation Issues

Problem: Foundation problems can cause the retaining wall to shift or settle unevenly. This is often due to poor soil conditions, inadequate compaction, or water infiltration.


  • Soil Testing: Conduct soil tests to determine the stability and composition of the soil before building a retaining wall.

  • Foundation Reinforcement: Use proper foundation materials and techniques to ensure the wall's stability. This might include deeper footings or using geogrid reinforcement.

  • Monitoring and Maintenance: Regularly monitor the wall for signs of foundation issues and address them promptly to prevent further damage.

  • Professional Advice: For foundation-related concerns and reinforcement solutions, reach out to us.

Retaining walls are valuable structures for both functionality and aesthetics in your landscape. However, they require regular maintenance and occasional repairs to remain effective and attractive. By addressing common problems like cracking, leaning, drainage issues, soil erosion, pest infestations, and foundation problems, you can ensure your retaining wall lasts for years to come.
