Maintaining Your Retaining Wall 

Once you have built your retaining wall, it’s important to maintain it properly. This will ensure that the wall remains structurally sound and aesthetically pleasing. Here are some steps you can take to properly maintain your retaining wall in Central New York: 


Inspect regularly 

Check your wall on a regular basis for any signs of damage or instability. With the proper construction of an engineered, professionally built retaining wall, there will be very little to be concerned with. Ground conditions change and unknown situations can occur that could/may affect the wall. Regular check-ups of the wall are an invaluable proactive approach to managing any potential problems.


Signs of Failure

Retaining wall units or Segmented Retaining Walls(SRW), have joints created by each unit being side by side. Indicators that the current retaining wall is failing:


  1. The retaining wall has a "lean" to it. The wall is leaning in the wrong direction, toward the area it should be retaining
  2. The wall face is saturated, perpetually wet, and has a white crusty paste throughout the face
  3. The wall face is bulging (protruding) or an area has drooped or settled
  4. SRW units are not touching at joints. There appear to be larger gaps between joints


If you see any of these signs, it is time to intervene. 


Repair any damages immediately 

If you notice any damage to the wall, repair it as soon as possible, before the issue becomes worse. Contact the contractor who built the wall or if your wall a DIY, then consult with a local professional for repairs/replacement. 



Remove debris from behind the wall 

Make sure to clear away leaves, twigs, and other debris periodically from the area behind your retaining wall. This will help prevent water accumulation and soil erosion. 



The Disastrous Effects of Unsound Retaining Walls

A poorly designed retaining wall can lead to disastrous consequences. Inadequate drainage, an improper foundation, and incorrect materials can cause the wall to collapse or lean over time due to soil erosion and the weight of water-saturated soil behind it. This could potentially damage neighboring properties and put lives at risk. 



In addition, a structurally unsound wall can also lead to high repair costs. Improperly installed walls may require the services of a professional engineer in order to make sure that any repairs are done safely and correctly. 

Building a retaining wall is an important undertaking and one that should not be taken lightly. 


By taking the necessary steps, you can ensure your retaining wall will not only enhance the look of your property but also provide a safe and secure barrier for years to come. With proper planning and maintenance, your retaining wall will not only be aesthetically pleasing but also structurally sound.
