How do you stop a retaining wall from failing?
Following are the methods to prevent failure and distress in retaining walls:
- Redeem surface drainage problems.
- Reduce retaining wall height.
- Use tie backs.
- Extend the footing.
- Remove and replace backfill materials.
- Reinforce the front of the wall.
- Add a key.
- Use cantilevered soldier beams.
What causes a retaining wall to fail?
The main cause of retaining wall failure is poor drainage. Without proper drainage, hydrostatic pressure builds up behind the retaining wall. Saturated soil is substantially heavier than dry soil, and the retaining wall may not be designed to handle such a load.5 Jan 2012
How do you tell if a retaining wall is failing?
Here are a few signs of a failing retaining wall:
- The wall is collapsing or tilting. When a retaining wall begins to tilt, it is usually the result of soil issues or poor construction.
- The wall is starting to crumble.
- Separation from adjacent walls.

Do you need drainage behind a retaining wall?
Second, a retaining wall must have properly compacted backfill. In order to provide proper drainage, at least 12 inches of granular backfill (gravel or a similar aggregate) should be installed directly behind the wall. Compacted native soil can be used to backfill the rest of the space behind the wall.
How long do retaining walls last?
A concrete retaining wall can be expected to last anywhere from 50 to 100 years. Meanwhile, a brick masonry wall can be expected to last at least 100 years, though the quality of the work will play a role here.

WHY DO Retaining walls lean?
Pressure from the soil behind retaining walls may cause them to tilt or lean. Older retaining walls tend to be more prone to leaning than newer ones because “Mother Nature” and age works their magic over time. Walls that are not constructed or engineered properly also tend to tilt over time.
What is best material for retaining wall?
