What Causes a Retaining Wall to Lean?
Poor Drainage Behind the Wall
Poor drainage behind the wall is one of the common causes of a leaning retaining wall. When water accumulates behind the wall, it increases the pressure on the structure, causing it to lean.
Inadequate Base or Foundation
An inadequate base or foundation can also lead to a leaning retaining wall. If the base is not properly compacted or the foundation is not strong enough, the wall may not be able to withstand the pressure from the soil or gravel it is holding back.
Pressure from Soil or Gravel
The pressure from the soil or gravel behind the wall can cause it to lean. If the soil is not well-compacted or there is too much pressure from the backfill material, the wall may start to tilt.
How to Fix a Retaining Wall that is Leaning?
Assess the Condition of the Wall
The first step in fixing a leaning retaining wall is to assess its condition. Determine the extent of the damage, the cause of the lean, and whether it can be repaired or needs to be completely rebuilt.
Properly Prepare the Ground
One of the key steps in preventing a retaining wall from leaning is to properly prepare the ground before construction. This includes ensuring that the soil is well-compacted and the area is properly leveled.
Digging Behind the Wall
In order to repair a leaning retaining wall, you will need to dig behind the wall to access the base and foundation. This will allow you to remove any damaged sections and make necessary repairs.
Rebuilding the Wall with Proper Materials
If the damage to the retaining wall is extensive, it may be necessary to rebuild it using proper materials. This ensures that the new wall is strong and able to withstand the pressure from the soil or gravel.
Ensure Proper Drainage
To prevent water accumulation and pressure behind the wall, it is important to ensure proper drainage. This can be achieved by installing drain pipes or creating a drainage system that directs water away from the wall.
When to Call a Professional to Fix a Leaning Retaining Wall
Extensive Damage or Lean
If the retaining wall has extensive damage or is leaning significantly, it is advisable to call a professional for assistance. They have the expertise and equipment to handle complex repairs and ensure the stability of the wall.
Presence of Trees or Roots
If there are trees or roots near the retaining wall, they can exert pressure that causes the wall to lean. In such cases, it is best to seek professional help to assess the situation and determine the appropriate course of action.
Multiple Walls in Poor Condition
If you have multiple retaining walls on your property and they are all in poor condition or showing signs of leaning, it is recommended to consult a professional. They will be able to evaluate the overall stability of the walls and suggest the necessary repairs or replacements.
