Boundary Retaining Wall Collapse: Responsibilities and Cost-effective Solutions

In the unfortunate event of a boundary retaining wall collapse, determining responsibility and finding economical solutions are crucial. When faced with maintenance or rebuilding needs, both parties involved may hesitate to cover the expenses, leading to disputes.

To resolve such conflicts, the first step is to review the property deeds. In cases where no explicit information is available, the legal stance considers both parties equally accountable for retaining wall upkeep. However, consultation with legal professionals is advised to fully comprehend the specifics outlined in the Party Wall Act.

What are the most cost-effective methods of rebuilding a failed retaining wall?

The answer depends on the type of retaining wall and the nature of the failure. The two most common scenarios are as follows:

1. Timber criblock retaining walls:

These walls often suffer from rotting criblock frames and falling stones, resulting in instability. Rebuilding such walls requires demolition, followed by the construction of a new retaining wall. Alternatively, another retaining wall can be built in front of the existing one. In this case, a recommended approach is to opt for a slim and sturdy king post retaining wall, provided that the ground conditions allow it.

2. Retaining walls lacking proper design:

When a retaining wall lacks adequate design, it may not possess sufficient mass to resist external loads. In such instances, demolishing the current wall and reconstructing it based on proper design principles is necessary.
