Building a retaining wall is no simple feat, and the repercussions of improper retaining wall construction can be costly for businesses. To avoid distress and failures, it’s important to follow expert tips designed to ensure structural stability and longevity.
Here are five expert building strategies to prevent distress and failures of retaining wall systems.
Extending the footing
Building retaining wall systems that are structurally sound requires extra steps to ensure they will be able to withstand the pressure of the soil they support. A great way to do this is to extend the footing beyond the face of the wall. Doing this allows for an even distribution of load across a greater surface area, ensuring more balanced support for a structure. This increased level of support helps reduce overall stress on the wall itself, keeping it strong and secure over the long term. As a bonus, this technique will also help decrease potential erosion around your structure.
Removing and replacing backfill materials
It’s important to use backfill materials appropriate for a retaining wall system. When selecting the right backfill material, engineers keep in mind critical factors such as the amount of compaction, moisture level, particle size distribution and plasticity index. Other factors like local building codes and cost also play a role in determining the most appropriate material for your project requirements. In addition, it is recommended to remove any unsuitable material from beside or behind your wall before backfilling with suitable materials such as sand or crushed stone. This will help prevent long-term instability caused by changes in moisture content over time.
Reinforcing the anterior wall portion
Reinforcement bars should always be used at the top and bottom of a retaining wall system to provide extra strength and stability against lateral forces that could cause failure or distress over time. Additionally, using special devices known as deadmen can increase stability by providing additional tension on lateral forces acting against the structure.
Installing deepened key provision
A key provision is an integral part of constructing a successful retaining wall system, as it helps transfer load into underlying layers of soil or rock more effectively than other methods alone. To further increase its effectiveness, consider deepening this key provision into stronger soils or rocks below your existing layers. Doing so will add significant strength and stability against lateral forces applied to your structure.
Utilising cantilever soldier beams
Cantilever soldier beams can be installed beneath your foundation layer to provide additional support against vertical loads applied onto your structure from above-ground level areas such as driveways or walkways leading up to it. Doing so will help reduce sinkage due to these loads over time, thus preventing distress or failure caused by inadequate support along the vertical edges of your structure’s base layer.
Conclusion
When designing a retaining wall system, it’s important to take necessary precautions to ensure long-term structural stability and longevity against any external forces applied to it over time. Implementing these five preventative strategies ensures building a successful retainment wall system that stands strong for years yet to come.
