The Essence of Terraced Retaining Walls
Transforming Slopes into Usable Spaces
Terraced retaining walls are designed to turn steep grades into a series of level sections or terraces. This approach is highly effective for creating more usable space in areas like Bayswater, where the terrain can vary. The spaces between the terraces can be utilized in several ways:
- For planting, enhancing the greenery and the environment.
- Filled with decorative rocks, adding a design element.
- Covered with sod to create uniform green spaces.
Structural Integrity and Safety
Building terraced retaining walls requires meticulous planning and execution, particularly in terms of soil compaction.
- Proper soil compaction ensures the stability of the terraces, especially important in areas like Onehunga, where soil conditions might vary.
- The lower terraced walls are typically built on solid ground, but the upper walls might be constructed on disturbed soils. These soils need to be removed and replaced with compacted wall rock or compacted in shorter lifts to prevent settling over time.
Design and Engineering Considerations
When constructing terraced retaining walls, certain engineering principles must be adhered to:
- The height of the upper retaining wall should generally be less than or equal to the height of the lower wall.
- The distance between the retaining walls must be at least twice the height of the lower wall.
- When an upper wall is placed closer to a lower one, it adds pressure to the lower wall. This requires additional reinforcement and careful engineering to ensure that the structure can withstand the added weight and pressure.
Health and Safety Considerations
Building retaining walls, especially terraced ones, involves significant earthmoving and construction activities. This process can pose risks such as wall collapse or injury from construction materials. Adhering to safety protocols and considering professional guidance, particularly for complex or taller walls, is essential.
