Retaining walls are essential structures that help prevent soil erosion,
and support slopes, creating a flat surface for building, gardening, or other activities. When choosing the right retaining wall for your project, you have several options, including segmental block and structural panel retaining walls.
This blog will discuss why a structural panel retaining wall is less expensive and more structurally sound than a segmental block retaining wall.
What is a Structural Panel Retaining Wall?
A structural panel retaining wall is a precast concrete wall, or raw galvanized wire, seated in a concrete or gravel footing. They consist of modular panels secured together to form a durable and stable retaining structure. These panels are made from high-strength concrete and reinforced with steel, making them capable of withstanding the immense pressure of soil and water.
A structural panel retaining wall can be used in various applications, including highway and bridge abutments, commercial and residential retaining walls, and waterfront protection.
Why is a Structural Panel Retaining Wall Less Expensive?
One of the primary reasons why a structural panel retaining wall is less expensive than a segmental block retaining wall is that it requires fewer materials and less labor to construct.
Structural Components
The structural components of a structural panel retaining wall are the gravel used as backfill, which would need to be utilized anyway, and the panels themselves. In contrast, a segmental block retaining wall requires a significant amount of blocks, gravel, and geogrids or geotextiles, all of which add up to a higher overall cost.
Human resources
A structural panel retaining wall requires less manpower than a segmental block retaining wall. Because the panels are precast and modular, they can be quickly and easily assembled on-site. On the other hand, a segmental block retaining wall requires a skilled workforce to place each block accurately, which is a time-consuming and costly process.
Wire Costs
Another reason a structural panel retaining wall is less expensive than a segmental block retaining wall is that wire costs less than concrete. Segmental block retaining walls require significant concrete to bond the blocks together, adding to the overall cost. In contrast, structural panel retaining walls use wire to bolt the panels together, a less expensive alternative.
Why is a Structural Panel Retaining Wall More Structural?
While a segmental block retaining wall is popular, it is more structurally sound than a structural panel retaining wall. Here are some reasons why:
Strength
A structural panel retaining wall is made from high-strength concrete, which can withstand higher loads than the blocks used in a segmental block retaining wall. The panels are also reinforced with steel, making them stronger and more durable.
Durability
Thanks to their durable and robust construction, structural panel retaining walls are designed to last for decades without any significant maintenance. In contrast, segmental block retaining walls can experience settlement, which can cause blocks to shift or topple over, leading to costly repairs and maintenance.
Design Flexibility
Because structural panel retaining walls are modular, they offer greater design flexibility than segmental block retaining walls. The panels can be arranged in various configurations to accommodate site conditions and project requirements, and this flexibility allows for a more tailored and cost-effective solution.
Ease of Installation
Structural panel retaining walls are easy to install, requiring less time and labor than segmental block retaining walls. This ease of installation translates into cost savings and a quicker project turnaround time.
Conclusion
In conclusion, while both structural panel and segmental block retaining walls have advantages, they are less expensive and more structurally sound than their segmental block counterparts. The structural components of a structural panel retaining wall are the gravel used as backfill and the panels themselves, while a segmental block retaining wall requires a significant amount of blocks.
For more information, give us a shout; we love this alternative to the block wall, as it has a better longevity value and is less expensive in the short- and long-term.
